Help with Strings Functions

[Anon]

Hi,

I haven't been able to figure out how to check to see if a string is within another string.

Also, How do you trim specific text from the beginning and end of a string?

Last, but not least, the PHP code I am writing sends data to a webserver and recieves it. I'm having trouble recieving it. All the examples I have seen use something like:

while(!feof($fp)){
echo fgets($fp);
}

I know they may be mistakes, but I'm new, and don't have it in my head. The PHP page doesnt return anything, it justs gets stuck, but when I remove the while statement, and just leave fgets, it returns a line each time you call it.

Thanks for any help!

Use strpos()

I'm unclear on why/how you're using fgets() but the way the traditional file loop works is:

Open file then
While the EOF (end of file) character isn't read, Read some data.

Usually you specify how much data to read.
