pull string from URL

[Imaulle]

Hello!

 

I'm trying to make a php script to help streamline a ton of website setups that I need to do. What I want for this function is to pull the 'username' from the url. The url will always look something like this:

 

http://75.0.0.0/~username/folder/setup.php

 

what is the easiest way to get just 'username' so that I can put it into a variable ?

 

thanks!

One way is to use $_SERVER['PHP_SELF'] which will return you "/~username/folder/setup.php", then explode it by "/", will get the result.

hmmm

 

would this work?

 

$username = explode('/',$_SERVER['PHP_SELF']);

[PravinS]

It will return array.

 

$username[1] will return you actual username.

[Imaulle]

almost got it! lol

 

with this code

 

$geturl = explode("/",$_SERVER['PHP_SELF']);
$username = $geturl[1];

 

it returns '~user'

 

how do I get rid of the ~

 

p.s. thanks so much for helping me

[PravinS]

Use

 

$username = substr($geturl[1], 1);

awesome! thank you dude

crap, okay new problem! lol this should be really easy but I'm only really good at c++

 

line 9, the $DB_NAME isn't getting printed to the file. How do I get it to print the variable name and not try to print the contents? putting it in single and double quotes didn't work 

 

$getURL = explode("/",$_SERVER['PHP_SELF']);
$username = substr($getURL[1], 1);

$addInfo="<?php
define ('DB_USER', '".$username."_stuff');
define ('DB_PASSWORD', 'pass');
define ('DB_HOST', 'localhost');
define ('DB_NAME', '".$username."_stuff');
'$DB_NAME' = '".$username."_stuff';";

$dbinfoFile = "dbinfo.php";
$contents = file_get_contents($dbinfoFile);
$contents = $addInfo.$contents;
$fp = fopen($dbinfoFile,"w");
fwrite($fp,$contents);
fclose($fp);

Use \$DB_NAME

 

Edit: see Variable parsing in double quoted strings in the PHP manual

wooo! thank you both for your excellent help 

[Imaulle]

okay new question lol. How would I get just the IP from the URL ?

[Imaulle]

oh cool I think I got it!

 

$getURL = $_SERVER['SERVER_ADDR'];
