How to Delete Text After a Specific Substring in PHP?

Deleting Text After a Specific Substring

Removing text from a string after a particular substring is straightforward in PHP. Consider the example string:

Posted On April 6th By Some Dude

If you wish to delete all characters, including and following the substring "By", follow these steps:

<code class="php">$variable = substr($variable, 0, strpos($variable, "By"));</code>

This code employs the substr(), and strpos() functions:

• substr(): Accepts three parameters: the string, the starting position, and the ending position. In this case, we start from the beginning (0) and end at the position of the substring "By".
• strpos(): Determines the position of the first occurrence of the substring "By" within the string.

Breaking this down in plain English:

Give me the portion of the string that starts from the beginning and ends at the point where you first encounter the substring "By".

Executing this code would result in:

Posted On April 6th

This method effectively removes everything after the specified substring.
