在预浸比赛PHP

Question

我需要帮助创建一个正则表达式

blah blah blah blah <?= __l(array('key'=>'SOMEVALUE','default'=>'string string string')) ?>blah blah 

我希望能够剥离“someValue中”和“串串串”

感谢 在提前

======'这是我有'========

$subject = "Blah blah ja ja blah blah jank junk jonk <?= __l(array('key'=>'KEYKEYKEY','default'=>'I am a monkey sigh\'s')) ?> ldjlsakfdj as;dfj as;flkj a fsd ljaasfd <?= __l(array('key'=>'KEYKEYKEY','default'=>'I am a monkey sigh\'s')) ?> "; 
$pattern = '#\_\_l\(array\(\'key\'=>\'(.*)\',\'default\'=>\'(.*)\'\)\)#'; 



if (preg_match_all($pattern, $subject)) { 
print "A match was found."; 
} else { 
print "A match was not found."; 
} 

print '<br />'; 

preg_match_all($pattern, $subject, $matches); 

echo '<pre>'; 
print_r($matches); 
echo '</pre>' 

Answer 1

你的正则表达式有点太复杂，尝试这样的事情：

$regex = "/'key'=>'[^']+','default'=>'[^']+'/"; 
$string = preg_replace($regex, "'key'=>'','default'=>''", $string); 

的正则表达式是：

'key'=>'  - Match this literally 
[^']+   - Match anything that's not a single quote, one or more times 
','default'=>' - Match this literally 
[^']+   - Match anything that's not a single quote, one or more times 
'    - Match this literally 

和置换仅仅是第二个参数来preg_replace()。

这里是我想出了答案：

$pattern = '#\_\_l\(array\(\'key\'=>\'(.*?)\',\'default\'=>\'(.*?)\'\)\)#'; 

，但我喜欢你的答案更好nickb，所以我会投你了
