Also consider something like :
<?php
$var = 'a,b,c,';
$var[strrpos($var,',')] = ' ';
print $var; // 'a,b,c '
?>
The idea behind it is similar to this :
<?php
$s = 'abcabc'; // define our string
$s[1] = 'z'; // change second character in $s to 'z'
print $s; // azcabc
$key = strrpos($s,'c'); // 5 (pos of last 'c' in string $s)
print $s[$key]; // c
$s[$key] = 'z'; // change sixth character in $s to z
print $s; // azcabz
?>
Info to know :
strrpos() : Find position of last occurrence of a char in a string
strpos() : Find position of first occurrence of a char in a string
Looks like you found substr() , it helps out for these sorts of things
too :) If anyone has more information on this subject, please post.
