Examples

Example #1 time_nanosleep() example

<?php
// Careful! This won't work as expected if an array is returned
if (time_nanosleep(0500000000)) {
    echo 
"Slept for half a second.\n";
}

// This is better:
if (time_nanosleep(0500000000) === true) {
    echo 
"Slept for half a second.\n";
}

// And this is the best:
$nano time_nanosleep(2100000);

if (
$nano === true) {
    echo 
"Slept for 2 seconds, 100 microseconds.\n";
} elseif (
$nano === false) {
    echo 
"Sleeping failed.\n";
} elseif (
is_array($nano)) {
    
$seconds $nano['seconds'];
    
$nanoseconds $nano['nanoseconds'];
    echo 
"Interrupted by a signal.\n";
    echo 
"Time remaining: $seconds seconds, $nanoseconds nanoseconds.";
}
?>
