What potential issues or misunderstandings can arise when using logical operators in PHP loops?

One potential issue that can arise when using logical operators in PHP loops is the incorrect evaluation of conditions due to operator precedence. To avoid this, it's important to use parentheses to explicitly define the order of operations in complex conditions. 

// Example of using parentheses to clarify logical operators in a PHP loop
$numbers = [1, 2, 3, 4, 5];

foreach ($numbers as $number) {
    if (($number % 2 == 0) && ($number < 4)) {
        echo $number . " is an even number less than 4.\n";
    }
}
