Example 1. Basic substr() usage
<?php
$rest = substr("abcdef", 1); // returns "bcdef"
$rest = substr("abcdef", 1, 3); // returns "bcd"
$rest = substr("abcdef", 0, 4); // returns "abcd"
$rest = substr("abcdef", 0, 8); // returns "abcdef"// Accessing via curly braces is another option
$string = 'abcdef';
echo $string{0}; // returns a
echo $string{3}; // returns d
?>If start is negative, the returned string will start at the start'th character from the end of string.
Example 2. Using a negative start
<?php
$rest = substr("abcdef", -1); // returns "f"
$rest = substr("abcdef", -2); // returns "ef"
$rest = substr("abcdef", -3, 1); // returns "d"
?>have fun

Hi,
I need to manipulate a string to insert a space 3 characters from the right end.
eg: turn 'ng23fgh' into 'ng23 fgh', or 'hfdgskfjgh23kj' into 'hfdgskfjgh2 3kj'.
Any help gratefully received.
