How can one troubleshoot issues with foreach loops not behaving as expected in PHP?

If a foreach loop is not behaving as expected in PHP, one common issue could be modifying the array being iterated over within the loop, causing unexpected behavior. To solve this, consider creating a copy of the array to iterate over instead. Another issue could be the array not being properly initialized or empty, resulting in the loop not executing. Check the array contents and ensure it is correctly populated before the foreach loop. 

// Example code snippet to troubleshoot foreach loop issues
$array = [1, 2, 3, 4, 5];

// Create a copy of the array to iterate over
$copyArray = $array;

foreach ($copyArray as $value) {
    // Perform actions with $value
}
