PHP: Remove all fcn not acting as expected, Code Inside
- by Josh K
I made this simple function (remove all $elem from $array):
function remall($array, $elem) {
for($i=0; $i < count($array); $i++)
if($array[$i] == $elem)
unset($array[$i]);
$newarray = array_values($array);
return $newarray;
}
But it isn't working perfectly, here are some inputs and outputs
$u = array(1, 7, 2, 7, 3, 7, 4, 7, 5, 7, 6, 7);
$r = remall($u, 7);
Output of $r: 12345767
$n = array(7, 7, 1, 7, 3, 4, 6, 7, 2, 3, 1, -3, 10, 11, 7, 7, 7, 2, 7);
$r = remall($n, 7);
Output of $r: 1346231-30117727
Notice how there are still 7s in my outputs.
Also, My function will only be removing numbers from an array.
Let me know if you spot something, thanks.
