An endless loop

[Dave Kelly]

This is a continuation of a previous thread:"Display ing text with
include file." This is the PHP include file.

I have about googled myself out on this one. If I have found what it is
I seek , I don't recognize it.

==========#
<?php
$data = file("outing.1. php");
foreach ($data as $line) {
$line = explode("_", $line);
print $line['0'];
}

?>
============#
This code does exactly as expected. It prints to the screen the first
element of the array.

The array is of unknown length. I need to print to the screen all
elements. I have been able to do this with: for loops, while loops, do
loops, and some if statements, the problem is stopping when it reached
an empty element.

Even if I chose an arbitrary number to stop at, it would print the
elements and the balance in error lines.

Anybody have suggestions on how to stop the endless loop?

TIA
Dave

The answer lies in your own code: foreach($line as $token) print $token;

That looks strange to me.
You use an associative array notation, when you clearly need a normal index.
$line is an array.
$line[0] contains the first element.
$line[1] contains the second element.
etc

I don't uderstand why you use '0' as index instead of a plain 0.
I am surprised this works at all. ???
Is PHP converting the string '0' to integer 0?
