How could I cut off text after a keyword?

Question

So say I would write something like <break> and it would show everything before <break> out of

$text = "I like apple pies<break>Do you like Apple pies?";

So it should only output

I like apple pies

$text = "I like apple pies<break>Do you like Apple pies?";

list($result) = explode('<break>',$text,2);

<3, big duh on my part. Especially like the elegance of using `list()` – Kevin Peno Mar 18 '11 at 15:28

`list($result) = explode('',$text,2);` is more efficient, especially if the string is long after the `` mark (php doesn't have to search the whole string). – Czechnology Mar 18 '11 at 15:43

As a function:

function BeforeBreak($input)
{
    return stristr($input, '<break>', true);
}

Note this functionality requires PHP 5.3.0.

Please note that this will perform a case-insensative search for ``. The function would be a great idea, +1. – Michiel Pater Mar 18 '11 at 15:49
This is done to accept `` as well, but use `strstr` instead if the case sensitivity is important. – JYelton Mar 18 '11 at 15:53

Try this:

$text = "I like apple pies<break>Do you like Apple pies?";
$texplode = explode('<break>',$text);
echo $texplode[0];

$good = substr( $bad, 0, strpos( $bad, "<break>" ) );

this will give you what you want:

<?
   $output = strstr($text, '<break>', true);
?>

if you have multiple occurrences it's a good idea to use

<?
   $text = 'a<break>b<break>c<break>d';
   $output = explode('<break>', $text);

   // the output will be
   // array('a', 'b', 'c', 'd');
?>

Please note that you will need to have PHP 5.3.0 installed to be able to use the `before_needle` parameter. Nice answer though, +1. – Michiel Pater Mar 18 '11 at 15:44
