Get Data Between Two Elements
Ever had a bunch of text where you wanted some pieces of it? This snippet will get all between to elements. eg) [bob] where [ would be first element and ] would be second element.
Snippet:
-
<?
-
// returns an array from a string split by variable elements
-
// nongeek: gets something from between two other things
-
// http://thedevnet.com/php/snippets/get-data-between-two-elements/
-
-
function data_from_elements($needle_start, $needle_end, $haystack, $tags=false)
-
{
-
$pos_start = 0;
-
-
while(($pos_start = strpos($haystack,$needle_start,$pos_start)) !== false)
-
{
-
$pos_end = strpos($haystack,$needle_end,$pos_start);
-
-
if($tags)
-
$array[] = substr($haystack,$pos_start,$pos_end-$pos_start+strlen($needle_end));
-
else
-
$array[] = substr($haystack,$pos_start + strlen($needle_start),
-
$pos_end - $pos_start - strlen($needle_start));
-
-
$pos_start++;
-
}
-
-
return @$array;
-
}
-
?>
Example:
-
<?
-
$test = "[bob][jim][sue]";
-
-
print_r(data_from_elements("[","]",$test, true));
-
// Array ( [0] => [bob] [1] => [jim] [2] => [sue] )
-
-
print_r(data_from_elements("[","]",$test));
-
// Array ( [0] => bob [1] => jim [2] => sue )
-
?>
