Get page URL

[chrisjwray]

Hi, can anybody tell me a function to get the name of the current page in PHP.

For example to call a function in index.php which will return "

http://servername/index.php"

Thanks in advance

Chris

You are looking for $PHP_SELF

Yep, PHP_SELF will return the name of the current page, but give this a go:

<?php
	$addr = "[URL unfurl="true"]http://".$_SERVER[/URL]['HTTP_HOST'].$_SERVER['PHP_SELF'];
	echo($addr);
?>

HMarcBower, Why not simply:

CODE
<?php
    $addr = "[URL unfurl="true"]http://{$_SERVER[/URL]['HTTP_HOST']}{$_SERVER['PHP_SELF']}";
    echo($addr);
?>

ps. I did not test your code, so I dont know if it is "perfect", but I know that gluing together strings is slow.

I didn't know concatenation was slow. What's your source?

DaButcher:
On my test system, I've found explicit use of the "." concatenation operator to be faster.

Here is my test code:

<?php
$foo = array ('one' => 'three', 'two' => '/four');

$start = microtime (TRUE);

for ($counter = 0; $counter < 1000000; $counter++)
{
	$addr = "[URL unfurl="true"]http://".$foo[/URL]['one'].$foo['two'];
	//$addr = "[URL unfurl="true"]http://{$foo[/URL]['one']}{$foo['two']}";
}

$end = microtime(TRUE);

print $end - $start;
?>

When the script is run as posted, the average runtime seems to be about 4.8 seconds. If I comment out the line which uses explicit concatenation and uncomment the line which uses implied (?) concatenation, the average runtime seems to be about 5.8 seconds.

Thanks guys, that was perfect . I needed a piece of code to switch language on a page without hard coding the page name.
Using

echo $_SERVER['PHP_SELF']."?lang=".$language

for the link sorted it.

Glad it worked for you Chris.

As for the concatenation... there are about six ways to do anything in PHP, it seems, and we all have our favourites.

uhm..
why not:
<a href="?lang=<?=$lang?>" title="Change language to <?=$lang?>" /><?=$lang?></a>
