What common mistakes should be avoided when using PHP loops?

One common mistake to avoid when using PHP loops is forgetting to increment the loop counter within the loop body. This can result in an infinite loop or incorrect results. To solve this issue, make sure to properly increment the loop counter within the loop body. 

// Incorrect way to use a for loop without incrementing the counter
for ($i = 0; $i < 5; ) {
    echo $i;
}

// Correct way to use a for loop with proper incrementation
for ($i = 0; $i < 5; $i++) {
    echo $i;
}
