Octal Character Codes

In PHP, you can insert characters into strings using their octal values. This is done by using a backslash followed by a three-digit octal number (e.g., \101 outputs the uppercase letter A). Below is a comprehensive list of octal codes for common control and printable characters.

EXAMPLE

<?php
// Outputting the word PHP using octal codes
$phpWord = "\120\110\120";
echo "Outputting codes \120\110\120: " . $phpWord . "<br>";

// Example with an exclamation mark and a space
$output = "\107\162\145\145\164\151\156\147\163\040\166\151\163\151\164\157\162\041";
echo "Result: " . $output . "<br>";
?>
