1.2.1106. Should Use Explode Args¶
explode() has a third argument, which limits the amount of exploded elements. With it, it is possible to collect only the first elements, or drop the last ones.
<?php
$exploded = explode(DELIMITER, $string);
// use explode(DELIMITER, $string, -1);
array_pop($exploded);
// use explode(DELIMITER, $string, -2);
$c = array_slice($exploded, 0, -2);
// with explode()'s third argument :
list($a, $b) = explode(DELIMITER, $string, 2);
// with list() omitted arguments
list($a, $b, ) = explode(DELIMITER, $string);
?>
