<?php
// convert current local time (IST) to GMT
// result: "15:06:25 30-Oct-06 GMT" (example)
echo gmdate("H:i:s d-M-y T") . "\n";

$ts = mktime(4,30,0,2,2,2005);
echo gmdate("H:i:s d-M-y T", $ts);
?>
Converting Between Different Time Zones
<?php
// function to get time
// for another time zone
// given a specific timestamp and hour offset from GMT
function getLocalTime($ts, $offset) {
// performs conversion
// returns UNIX timestamp
return ($ts - date("Z", $ts)) + (3600 * $offset);
}
// get current local time in Singapore

echo date("H:i:s d-m-y", getLocalTime(mktime(4,30,0,2,2,2005), 0)) .?
" GMT \n";
?>
Converting Between PHP
and MySQL Date Formats
<?php
// run database query, retrieve MySQL timestamp
$connection = mysql_connect("localhost", "user", "pass") ?
or die ("Unable to connect!");
$query = "SELECT NOW() AS tsField";
$result = mysql_query($query) ?
or die ("Error in query: $query. " . mysql_error());
$row = mysql_fetch_object($result);
mysql_close($connection);
// convert MySQL TIMESTAMP/DATETIME field
// to UNIX timestamp with PHP strtotime() function
// format for display with date()
echo date("d M Y H:i:s", strtotime($row->tsField));
?>
<?php
// run database query, retrieve MySQL timestamp
// convert to UNIX timestamp using MySQL UNIX_TIMESTAMP() function
$connection = mysql_connect("localhost", "user", "pass") ?
or die ("Unable to connect!");
$query = "SELECT UNIX_TIMESTAMP(NOW()) as tsField";
$result = mysql_query($query) or die ("Error in query: $query. " .
mysql_error());
$row = mysql_fetch_object($result);
mysql_close($connection);
// timestamp is already in UNIX format
// so format for display with date()
echo date("d M Y H:i:s", $row->tsField);
?>
To convert a UNIX timestamp to MySQL�s TIMESTAMP/DATETIME format,
use the date() function with a custom format strong, or use MySQL�s FROM_
UNIXTIME() function:
<?php
// create UNIX timestamp with mktime()
$ts = mktime(22,4,32,7,2,2007);
// turn UNIX timestamp into MYSQL TIMESTAMP/DATETIME format (string)
// result: "2007-07-02 22:04:32"
echo date("Y-m-d H:i:s", $ts);
// turn UNIX timestamp into MYSQL TIMESTAMP/DATETIME format (numeric)
// result: 20070702220432
echo date("YmdHis", $ts);
?>
<?php
// create UNIX timestamp with PHP mktime() function
$ts = mktime(22,4,32,7,2,2007);
// turn UNIX timestamp into MYSQL TIMESTAMP/DATETIME format
// using MySQL's FROM_UNIXTIME() function
$connection = mysql_connect("localhost", "user", "pass") ?
or die ("Unable to connect!");
$query = "SELECT FROM_UNIXTIME('$ts') AS tsField";
$result = mysql_query($query) or die ("Error in query: $query. " . ?
mysql_error());
$row = mysql_fetch_object($result);
mysql_close($connection);
// result: "2007-07-02 22:04:32"
echo $row->tsField;
?>
Comparing Dates
<?php
// create timestamps for two dates
$date1 = mktime(0,0,0,2,1,2007);
$date2 = mktime(1,0,0,2,1,2007);
// compare timestamps
// to see which represents an earlier date
if ($date1 > $date2) {
$str = date ("d-M-Y H:i:s", $date2) . " comes before " .?
date ("d-M-Y H:i:s", $date1);
} else if ($date2 > $date1) {
$str = date ("d-M-Y H:i:s", $date1) . " comes before " .?
date ("d-M-Y H:i:s", $date2);
} else {
$str = "Dates are equal";
}
// result: "01-Feb-2007 00:00:00 comes before 01-Feb-2007 01:00:00"
echo $str;
?>
Performing Date Arithmetic
<?php
// set base date
$dateStr = "2008-09-01 00:00:00";
// convert base date to UNIX timestamp
// expressed in seconds
$timestamp = strtotime($dateStr);
// express "28 days, 5 hours, 25 minutes and 11 seconds"
// in seconds
$intSecs = 11 + (25*60) + (5*60*60) + (28*24*60*60);
// add interval (in seconds)
// to timestamp (in seconds)
// format result for display
// returns "2008-09-29 05:25:11"
$newDateStr = date("Y-m-d h:i:s", $timestamp + $intSecs);
echo $newDateStr;
?>
Displaying a Monthly Calendar
<?php
// include Calendar class
include "Calendar/Month/Weekdays.php";
include "Calendar/Day.php";
// initialize calendar object
$month = new Calendar_Month_Weekdays(2008, 1);
// build child objects (days of the month)
$month->build();
// format as table
echo "<pre>";
// print month and year on first line
echo " " . sprintf("%02d", $month->thisMonth()) . "/" .?
$month->thisYear() . "\n";
// print day names on second line
echo " M T W T F S S\n";
// iterate over day collection
while ($day = $month->fetch()) {
if ($day->isEmpty()) {
echo " ";
} else {
echo sprintf("%3d", $day->thisDay()) . " ";
}
if ($day->isLast()) {
echo "\n";
}
}
echo "</pre>";
?>
Working with Extreme Date Values
<?php
// include ADODB date library
include "adodb-time.inc.php";
// get date representation for 01-Mar-1890
// returns "01-Mar-1890"
echo adodb_date("d-M-Y", adodb_mktime(4,31,56,3,1,1890)) . " \n";
// get date representation for 11-Jul-3690 10:31 AM
// result: "11-Jul-3690 10:31:09 AM"
echo adodb_gmdate("d-M-Y h:i:s A", adodb_mktime(16,1,9,07,11,3690)) . "
\n";
// get date representation for 11-Jul-3690 04:01 PM
// result: "11-Jul-3690 04:01:09 PM"
echo adodb_gmdate("d-M-Y h:i:s A", adodb_gmmktime(16,1,9,07,11,3690));

"USD"), "IN" => array(
"longname" => "India", "currency" => "INR"));
// print array contents
print_r($data);
var_dump($data);

Processing Arrays
<?php
// define indexed array
$idxArr = array("John", "Joe", "Harry", "Sally", "Mona");
// process and print array elements one by one

Processing Nested Arrays
<?php
// function to recursively traverse nested arrays
function arrayTraverse($arr) {
// check if input is array
if (!is_array($arr)) { die ("Argument is not array!"); }
// iterate over array
foreach($arr as $value) {
// if a nested array
// recursively traverse
if (is_array($value)) {
arrayTraverse($value);

// using whitespace as the separator
// result: ("a","b","c","d","e","f","g","h","i","j","k")
print_r(explode(" ", $alphabetStr));
?>
Swapping Array Keys and Values

// add an element to the end of the array
// result: ("spiderman", "superman", "the incredible hulk")
array_push($superheroes, "the incredible hulk");

print_r($superheroes);
// take an element off the end of the array
// result: ("the human torch", "superman")
array_pop($superheroes);
print_r($superheroes);
?>
Use PHP�s array_splice() function to add or remove elements from the
middle of an array:

echo (!isset($str) || trim($str) == "") ? "Empty" : "Not empty";
?>
Removing Characters from the Ends of a String
<?php
// define string
$str = "serendipity";
// remove first 6 characters

album; however, the lack of diversity and range is troubling, and I'm ?
hoping we see some new influences in the next album. More
intelligent lyrics might also help.";

preg_match_all("/<b>(.*?)<\/b>/i", $html, &$matches);
echo sizeof($matches[0]) . " occurrence(s)";
