Character encoding is useful in web development for generating character strings from random numbers (CAPTCHA images for instance), displaying non-standard characters and many other purposes.
To use charachter encoding with PHP or To use ASCII value with PHP, we have a function to print ASCII value.
string chr ( int $ascii )
ascii
The ASCII code
Output:
Returns the specified character.
For Example:
/* Often this is more useful */
<?php
$str = "The string ends in escape: ";
$str .= chr(27); /* add an escape character at the end of $str */$str = sprintf(“The string ends in escape: %c”, 27);
?>
