Made this function to delete elements in an array;
<?php
function array_del_elm($input_array, $del_indexes) {
if (is_array($del_indexes)) {
$indexes = $del_indexes;
} elseif(is_string($del_indexes)) {
$indexes = explode($del_indexes, " ");
} elseif(is_numeric($del_indexes)) {
$indexes[0] = (integer)$del_indexes;
} else return;
$del_indexes = null;
$cur_index = 0;
if (sort($indexes)) for($i=0; $i<count($input_array); $i++) {
if ($i == $indexes[$cur_index]) {
$cur_index++;
if ($cur_index == count($indexes)) return $output_array;
continue;
}
$output_array[] = $input_array[$i];
}
return $output_array;
}
?>
but then i saw the methods of doing the same by Tyler Bannister & Paul, could see that theirs
were faster, but had floors regarding deleting multiple elements thus support of several ways of
giving parameters. I combined the two methods to this to this:
<?php
function array_del_elm($target_array, $del_indexes) {
if (is_array($del_indexes)) {
$indexes = $del_indexes;
} elseif(is_string($del_indexes)) {
$indexes = explode($del_indexes, " ");
} elseif(is_numeric($del_indexes)) {
$indexes[0] = (integer)$del_indexes;
} else return;
unset($del_indexes);
for($i=0; $i<count($indexes); $i++) {
unset($target_array[$indexes[$i]]);
}
return $target_array;
}
Fast, compliant and functional ;)
