How to Get Current Page URL using PHP

This php snippet prints current page url. It accepts a Boolean parameter as TRUE/FALSE which acts as a flag for displaying query string. It returns the current site URL.

/*
 * Fetches current URL via php
 * @$queryString = FALSE / TRUE
 * @returns the current page url
 */
 
function getCurrentUrl($queryString = TRUE) {
    $protocol = 'http';
    if ($_SERVER['SERVER_PORT'] == 443 || (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on')) {
        $protocol .= 's';
        $protocolPort = $_SERVER['SERVER_PORT'];
    } else {
        $protocolPort = 80;
    }
    $host = $_SERVER['HTTP_HOST'];
    $port = $_SERVER['SERVER_PORT'];
    $request = $_SERVER['PHP_SELF'];
    
    $query = ($queryString === TRUE) ? $_SERVER['QUERY_STRING'] : "";
    $url = $protocol . '://' . $host . ($port == $protocolPort ? '' : ':' . $port) . $request . (empty($query) ? '' : '?' . $query);
    return $url;
}

* Fetches current URL via php

* @$queryString = FALSE / TRUE

* @returns the current page url

function getCurrentUrl($queryString = TRUE) {

$protocol = 'http';

if ($_SERVER['SERVER_PORT'] == 443 || (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on')) {

$protocol .= 's';

$protocolPort = $_SERVER['SERVER_PORT'];

} else {

$protocolPort = 80;

}

$host = $_SERVER['HTTP_HOST'];

$port = $_SERVER['SERVER_PORT'];

$request = $_SERVER['PHP_SELF'];

$query = ($queryString === TRUE) ? $_SERVER['QUERY_STRING'] : "";

$url = $protocol . '://' . $host . ($port == $protocolPort ? '' : ':' . $port) . $request . (empty($query) ? '' : '?' . $query);

return $url;

}

Change Date Format mm/dd/yyyy to yyyy-mm-dd in PHP

One of the common situation I come across often, is to change the date format from mm/dd/yyyy to yyyy-dd-mm. It just take two lines of code to get the results.

<?php
$date = "10/24/2014";
$res = explode("/", $date);
$changedDate = $res[2]."-".$res[0]."-".$res[1];
echo $changedDate; // prints 2014-10-24
?>

<?php

$date = "10/24/2014";

$res = explode("/", $date);

$changedDate = $res[2]."-".$res[0]."-".$res[1];

echo $changedDate; // prints 2014-10-24

You can use an alternative approach also.

<?php
$date = "10/24/2014";
$date = DateTime::createFromFormat("m/d/Y" , $date);
echo $date->format('Y-m-d');
?>

<?php

$date = "10/24/2014";

$date = DateTime::createFromFormat("m/d/Y" , $date);

echo $date->format('Y-m-d');

Get IP Address Using PHP

There’s a lot of approach to get ip address in php. But here’s how I code when I need to get clients Ip address.

client IP AddressPHP

<?php
echo $_SERVER['REMOTE_ADDR'];
?>

client IP AddressPHP

<?php

echo $_SERVER['REMOTE_ADDR'];

Here’s an alternate approach as well, but I am not sure about this as HTTP_X_FORWARDED_FOR can be anything a client chooses to set, whereas REMOTE_ADDR is considerably harder to fake.

<?php
 $ipaddress = '';
    if ($_SERVER['HTTP_CLIENT_IP'])
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if($_SERVER['HTTP_X_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if($_SERVER['HTTP_X_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if($_SERVER['HTTP_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if($_SERVER['HTTP_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if($_SERVER['REMOTE_ADDR'])
        $ipaddress = $_SERVER['REMOTE_ADDR'];
    else
        $ipaddress = 'UNKNOWN';
    echo $ipaddress;
?>

<?php

$ipaddress = '';

if ($_SERVER['HTTP_CLIENT_IP'])

$ipaddress = $_SERVER['HTTP_CLIENT_IP'];

else if($_SERVER['HTTP_X_FORWARDED_FOR'])

$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];

else if($_SERVER['HTTP_X_FORWARDED'])

$ipaddress = $_SERVER['HTTP_X_FORWARDED'];

else if($_SERVER['HTTP_FORWARDED_FOR'])

$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];

else if($_SERVER['HTTP_FORWARDED'])

$ipaddress = $_SERVER['HTTP_FORWARDED'];

else if($_SERVER['REMOTE_ADDR'])

$ipaddress = $_SERVER['REMOTE_ADDR'];

else

$ipaddress = 'UNKNOWN';

echo $ipaddress;
