What potential issues can arise from using a variable in a loop without proper incrementation in PHP?

Using a variable in a loop without proper incrementation can lead to an infinite loop, where the loop never terminates because the variable does not change its value. To solve this issue, make sure to properly increment or decrement the variable within the loop to control the loop's execution.

// Incorrect loop without proper incrementation
$i = 0;
while ($i < 5) {
    echo $i;
    // Missing incrementation, causing an infinite loop
}

// Corrected loop with proper incrementation
$i = 0;
while ($i < 5) {
    echo $i;
    $i++; // Increment $i by 1 in each iteration
}
