What are some common mistakes made when using while loops in PHP, as seen in the code snippet provided?

One common mistake when using while loops in PHP is forgetting to update the loop control variable inside the loop, causing an infinite loop. To solve this issue, make sure to update the loop control variable within the loop to eventually meet the exit condition. Example of fixing the issue: 

// Incorrect code snippet
$count = 0;
while ($count < 5) {
    echo $count;
    // Missing incrementing $count, causing an infinite loop
}

// Corrected code snippet
$count = 0;
while ($count < 5) {
    echo $count;
    $count++; // Increment $count to eventually meet the exit condition
}
