$bric = array("Brazil", "Russia", "India", "China"); $ric = $bric; // array copy $br = array_shift($ric); // left shift at $ric. $br stores "Brazil" print_r($bric); // $bric remains the same print_r($ric); // $ric lost "Brazil"
Output:
Array ( [0] => Brazil [1] => Russia [2] => India [3] => China ) Array ( [0] => Russia [1] => India [2] => China )
