How to Remove Text After a Specific Substring in PHP?

Deleting Data from a String After a Specific Point

In PHP, eliminating specific sections of a string after a particular substring can be a common task. Let's dive into this scenario:

You have a string containing information separated by subtexts, such as "Posted On April 6th By Some Dude." Your goal is to selectively remove everything, including the substring "By," from this string.

To achieve this, utilize the following code:

$variable = substr($variable, 0, strpos($variable, "By"));

This code effectively slices the string into two parts:

1. substr($variable, 0, ...): This section begins the extraction from the string's starting index (0) and continues until the specified point.
2. strpos($variable, "By"): This section determines the position of the "By" substring within the string.

Combining these actions, the code isolates the part of the string before the "By" substring, effectively stripping the designated portion from the original string.
