My input is as below:
*test*
The output I want is content inside two asterisks (test).
My code is as below:
preg_match('/^(\*(.*)\*)$/','*test*',$matches);
Its output is:
Array ( [0] => *test* [1] => *test* [2] => test )
The third one is the one I want. I know why it does this, but I don't know how to solve it. How to write an RE that returns just test nothing else.
您可以使用前瞻和后瞻断言 :
/(?<=^\*).*(?=\*$)/
you can try this by using explode function :
<?php $str = '*test*';
$str1 = explode('*', $str);
echo $str1[1];
?>
