What could be causing the "Fatal error: Cannot use string offset as an array" in the PHP function mentioned in the forum thread?

The error "Fatal error: Cannot use string offset as an array" occurs when trying to access a string as an array in PHP. This typically happens when treating a string as an array and trying to access its elements using square brackets, which is invalid. To solve this issue, you need to make sure that the variable being accessed is actually an array before trying to use it as such. 

// Check if the variable is an array before accessing its elements
if (is_array($variable) && isset($variable['key'])) {
    // Access the array element
    $value = $variable['key'];
} else {
    // Handle the case where the variable is not an array or the key does not exist
    $value = null;
}
