Hexadecimal Character Codes

In PHP, you can insert characters into strings using their hexadecimal values. This is done by using the \x escape sequence, followed by a two-digit hexadecimal code (e.g., \x41 outputs the letter A). Below is a list of the most common printable characters and their corresponding codes.

EXAMPLE

<?php
// Outputting the word PHP using hexadecimal codes
$phpWord = "\x50\x48\x50";
echo "Outputting codes \x50\x48\x50: " . $phpWord . "<br>";

// Example with an exclamation mark and a space
$output = "\x47\x72\x65\x65\x74\x69\x6E\x67\x73\x20\x76\x69\x73\x69\x74\x6F\x72\x21";
echo "Result: " . $output . "<br>";
?>
