What potential issues can arise when using strcmp() in a while loop in PHP?

Using strcmp() in a while loop in PHP can potentially lead to an infinite loop if the condition is not properly set. To avoid this, make sure to update the comparison values within the loop to eventually break out of it. One way to solve this is by setting a condition to compare the result of strcmp() to 0 within the loop and updating the comparison values accordingly.

$str1 = "Hello";
$str2 = "World";
$result = strcmp($str1, $str2);

while ($result != 0) {
    // Perform actions here
    
    // Update comparison values
    $str1 = "New value";
    $result = strcmp($str1, $str2);
}
