求助：请问如何用正则验证 or 1 = 1
目的为了防止mysql注入操作。
------解决方案--------------------
[\s\S]*?or[\s\S]*?\d+[\s\S]*?=[\s\S]*?\d+
------解决方案--------------------
$a = array(<br /> "or 1 = 1",<br /> "Or 1 = 1",<br /> "or 3 =3",<br /> "or now() = now()",<br /> "or 'a' = 'a'",<br />);<br /><br />foreach($a as $s)<br /> echo $s, " :\t\t", preg_match('/or\b.+(\b\w+\b)[^=]*=.*\1/i', $s), PHP_EOL;or 1 = 1 : 1<br />Or 1 = 1 : 1<br />or 3 =3 : 1<br />or now() = now() : 1<br />or 'a' = 'a' : 1<br /><br />
