How to Get the Substring Before the Last Character Occurrence in PHP?

Getting Substring Before Last Character Occurrence in PHP

In PHP, the strrchr() function finds the last occurrence of a character in a string. However, suppose you need to retrieve the substring preceding the last occurrence of a specific character. In that case, you can follow these steps:

1. Identify the Position of the Last Character Occurrence:

First, use strrpos() to determine the position of the last occurrence of the target character in the string. In your case, you want to find the position of the last space ' '.

<code class="php">$string = "Hello World Again";
$pos = strrpos( $string, ' '); </code>

2. Extract the Substring:

Once you have the position, use substr() to extract the substring up to that position.

<code class="php">echo substr($string, 0, $pos );</code>

This will output "Hello World", as desired.

Note: If the character is not found in the string, nothing will be echoed.
