Thanks Jcbones.
But what if I wanted to call the contents of a line from the file again.
Being out side of the for statment. How would I do this?
Could I make the statment $line[0]; to return the 1 from the file?
For example if the array was coded like this then I would be able to call elements of the array by the code
echo $numbers[0];
<?php
$numbers = array('10', '9', '8', '7', '6', '5', '4', '3', '2', '1');
if (file_exists("array.txt")) echo "File exists";
$fh = fopen("array.txt", 'r') or
die("File Does not exist");
$line = fgets($fh);
$numbers[1] = $line;
$line = fgets($fh);
$numbers[0] = $line;
fclose($fh);
echo "<br />";
echo $numbers[1];
echo "<br />";
echo $numbers[0];
?>

test file
The contents are
1
2
3
4
I need to read the file into an array then access the information latter.
For instance if I wanted to call the "2" again.
echo $myArray[1]; // this needs to call the 2nd spot in the array.
So I think that I need to use a for loop to store each line of the .txt file into an array index.

This script isnt working. Below the script is the out put when the file is run. Line 0 of the array should be 1 sence that is the first character in the .txt file.
<?php $line_of_text = file('ArrayTestFile.txt'); foreach($line_of_text as $lineNumber => $line) { $line_parts = explode(';',$line); echo 'Line ' . $lineNumber . ' of the array is <br /> ' . implode('<br /> ',$line_parts); } echo '<br /><br />You have reached the end of the file!'; ?>Line 0 of the array is
ArrayTestFile.txtArrayTestFile.txtArrayTestFile.t xtArrayTestFile.txtArrayTestFile.txtArrayTestFile .txt
You have reached the end of the file!

Then Should I not be able to do this?
<?php $file_handle = fopen("ArrayTestFile.txt", "rb"); $line_of_text = fgets($file_handle); $parts = explode(';', $line_of_text); print $parts[0] ." ". $parts[1]." ". $parts[2]." ". $parts[3]." ". $parts[4]." ". $parts[5] ; fclose($file_handle); ?>This is the output of the above code

Thanks pika.
If I were to do this though $array = file('ArrayTestFile.txt');
How would I then access each piece of the array?
$array[o]; //would this access the first carracter that is read from the file; meaning 1.

I need to read a .txt file into an array. I also need to beable to call on the parts of the arrray later.
I though that the best way to do this was to use a for loop and assign a $varable to each line of the .txt file that is being read.
