2 things....

I have two little problems im hoping someone can help me with.
Im kinda new to php programming.

First problem.
I have the following in a script

$image_dir     = "photos/images";

however, I need to make it so it looks to a variable something like this..

$image_dir     = "photos/images/$VarName";

how would i format that?

Second problem.
I have a form which inserts data into a mysql database. The problem im having is that there is a URL fields. If some user enters a address like www.domainname.ext it tries to load from my website like http://www.mysitename.ext/www.domainname.ext so is it possible to have some type of formatting which will make it so it puts a http:// before the url if there isnt one?

Hi,
I really suggest that you should read the PHP manual because what you are asking now is in the first few pages 🙂

anyway It`s called concatination and this is how you do it.

$image_dir     = "photos/images/".$VarName;

In PHP "." (dot) is use to concatinate string values.

for the second question you are right put "http://" if there isnt one. 🙂

Good luck,

Regards,

Niroshan is right. However it can be done this way too:

	$VarName="voila!";	
	$image_dir= "photos/images/$VarName"; 	
	echo $image_dir;

gives

	photos/images/voila!

This is true for double quoted (" ") strings only. Single quoted strings do not expand variables:

	$VarName="voila!";	
	$image_dir= 'photos/images/$VarName'; 	
	echo $image_dir;

gives the expected

	photos/images/$VarName

Pitfall - in a case like this

	$var="tball supporters ";
	echo "[COLOR=DarkRed]foo$varbar[/COLOR]";

It is not clear where the variable ends, so one needs to indicate it explicitly thus:

	$var='tball supporters ';
	echo "[COLOR=DarkGreen]foo${var}bar[/COLOR]";

So, if the character after the variable could be part of a var name, use curly brackets.

I see u got the answer for your first question and I'll give u an example for your second question:

if(strstr($url,'http://')===false) $url = "http://{$url}";

Have fun coding. 😃
