What potential issues can arise when using explode in a loop in PHP?

When using explode in a loop in PHP, a potential issue that can arise is if the delimiter used in explode is not found in some of the loop iterations, it can result in errors or unexpected behavior. To solve this issue, you can check if the explode function returns an array before trying to access its elements. 

foreach ($items as $item) {
    $parts = explode(',', $item);
    
    if (is_array($parts)) {
        // Access elements of $parts array safely
        foreach ($parts as $part) {
            // Process $part
        }
    }
}
