I don't know what you mean by that but since you are using fgetcsv() then each line of the file should have columns separated by '~'. If that is the case, try:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>Untitled Document</title> 
</head> 

<?php 
	$namefile = 'pilots.txt';  
	$OUTFILE = fopen($namefile, 'r') or die("Can't open $namefile for read");
	if($OUTFILE!==FALSE)
	{
		echo PHP_EOL.'<table><tbody>';
		while( ($row=fgetcsv($OUTFILE,1024,'~'))!==FALSE )
		{
			echo PHP_EOL.'<tr><td>'.implode('</td><td>',$row).'</td></tr>';
		}
		echo PHP_EOL.'<tbody></table>';
		fclose ($OUTFILE);
     }
?>

Assuming that parameters.txt has the following two lines of Input:
Sport
model~price

Try:

<?php  

//then use the above within the 
$temp_name = $_FILES['UploadedFile']['tmp_name'];  
// check to see if file uploaded, using the super-global array $_FILES  
if (isset($_FILES['UploadedFile']['tmp_name']))  
{


	# $_FILES['fieldname']['name'] gives the uploaded file name
	print ("<p>");  
	$fil_name = $_FILES['UploadedFile']['name'];  
	$namefile = $fil_name;   
	$OUTFILE = fopen($namefile, 'r') or die("Can't open $namefile for read");


	//read the entire file into an array
	$params=file('parameters.txt');

	//after this $type will have "SPORT"
	$type=strtoupper($params[0]);

	//after this $columns[0] will have "MODEL" && $columns[1] will have "PRICE"
	$columns=explode('~',strtoupper($params[1]));

	//read the first line of the csv
	$data = fgetcsv($OUTFILE,1000, "~")
	
	//now find which column corresponds to "TYPE"
	$typeIndex=array_search($type, $data);

	//now find out the column index for each of the columns specified in parameters.txt
	foreach($columns as $i=>$v)
	{
		if(FALSE==($columns[$i]=array_search($v, $data)) )
		{
			echo "Column $v does not seem to exist";
			unset($columns[$i]);
		}
	}

	echo('<table>'); 
	do{

if you change it FROM:
Sport
model~price

to:
SUV
make~price

it should STILL work!

At the end of line 37 I missed a semi-colon. Make sure you add it.

Here is what i need it to do now. Not sure the best way about doing this. I was thinking of taking foreach loop out and replacing with just a for loop but not sure. Also i am not sure how to read two files, if that iwas the best way to do it.

Need to inspect the first line of the file to determine what column names are available. Then will have to accept a list of desired column names as input. The file name and desired columns can be program arguments, or accepted via the user interface, or even read in from another text file.

For example your data file may look like this cars.txt file:

MAKE~MODEL~TYPE~PRICE
Toyota~Camry~Sedan~18000
Toyota~Tacoma~Truck~19000
Ford~Mustang~Sport~21000
Chevrolet~Corvette~Sport~48000
Ford~F150~Truck~25000
Toyota~Highlander~SUV~35000

And a parameters.txt file may look like this

cars
model~price

sajohnson05 0 Light Poster · Answer 3 · 2010-11-04T22:35:54+00:00

What do i need to change if there is different parameters in the parameters.txt file?

sajohnson05 0 Light Poster · Answer 4 · 2010-11-05T00:06:03+00:00

in line 40 of the code i am getting the error Parse error: syntax error, unexpected T_VARIABLE. Any help would be great.

sajohnson05 0 Light Poster · Answer 5 · 2010-11-05T02:33:13+00:00

It will run but i am getting that the column does not exist

hielo 65 Veteran Poster · Answer 6 · 2010-11-05T05:09:05+00:00

after line 28 put print_r($params); do you see the data you had in parameters.txt? If not, the most likely the path to your file is wrong.

sajohnson05 0 Light Poster · Answer 7 · 2010-11-06T07:28:55+00:00

This is what i get when i put the print_r in. Not sure why it wont read
Array ( [0] => Car [1] => model~price ) Column PRICE does not seem to exist

hielo 65 Veteran Poster · Answer 8 · 2010-11-06T10:12:11+00:00

are you sure that the FIRST line in cars.txt has:
MAKE~MODEL~TYPE~PRICE

(all in upper case)?

Also, try changing: $columns=explode('~',strtoupper($params[1])); to: $columns=explode('~',strtoupper(trim($params[1])));

sajohnson05 0 Light Poster · Answer 9 · 2010-11-08T21:25:50+00:00

Now i am just getting this Array ( [0] => Car [1] => MODEL~PRICE )

And here is my Car File
MAKE~MODEL~TYPE~PRICE
Toyota~Camry~Sedan~18000
Toyota~Tacoma~Truck~19000
Ford~Mustang~Sport~21000
Chevrolet~Corvette~Sport~48000
Ford~F150~Truck~25000
Toyota~Highlander~SUV~35000

and parameters file
Car
MODEL~PRICE

sajohnson05 0 Light Poster · Answer 10 · 2010-11-09T19:50:59+00:00

and parameters file
Car
MODEL~PRICE

You cannot have Car on the first line and expect to have a result because if you look closer at Cars.txt NO record has "Car" listed under ANY of the columns. You need to be more explicit. So instead of "Car" use "Truck" since "Truck" DOES appear in the TYPE column.

Additionally, you also need to specify in WHICH column to look for "Truck". So use this as your parameters.txt file:

Type:truck
MODEL~PRICE

and use the following code instead:

	$filename = dirname(__FILE__).'/'.$_FILES['UploadedFile']['name']; 
	move_uploaded_file($_FILES['UploadedFile']['tmp_name'], $filename);
