Yeah, me too -- here are three routines I use for cutting the right,
left and middle portions of strings. These were keyword routines I
used in FutureBasic -- they seemed to make sense to me so I carried
them into php.
<?php
// ====== returns the right-most number of characters from a string
// $string = "123456789"
// right($string, 3) returns "123"
function right($string, $length)
{
$str = substr($string, -$length, $length);
return $str;
}
// ====== returns the left-most number of characters from a string
// $string = "123456789"
// left($string, 3) returns "789"
function left($string, $length)
{
$str = substr($string, 0, $length);
return $str;
}
// ====== returns the middle number of characters from a string
starting from the left
// $string = "123456789"
// mid($string, 3, 4) returns "4567"
function mid($string, $left_start, $length)
{
$str = substr($string, $left_start, $length);
return $str;
}
?>
