In this article, we are going to learn how to Convert Text in CRC32 using PHP/MySQL. This simple program will demonstrate how to convert text in crc32. CRC32 creates 32-bit hash value. Creating simple TextBox, buttons, and another TextBox for viewing the result of CRC32 to the form field as in the image below. Result

Here's the source code in the image above.

<center>
	<div style="border:2px solid blue; background:azure; width:500px; padding:20px;">
		<form method="post">
			<h2 style="color:blue; font-family:cursive;">Convert Text to Crc32</h2><br>
			<input type="text" name="convert" style="padding:5px; font-size:18px; width:245px; font-family:cursive;" placeholder="Type Anything . . . . ." autofocus="autofocus">
			<input type="submit" name="crc32_convertion" value="Convert" style="padding:5px; font-family:cursive; font-size:18px; color:blue; background:azure; border:1px solid blue; border-radius:4px; cursor:pointer;">
		</form>
		<br>
			<h2 style="color:blue; font-family:cursive;">Crc32 Result</h2><br>
			<input type="text" value="" style="padding:5px; text-align:center; border:1px solid blue; color:white; font-size:18px; background:#1982d1; cursor:not-allowed; width:480px; " readonly><br><br>
	</div>
</center>

For the conversion of text to CRC32, we are going to put this PHP query to the TextBox to view the result. This is the PHP query.

<?php
 
if(isset($_POST['crc32_convertion'])){ echo crc32($_POST['convert']); } 
 
 ?>

Now, let's put to the TextBox.

<h2 style="color:blue; font-family:cursive;">Crc32 Result</h2><br>
<input type="text" value="<?php if(isset($_POST['crc32_convertion'])){ echo crc32($_POST['convert']); } ?>" style="padding:5px; text-align:center; border:1px solid blue; color:white; font-size:18px; background:#1982d1; cursor:not-allowed; width:480px; " readonly>

The complete source code.

<!DOCTYPE html>
