[RESOLVED] Need help with text file processing

jkurrle

I'm normally a MySQL guy, so dealing with a text file is foreign to me. What I need to do is read a text file on a line by line basis. Each line is a delimited series of entries, in the same order.

Apparently, what I need to do is load the text file with a file() function, so each line is an item in the array. From there, I array_unshift() the first item off the array, explode() it, and parse out what data I need. That much I understand.

What I don't know is how to identify the last line in my file array. Can I use feof() somehow to do this? What test do I use in my while() loop if I can't use feof()?

Any assistance would be appreciated.

Why do you need the last item in the array? The while() loop will automatically stop when it reaches teh end of the array.

But [man]count/man will count the number of items in the array (counting starting at 1, array keys start at 0). Then you can just say if [man]count/man-1 == current_position, then you're on the last one.

Well, when running a while() loop, you need a condition. When I run my MySQL while loops, it looks something like this:

while ($row=mysql_fetch_array($result,MYSQL_ASSOC))
{
//process each item in the loop
}

What do I use for my condition in my text editing while() loop?

Also, am I correct in that if I find the line I need, I can use "break" to quit executing the loop?

Anyone out there who can help? Anyone?

$lines = file ($filename);

foreach ($lines as $line) {
    explode ($line).....
}

Thanks! That's what I needed. I'm so used to using for() or while(), I completely forgot foreach().
