echo "The time in " . date_default_timezone_get() . " is " . date("H:i:s");
?>
Getting Current Timestamp in PHP
using time()
<?php $active_new_time_stamp = time(); echo $active_new_time_stamp; ?>
using strtotime()
<?php
$active_new_time_stamp = strtotime("now");
echo $active_new_time_stamp;
?>
using mktime()
<?php
$active_new_time_stamp_by_mktime = mktime(date("H"),date("i"),date("s"),date("m"),date("d"),date("Y"));
echo $active_new_time_stamp_by_mktime;
?>
using microtime()
<?php $active_new_time_stamp_string = microtime(); echo $active_new_time_stamp_string; $active_new_time_stamp_float = microtime(TRUE); echo $active_new_time_stamp_float; ?>
using Date
<?php
$active_new_time_stamp_fndate = date("U");
echo $active_new_time_stamp_fndate;

$strJsonFormat_with_space = json_encode($players_name, JSON_PRETTY_PRINT);
print "<hr/><hr/>JSON Formatted String with white space:" . $strJsonFormat_with_space;
?>
Example: json_decode()
$str_json_array_decoded = json_decode($player_json_format); print "<hr/><hr/>Resultant decoded array from JSON array:<hr/>"; print "<pre>"; print_r($str_json_array_decoded); print "</pre>"; $str_objJson_decoded = json_decode($obj_json_format); print "<hr/><hr/>Resultant decoded object data from JSON object:<hr/>"; print "<pre>"; print_r($str_objJson_decoded); print "</pre>"; $str_jsonAry_decoded = json_decode($obj_json_format,true); print "<hr/><hr/>Resultant decoded array data from JSON object:<hr/>"; print "<pre>"; print_r($str_jsonAry_decoded); print "</pre>";
