The **`sleep`** method can be used to suspend the execution of a program  for a specific amount of time.

#     
## Syntax

---
    sleep(int $seconds): int
---

## Arguments

The `seconds` argument denotes the number of seconds the program execution needs to wait. 

The value should be positive; otherwise, the function will produce `E_WARNING`.  

## Return value

This method returns `0` upon success and `false` upon error. 

---
> If the waiting is interrupted by a `signal`, then the method returns a non-zero value. This value will always be `192` for Windows. For other operating systems, this value will be the number of seconds left to sleep.

## Code


<?php 

  echo "Time is : ".date('h:i:s').  "\n";
  $val = sleep(2);
  echo "Time is : ".date('h:i:s').  "\n";
  echo "Sleep method returned ". $val. "\n";
?>

#      
## Explanation

In the code above:

* We print the current time using `date('h:i:s')`. 

* We then call the `sleep(2)` method to make the program execution pause for two seconds.

* We print the time and value returned by the `sleep` method.
