How to Remove Text Within Parentheses in PHP?

Remove Text Between Parentheses in PHP

To eliminate text enclosed within parentheses along with the parentheses themselves in PHP, employ the preg_replace() function. It leverages regular expressions to search and modify strings.

The following code snippet accomplishes this task:

<code class="php">$string = "ABC (Test1)";
echo preg_replace("/\([^)]+\)/", "", $string); // 'ABC '</code>

Breakdown of the Code:

• preg_replace():

  • It takes three parameters:

    • Regular expression (with delimiters)
    • Replacement string (empty in this case)
    • Subject string

• Regular Expression:

  • The regular expression used is: /([^)] )/

    • It matches and targets the text within parentheses.

    • Here's a breakdown of the regular expression:

      • / - Delimiter
      • (: Matches an opening parenthesis
      • [^)S : Matches one or more characters (excluding the closing parenthesis)
      • ): Matches a closing parenthesis
      • /: Delimiter

In summary, the function replaces all instances of parentheses and their enclosed text with an empty string, effectively removing them from the original string.
