time in php code example

Example 1: php get current date and time

$today = date("F j, Y, g:i a");   // October 30, 2019, 10:42 pm
$today = date("D M j G:i:s T Y"); // Wed Oct 30 22:42:18 UTC 2019
$today = date("Y-m-d H:i:s");     // 2019-10-30 22:42:18(MySQL DATETIME format)

Example 2: php time a script

//place this before any script you want to calculate time
$time_start = microtime(true); 

//sample script
for($i=0; $i<1000; $i++){
 //do anything
}

$time_end = microtime(true);
$execution_time = ($time_end - $time_start);
echo '<b>Total Execution Time:</b> '.($execution_time*1000).'Milliseconds';

Example 3: php date timestamp now

//Get current date time in PHP

// Simply:
$date = date('Y-m-d H:i:s');

// Or:
$date = date('Y/m/d H:i:s');

// This would return the date in the following formats respectively:
$date = '2012-03-06 17:33:07';
// Or
$date = '2012/03/06 17:33:07';

/** 
 * This time is based on the default server time zone.
 * If you want the date in a different time zone,
 * say if you come from Nairobi, Kenya like I do, you can set
 * the time zone to Nairobi as shown below.
 */

date_default_timezone_set('Africa/Nairobi');

// Then call the date functions
$date = date('Y-m-d H:i:s');
// Or
$date = date('Y/m/d H:i:s');

// date_default_timezone_set() function is however
// supported by PHP version 5.1.0 or above.

Example 4: human time php

// for a human time string like: "It's around ten past twelve" 
// usage: echo 'It\'s ' . humanTime(date('h'), date('i'));

function humanTime($hour, $min) {
    $times = [
        0 => '%s o\'clock',
        2 => 'a couple of mins past %s',
        5 => 'five past %s',
        8 => 'around ten past %s',
        10 => 'ten past %s',
        15 => 'quarter past %s',
        20 => 'twenty past %s',
        25 => 'twenty five past %s',
        27 => 'around half past %s',
        30 => 'half past %s',
        33 => 'around thirty five past %s',
        35 => 'thirty five past %s',
        40 => 'twenty to %s',
        43 => 'around quarter to %s',
        45 => 'quarter to %s',
        47 => 'about ten to %s',
        50 => 'ten to %s',
        53 => 'about five to %s',
        55 => 'five to %s'
    ];
    
    $hourWord = [
        'one',
        'two',
        'three',
        'four',
        'five',
        'six',
        'seven',
        'eight',
        'nine',
        'ten',
        'eleven',
        'twelve'
    ];

    $hour = (int) $hour;
    $min = (int) $min;
    
    $closest = null;
    foreach ($times as $key => $item) 
        if ($closest === null || abs($min - $closest) > abs($key - $min)) $closest = $key;
    
    if ($hour === 0) $hour = 12;
    
    if ($min > 40) $hour = $hour === 12 ? 1 : $hour + 1;

    return sprintf($times[$closest], $hourWord[(int) $hour - 1]);
}

Example 5: time php

/* Unix Timestamp */
$timestamp = time();
echo $timestamp . "<br>";
echo date("d/m/Y", $timestamp);
?>

Example 6: php time
