我有这样一个阵列:
$a = array( aa , bb , cc , dd );
我要补充一下阵列所有要素一开始的 r。 是否有可能通过在这种阵列上阵列——地图?

$a = array_map(function ($str) { return "rq$str"; }, $a);
function addRq($sValue) {
return rq .$sValue;
}
$newA = array_map("addRq", $a);
另见example 。
You can have it like this:
<?php
$a = array( aa , bb , cc , dd );
$i=0;
foreach($a as $d) {
$a[$i] = rq .$d;
$i++;
}
var_dump($a);
?>
