Let’s create an MD5 generator, if you don’t know what MD5 you are can visit read this Wikipedia article over MD5.


PHP 5.

Web server (Apache, Nginx, Lighttpd).

Writable web root.

First create a new file, you can name it whatever you want but to keep it simple I am naming it index.php.

We now must write some HTML that would have an input and a submit button, let’s do that.

<meta charset="utf-8"></meta> <title> MD5 Generator </title> <div class="container"> <h1 class="title">MD5 Generator</h1> <form action="index.php" method="post"> <input name="content" placeholder="Enter some text" type="text"></input> <input name="submit" type="submit" value="Hash!"></input> </form> <div> <p class="output"></p> </div> </div>
Code language: HTML, XML (xml)

Once you have written the basic HTML we require, you can add the PHP below in the top of the page that we will be using to check if the input isset or empty and hash the text.

The code below check if the input isset and checks if the input is left blank before the text is submitted , if not then the md5 function will continue and process the text and convert it into md5 hash

<?php if (isset($_POST['content'])) { if (!empty($_POST['content'])) { $hash = md5($_POST['content']); } } ??>
Code language: PHP (php)

Now we need to echo the hash by adding these lines.

<?php echo $hash ??>
Code language: PHP (php)

We can add the line above to the

We can add the line above to the `

that we had left empty, it should look something like this.

Now that we have our page styled the code should look something like this.

<p class="output"> <?php echo $hash; ??> </p>`
Code language: PHP (php)
<br> <span class="cp"> <span class="cp"> <span class="cp"> <?php if (isset($_POST['content'])) { if (!empty($_POST['content'])) { $hash = md5($_POST['content']); } } ?> </span> </span> </span>
Code language: PHP (php)
<div class="container"> <h1 class="title">MD5 Generator</h1> <form action="index.php" method="post"><input name="content" type="text" placeholder="Enter some text"><input name="submit" type="submit" value="Hash!"></form> <div> <p class="output"><?php echo $hash; ??></p> </div> </div>
Code language: PHP (php)

Now we have successfully created an md5 generator. If you have any questions, feel free to leave a comment below
