1.2.1126. Simplify Foreach¶
Remove all unused keys or values from a foreach() call. This prevents PHP from assigning them for nothing, and save some processing time.
This is a micro-optimisation.
<?php
// No key usage
foreach($array as $key => $value) {
echo $value;
}
// No value usage
foreach($array as $key => $value) {
echo $key;
}
?>
1.2.1126.1. Suggestions¶
Use array_keys() or array_values() to simplify the source array
Remove the call to $key => when the key is not used in the loop
