How can I remove a specific number of characters from a string in PHP?

Solution:

You can use PHP’s substr() function for different substring operations:

1. First $n characters

substr($text, 0, $n);

2. Substring between two positions
Example: from position $a = 5 to $z = 12 → “quick br”

substr($text, $a, ($z - $a));

3. Last $n characters

substr($text, -$n);
