How to Remove a Portion of a String After a Specific Substring in PHP

You can remove everything after a certain substring in PHP using the substr() function. The substr() function accepts three parameters:

  • The input string
  • The starting position
  • The length

To remove everything after a certain substring, you can use the strpos() function to find the position of the substring in the input string. Then you can use the substr() function to extract the portion of the string before the substring.

For example, the following code removes all the text including and after the substring "By" from the string "Posted On April 6th By Some Dude":

<code class="php">$string = "Posted On April 6th By Some Dude";
$substring = "By";

$position = strpos($string, $substring);

if ($position !== false) {
  $string = substr($string, 0, $position);
}</code>
Copy after login

After executing the above code, the value of the $string variable will be "Posted On April 6th".
