如何在PHP中使用正则表达式从简单括号中删除文本？

Question

Problem: Text sample - "Wanted String (unwanted)" . There is only one string inside parentheses.

I need to remove the "(unwanted)" including parentheses using RegEx in PHP.

Answer 1

If you have only one pair of parentheses, you can use the following two regexes and then concatenate their result. For eg, if your string is Wanted String (unwanted) and something after it , then:

• [^\\(]* will return Wanted String . (Working example: https://regex101.com/r/vZ6eG4/1 )
• (?<=\\)).* will return and something after it . (Working example: https://regex101.com/r/wL3aO9/1 )

Answer 2

$result = preg_replace('/\(.*?\)/', '', $subject);
