digui函数程序功能为通过递归正则匹配数字
如果是数字就保存到新数组中保存，最后返回所有包含数字的元素的数组
$array=array(
"22",
"1234",
array("a",
array("aab","00000","aaa","222000","3333000"),
"aa","999","aaaa"),
"d",
"567",
"33",
"dsf");
$fl_array=array();
function digui($arr)
{
global $fl_array;
foreach($arr as $key=>$value)
{
if (is_array($value))
{
digui($value);
}
}
$fl_array = preg_grep("/\d+/", $arr);
return $fl_array;
}
print_r(digui($array));
?>
$array=array( "22", "1234", array( "a", array("aab","00000","aaa","222000","3333000"), "aa","999","aaaa"), "d", "567", "33", "dsf");function digui($arr) { $fl_array = array(); foreach($arr as $key=>$value) { if(is_array($value)) { $fl_array = array_merge($fl_array, digui($value)); } } $fl_array = array_merge($fl_array, @preg_grep("/\d+/", $arr)); return $fl_array;}print_r(digui($array));
$result=array();global $result;function getNum($arr){ global $result; foreach ($arr as $value) { if(is_array($value)){ getNum($value); } if(is_numeric($value)){ array_push($result, $value); } } return $result;}print_r(getNum($array));
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
