If you try to use a foreach loop on a non-array variable in PHP, it will execute without error.

If you try to use a foreach loop on a non-array variable in PHP, it will result in a "Warning" notice. PHP will attempt to iterate over the non-array variable, considering it as an array with a single element. However, since it is not a valid array, the loop will execute only once. It is recommended to avoid using a foreach loop on non-array variables to ensure accurate and intended functionality. Learn more: https://www.php.net/manual/en/control-structures.foreach.php
