What are common debugging techniques for identifying issues in PHP loops?

One common debugging technique for identifying issues in PHP loops is to use print statements to output the values of variables at different points within the loop. This can help identify where the issue is occurring and what values the variables are taking on. Another technique is to step through the loop using a debugger to see how the variables are changing at each iteration. Additionally, checking for common mistakes such as off-by-one errors or incorrect loop conditions can help pinpoint the issue.

// Example of using print statements to debug a loop
$numbers = [1, 2, 3, 4, 5];
$total = 0;

foreach ($numbers as $number) {
    $total += $number;
    echo "Current number: $number, Total: $total\n";
}
