幾個常用的去空、分組、調試數組函數_PHP教程

dump() 把數組以數組格式數組，有益於調試

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()去除數組中為空白的元素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預設函數 作用是把函數平均分組
