Why doesn't this work? - I have a simple file (symbols.dat) containing one stock symbol per line. Example: AMD INTC MSFT AAPL I want to take the contents of that file, put it into an array and turn it into a single string, separated by "+". Example: $symbolfile = array("data/symbols.dat"); sort($symbolfile); $symbols = implode('+', $symbolfile); The final result(string) should like: AMD+MSFT+INTC+AAPL+ If I skip the file, and just declare the array in the actual php script, everything works fine. When I try and pull it from the file, nothing is returned... not even an error. I'm sure the proper permissions are in place and the file definately exists. I tried opening the file in advance, using fopen, though that didn't seem to make a difference either. Any ideas? Thanks in advance.

correction, instead of: $symbolfile = array("data/symbols.dat"); I'm using: $symbolfile = file("data/symbols.dat"); Although, if I echo it out, it appears to work ok. It must be a problem with another part of my script. I'm using the string in a URL http://www.example.csv$symbol Again, when I declare the entire array and its contents within the script, it works fine.

I've managed a workaround by simply separating each symbol by commas, instead of new lines. However, now it appears I've lost the ability to sort the array.

This was resolved over at phpfreaks.com. It turns out that there was in fact a space between each symbol and "+" marker; I assume from the file. ex. AMD +IBM +SIRI +MSFT +DELL The code below took care of it. $arr = file('data/symbols.dat'); sort($arr); foreach($arr as $k=>$v){ $arr[$k]=trim($v); } $sym = implode('+', $arr);
