$t='

chrome
test
';
$pre_reg = '/ .*? preg_match_all($pre_reg,$t,$matches);
print_r($matches);

$t我省略了其他的，只留下了主要信息，但即便如此还是无法输出，请问这是什么问题
(我的原意是匹配 chrome 中的D8%C1%D0%CB%B9和chrome)


回复讨论(解决方案)

$pre_reg = '/

.*? 

$t='<tr><td><a href="/f?kw=chrome" title="chrome">chrome</a></td><tr><td><a href="/f?kw=%CA%A5%B0%B2%B5%" title="test">test</a></td>';$find='/href="\/f\?kw=([^"]*?)"\stitle="([^"]*?)"/s';preg_match_all($find,$t,$res);echo "<pre class="brush:php;toolbar:false">";print_r($res);echo "
Copy after login
Copy after login
";/*Array( [0] => Array ( [0] => href="/f?kw=chrome" title="chrome" [1] => href="/f?kw=%CA%A5%B0%B2%B5%" title="test" ) [1] => Array ( [0] => chrome [1] => %CA%A5%B0%B2%B5% ) [2] => Array ( [0] => chrome [1] => test ))*/
