How to Remove Text Enclosed in Parentheses Using PHP?

Stripping Text from Parentheses in PHP

Question:

How can I eliminate text enclosed in parentheses and the enclosing parentheses itself using PHP?

Example:

Given the input "ABC (Test1)", the desired output is "ABC".

Answer:

preg_replace is a built-in PHP function that allows for powerful string manipulation using regular expressions. Here's how you can achieve the desired result:

<?php
$string = "ABC (Test1)";
echo preg_replace("/\([^)]+\)/","",$string); // Output: ABC
?>

Explanation:

• preg_replace takes three arguments:

  • The regular expression pattern
  • The replacement string (empty in this case as we're not replacing with anything)
  • The target string to be processed

The regular expression pattern in our case is:

/  - Opening delimiter (necessary for regular expressions, can be any character that doesn't appear in the regular expression
\( - Match an opening parenthesis
[^)]+ - Match 1 or more characters that are not closing parentheses
\) - Match a closing parenthesis
/  - Closing delimiter

This expression matches all instances of an opening parenthesis followed by one or more non-parentheses characters followed by a closing parenthesis. The matched pattern is then deleted, resulting in the desired output.
