What is the significance of storing the current server time in a PHP script for calculating remaining lock duration?

Storing the current server time in a PHP script is significant for accurately calculating the remaining lock duration. By storing the server time when the lock is initiated, we can compare it to the current server time to determine how much time has elapsed since the lock was set. This allows us to calculate the remaining lock duration and enforce the lock expiration accordingly. 

<?php
// Store the current server time when setting the lock
$lockStartTime = time();

// Perform some operations under the lock

// Calculate the remaining lock duration
$lockDuration = 60; // Lock duration in seconds
$elapsedTime = time() - $lockStartTime;
$remainingTime = $lockDuration - $elapsedTime;

if($remainingTime > 0) {
    echo "Lock will expire in " . $remainingTime . " seconds.";
} else {
    echo "Lock has expired.";
}
?>
