Integrating Photos in PHP

“The digital revolution is far more significant than the invention of writing or even of printing.” – Douglas Engelbart

According to recent studies, we’re spending more and more time in front of screens. We now spend an entire day of every week on our smartphones.

Computers, TVs, and smartphones have revolutionised the way we live.

So how can we get the most out of them?

PHP is an easy-to-use programming language. It’s used in web development to programme web apps and code websites and has a number of useful features. Tags, hosting, resizing an image, etc., there are plenty of things you can learn to do with PHP programming.

In this article, we’re going to look at what PHP is, why you should use it to display images, the code you’ll need to display images, and how to create and display PHP images.

What is PHP?

Before we start explaining anything, we need to understand what PHP is. PHP is a programming language that was created in 1994 by Rasmus Lerdorf and can be used to create dynamic websites. There’s no need to be a web designer, programmer, or developer to start using it. PHP is famous for just how accessible it can be after just a few hours of training.

PHP is an open-source scripting language. This means that it can be freely used and modified by anyone. This is why a whole community grew around the language. Enthusiastic coders took joy in adding functionality right from the start. That’s how we ended up with seven versions of PHP. Special characters, algorithmic image sources, jpeg formats, regular expressions, etc. PHP is a rich language.

But what makes scripting with PHP different?

There are plenty of programming and scripting languages that can be used in web development, web applications, and web programming. Java, C++, JavaScript, Python, HTML, etc. There are plenty of ways to get a computer to understand what you want to do.

PHP allows you to create dynamic websites. In other words, the pages created with this programming language will display differently depending on who opens it. This functionality is very useful for creating things such as member areas.

Whether it’s learning about managing databases, development environments, HTML, syntax, script, command lines, server side, or HTML pages, learning to code with PHP requires work. However, you can get the basics down quite quickly.

Why Display or Create a PHP Image?

PHP was just a way for its creator to see how many people were looking at his CV on his website. Bit by bit, users developed functions for this programming language. Since it was free to use, programmers had a field day!

Today, PHP is known for creating websites but it can also be used to create images and text.

The images are written into the PHP code and interpreted by web servers. This is how the language works. That said, the images do need to be stored in a PHP file.

Creating or displaying an image can make a website look better. Many PHP developers use it to simplify lines of code and save time.

The Code for Adding a PHP Image

To add images to your website or project, the PHP language could be useful. This programming language isn’t just for creating web pages. You can also use it to add images to your site.

There are two different ways to do this. The first involves using the web page itself. Instead of a web page, you just need to include the image’s code. Then to see the image, you just need to add “.php” to make it appear on the page.

The second method involves storing the photo in a file.

In both cases, you need to know which code to make the site display the image. To do this, you need to start with the header.

The header is a code that allows the server to know that you want to display an image on the page. This means the image will display correctly.

The code for the header is as follows:

<?php

header (“Content-type: image/jpeg”);

?>

This line of code will return a .jpg image and not an HTML page. Of course, in IT, there are many different image formats. You can also use .png, for example. These are of a higher quality and better for photos. To insert a .png image, you just need to replace “jpg” with “png”.

How to Create a PHP Image

Now that you know how to insert images, you should know how to use an image and put it into PHP code.

Once you’ve saved and named your image, what can you do with it?

The previous code is just the beginning. It’s not the whole thing. You’ve just told the server that you’re going to display an image and not an HTML page. You’ve not told them which image you want to display. To insert an image, you can create one or use an existing image.

If you want to create an image, you’ll need to use the “imagecreate” function. This allows you to decide the size of your image. Thus, you’ll write the height and width as follows:

<?php

header (“Content-type: image/png”);

$image = imagecreate(300,100);

?>

The term “$image” indicates that the data is variable. This means it can be changed. In this case, the image is 300 pixels wide and 100 pixels high. You can add information about the image.

If you want to use an image that’s already been saved, you just need to use the “imagecreatefromjpeg” or “imagecreatefrompng” functions. Let’s image we have a file named “myphoto.jpg”. You’ll need to use the code as follows:

<?php

header (“Content-type: image/jpeg”);

$image = imagecreatefromjpeg(“myphoto.jpg”);

?>

Don’t forget to close the PHP code with “?>”.

How to Display a PHP Image

You haven’t finished coding yet. The server has all the information about the image but it doesn’t know what it needs to display. The image is contained in the code but you can’t see it on the site. In this case, you need to add the last line using the “imagejpeg” or “imagepng” functions.

The code will be as follows:

<?php

header (“Content-type: image/jpeg”);

$image = imagecreatefromjpeg(“myphoto.jpg”);

imagejpg($image);

?>

In this case, the image will be directly displayed on the site. To display it on another page, you’ll need to use the HTML code <img src= “myphoto.php” />.

You can also save a photo or image without displaying on the site. In this case, you can use the “imagejpg” or “imagepng” function followed by the image name and folder name. This script will indicate to the server to save the file and not display it:

<?php

header (“Content-type: image/jpeg”);

$image = imagecreatefromjpeg(”);

imagejpg($image); (“myphotos/myphoto.jpg”);

?>

The image will be saved in the “my photos” folder.

In this case, you don’t need the header function because you’re dealing with just an image and not a website. You’re just saving the image. You can display it using the following code:

<img src= “myphotos/myphoto.jpg”/>

You now know the PHP functions needed to display an image. There are other functions for adding text to the images you add, but we’ll save that for another day.

You can always practise by creating your own website. You learn from making mistakes.

If you need more help, you can always get tutorials and learn PHP from a tutor on Superprof. In fact, you can get tutorials on all types of object-oriented programming, PHP scripts, MySQL, Perl, Apache, Zend, or server-side scripting.

How To Learn PHP

If you are new to PHP, then there are various ways you can learn about using the language.

Learning PHP With Superprof

Superprof lets you search through a wide database of tutors. All you need to do is enter your postcode and the subject you’re looking for a tutor for, and you’ll be shown all the available tutors in your area, as well as those offering remote tuition.

There are three types of tutorials available on the platform: face-to-face tutorials, online tutorials, and group tutorials and each type has its pros and cons.

Face-to-face tutorials are usually the most expensive but they’re also the most cost-effective since you’ll be the only student in the class and the tutor can focus entirely on you.

Online tutorials tend to cost less since the tutor doesn’t have to worry about their travel costs to and from the student. While these aren’t ideal for subjects that require a hands-on approach, they can be really effective for technical subjects like IT.

Group tutorials are usually the cheapest per hour since the cost of the lesson is shared amongst all of the students in attendance. Of course, this does mean that you’ll get less personal attention from your tutor.

Don’t forget that a lot of the tutors also offer the first hour of tutoring for free. You can use this time to see if you get along with them if their teaching approaches are right for you, and discuss what you want and expect from your private tutorials.

Alternatively, you can opt for classes at an institution near you.

PHP And Web Development Courses

Cardiff University – PHP3 – PHP Web Application Development

“Thursdays from 18:00 to 21:00 plus 1 Saturday Day School

Duration 12 weekly meetings plus 1 Saturday Day Schools
Tutor Christopher Maggs
Course code COM19A5213A
Fee £450
Concessionary fee

This course introduces object oriented PHP and the use of software design patterns for practical web application development.

The course covers development of PHP classes and methods in order to create and maintain web applications. It covers the separation of the different parts of a web application and their relationships through object oriented programming and demonstrates their use in practical web development.

This course is ideal for the student who already has some knowledge of the PHP programming language.

Learning and teaching

This module includes a mix of traditional lectures and laboratory sessions.

The course will teach the fundamentals of Object Oriented programming applicable to PHP and will cover the use of Classes, Methods, and their relationships.

It will cover the generation of Objects through class instantiation, inheritance and extending classes. This will be achieved through a number of individual projects requiring some level of PHP development that will be covered during the lessons.

The course will continue with examples of typical software design patters that use OO style programming to achieve a maintainable web application, and will discuss the advantages / disadvantages of different methods.

The secondary purpose of this section will be for the student to decide which style they will use for the final part of the course.

The course will then provide the opportunity for each student to select a suitable web application and follow their chosen design method to generate their own functional web application. Students will be given the opportunity to either use a pre-existing template or to use their own time to create a more personal bespoke application.

Coursework and assessment

To award credits we need to have evidence of the knowledge and skills you have gained or improved. Some of this has to be in a form that can be shown to external examiners so that we can be absolutely sure that standards are met across all courses and subjects.

During the course, you will be given assignments to be submitted to the course tutor. At the end of the course, there will be a class test.

The most important element of assessment is that it should enhance your learning. Our methods are designed to increase your confidence and we try very hard to devise ways of assessing you that are enjoyable and suitable for adults with busy lives.
