回复讨论(解决方案)

学到这里卡住了

有没有大神能帮帮忙

贴出你的代码

应该是你的正则表达式不正确(为空)

。。。。。。

$perg='/\d{3,4}-?\d{7,8}/';
$arr=array('043212345678','0431-7654321','12345678');
$preg_arr=preg_grep($prdg,$arr);
var_dump($preg_arr);

?>

$preg_arr=preg_grep( $perg,$arr);

求帮忙看看。。

$perg='/\d{3,4}-?\d{7,8}/';
$arr=array('043212345678','0431-7654321','12345678');
$preg_arr=preg_grep( $prdg,$arr);
var_dump($preg_arr);

一样吗?初学,首先就要学会细心

万分感谢啊,打错了,唉,新手学习中,谢谢了
