1.2.304. Could Use array_unique¶
Use array_unique() to collect unique elements from an array.
Always try to use native PHP functions, instead of rebuilding them with custom PHP code.
<?php
$unique = array();
foreach ($array as $b) {
if (!in_array($b, $unique)) {
/* May be more code */
$unique[] = $b;
}
}
?>
See also array_unique.
1.2.304.1. Suggestions¶
Turn the foreach() and its condition into a call to array_unique()
Extract the condition from the foreach() and add a separate call to array_unique()
