What potential issue arises when using "return" in a PHP function within a loop?

Using "return" within a loop in a PHP function can cause the loop to terminate prematurely and return a value before completing all iterations. To solve this issue, you can store the return values in an array within the loop and return the array after the loop has completed.

function processArray($arr) {
    $result = array();

    foreach($arr as $item) {
        // Perform some operations on $item
        $result[] = $item;
    }

    return $result;
}
