几个常用的去空、分组、调试数组函数_PHP教程

dump() 把数组以数组格式数组，有益于调试

function dump($vars, $label = , $return = false){
if (ini_get(html_errors)) {
$content = "

";

        if ($label != ) {

            $content .= "{$label} :
";

        }

        $content .= htmlspecialchars(print_r($vars, true));

        $content .= "

";
} else {
$content = $label . " : " . print_r($vars, true);
}
if ($return) { return $content; }
echo $content;
return null;
} array_remove_empty()去除数组中为空的元素 function array_remove_empty(& $arr, $trim = true){
foreach ($arr as $key => $value) {
if (is_array($value)) {
array_remove_empty($arr[$key]);
} else {
$value = trim($value);
if ($value == ) {
unset($arr[$key]);
} elseif ($trim) {
$arr[$key] = $value;
}
}
}
} array_chunk() php默认函数 作用是把函数平均分组
