我需要帮助创建正则表达式
blah blah blah blah <?= __l(array('key'=>'SOMEVALUE','default'=>'string string string')) ?>blah blah
我希望能够剥离"SOEVALUE"answers"字符串字符串"
谢谢提前
======"这就是我所拥有的"===
$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>'
您的正则表达式有点太复杂了，请尝试以下操作：
$regex = "/'key'=>'[^']+','default'=>'[^']+'/";
$string = preg_replace( $regex, "'key'=>'','default'=>''", $string);
正则表达式为：
'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
而替换只是CCD_ 1的第二个参数。
这是我得出的答案：
$pattern = '#'_'_l'(array'(''key''=>''(.*?)'',''default''=>''(.*?)''')')#';
但我喜欢你更好地回答nickb，所以我会投票支持你的
