1.2.1309. Use Array Functions

There are a lot of native PHP functions for arrays. It is often faster to take advantage of them than write a loop.

• array_push() : use array_merge()

• array_slice() : use array_chunk()

• index access : use array_column()

• append []: use array_merge()

• addition : use array_sum()

• multiplication : use array_product()

• concatenation : use implode()

• ifthen : use array_filter()

<?php

$all = implode('-', $s).'-';

// same as above
$all = '';
foreach($array as $s) {
    $all .= $s . '-';
}

?>

See also Array Functions and No array_merge() In Loops.

1.2.1309.1. Suggestions

• Remove the loop and use a native PHP function

• Add more expressions to the loop : batching multiple operations in one loop makes it more interesting than running separates loops.
