PHP in a Nutshell

Name

chr()

Synopsis

    string chr ( int ascii_val )

To convert an ASCII number to its character equivalent, use the chr() function. This takes an ASCII value as its parameter and returns the character equivalent, if there is one.

    $letter = chr(109);
    print "ASCII number 109 is equivalent to $letter\n";

That would output "ASCII number 109 is equivalent to m". The ord() function does the opposite of chr(): it takes a string and returns the equivalent ASCII value.
