I have this PHP snippet:
<?php $colors = array('red','green','blue'); foreach ($colors as &$item) { $item = 'color-'.$item; } print_r($colors); ?> Output:
Array ( [0] => color-red [1] => color-green [2] => color-blue ) Is it simpler solution ?
(some array php function like that array_insert_before_all_items($colors,"color-"))?
Thanks
The method array_walk will let you 'visit' each item in the array with a callback. With php 5.3 you can even use anonymous functions
Pre PHP 5.3 version:
function carPrefix(&$value,$key) { $value="car-$value"; } array_walk($colors,"carPrefix"); print_r($colors); Newer anonymous function version:
array_walk($colors, function (&$value, $key) { $value="car-$value"; }); print_r($colors); 
$key, don't declare it.Alternative example using array_map: http://php.net/manual/en/function.array-map.php
PHP:
$colors = array('red','green','blue'); $result = array_map(function($color) { return "color-$color"; }, $colors); Output ($result):
array( 'color-red', 'color-green', 'color-blue' ) For older versions of php this should work
foreach ($colors as $key => $value) { $colors[$key] = 'car-'.$value; //concatinate your existing array with new one } print_r($sbosId); Result :
Array ( [0] => car-red [1] => car-green [2] => car-blue ) Try this:
$colors = array('red','green','blue'); function prefix_car( &$item ) { $item = "car-{$item}"; } array_walk( $colors, 'prefix_car'); It should work the same way you're doing it, albeit somewhat more sternly; array_walk gives an inkling more flexibility than manually looping.
$colors = array('red','green','blue'); $prefix = "car-"; $color_flat = $prefix . implode("::" . $prefix,$colors); $colors = explode("::",$color_flat); print_r($colors); 
$colors = array('red','green','blue'); $colors = substr_replace($colors, 'color-', 0, 0); print_r($colors);
