Question

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 'SOMEVALUE' 和 'string string string'

提前致谢

====== '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>'

Answer 1

你的正则表达式有点太复杂了，试试这样的：

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

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

而替换只是preg_replace().

这是我想出的答案：

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