how does one remove everything after a + in a php string?

[jonaofarc]

so we have a string like 4+1 I just want the 4 isolated from the + and the 1 any ideas?

any ideas?

You're not very specific. Under what conditions would you get a string like that? There are many ways, some regex based, some not. At it's simplest I'd use

 

$text = '4+1';
$text = substr($text, 0, 1);

 

or

 

$text = '4+1';
$text = current(explode('+', $text));

This is the correct way ill do it anyway......

<?php

$txt="4+1";

$x=preg_replace("/([1]){1}||([4]){1}/",' ',$txt);

echo $x;

?>
