What potential issues or errors should be considered when inserting a string at a specific position in PHP?

One potential issue when inserting a string at a specific position in PHP is that the position provided may be out of bounds, causing an error or unexpected behavior. To solve this, you can check if the position is within the bounds of the original string before inserting the new string.

function insertStringAtPosition($originalString, $newString, $position) {
    if ($position < 0 || $position > strlen($originalString)) {
        // Handle out of bounds position
        return "Position is out of bounds";
    }
    
    return substr_replace($originalString, $newString, $position, 0);
}

$originalString = "Hello world";
$newString = "beautiful ";
$position = 6;

$result = insertStringAtPosition($originalString, $newString, $position);
echo $result; // Output: Hello beautiful world
