使用正则表达式替换带有相同字符串的字符串，并使用php删除引号（“）

Question

I have a multi-line string shown below -

   ?a="text1
    ?bc="text23

I need to identify a pattern like using below regex

  '/[?][a-z^A-Z]+[=]["]/'

and replace my string by just remove the double quote (") in it, expected output is shown below

?a=text1
?b=text23

Please help in solving the above issue using php.

Capture everything except the quote in a capture group () and replace:

$string = preg_replace('/([?][a-z^A-Z]+[=])["]/', '$1', $string);

But you really don't need all those character classes []:

/(\?[a-z^A-Z]+=)"/
