PHP编程：PHP清除数组中所有字符串两端空格的方法

function TrimArray($Input){
??? if (!is_array($Input))
??????? return trim($Input);
??? return array_map('TrimArray',$Input);
}
/*
Old version (v0.1):旧版本给大家作为对比参考：
function TrimArray($arr){
??? if (!is_array($arr)){ return $arr; }
??? while (list($key,$value) = each($arr)){
??????? if (is_array($value)){
??????????? $arr[$key] = TrimArray($value);
??????? }
??????? else {
??????????? $arr[$key] = trim($value);
??????? }
??? }
??? return $arr;
}
*/

//演示范例：
$DirtyArray = array(
??? 'Key1' => ' Value 1 ',
??? 'Key2' => '????? Value 2????? ',
??? 'Key3' => array(
??????? '?? Child Array Item 1 ',
??????? '?? Child Array Item 2'
??? )
);
$CleanArray = TrimArray($DirtyArray);
var_dump($CleanArray);
?
Result will be:
array(3) {
? ["Key1"]=>
? string(7) "Value 1"
? ["Key2"]=>
? string(7) "Value 2"
? ["Key3"]=>
? array(2) {
??? [0]=>
??? string(18) "Child Array Item 1"
??? [1]=>
??? string(18) "Child Array Item 2"
? }
}
