PHP Implode File Question

[rjbearcan]

Can I not use a variable with implode such as
implode('', file('$url'));

as opposed to

implode('', file('http://www.example.com/'));

When I pass the variable, nothing comes up, yet if I pass the actual url, it works.

Yes, but you can't have it in single quotation marks. Either double quotation marks or none at all.

Strings [php.net]

Even when I add the double quotations or no quotations at all, nothing still comes up. The url is in the format:

http://example.com?a=$b

Have you echoed the $url variable to see if its populated?

[coopster]

There shouldn't be any difference. I am referring to the parsing of the '$url' which is not happening in the file() function because of the single quotation marks. Are we indeed discussing the same thing? Because it should work just as if you were keying the url into the file() function.

Dump the $url variable to your browser to make sure you have the url value there ...

I got it fixed. I was missing a semicolon from the previous line. Thanks for your help!
