Compare 2 csv Files in PHP with better Result - php

Question

i found a very good PHP solution here for compareing 2 CSV Files.
The Only Problem is the Result Page..
index.php?f1=re1.csv&f2=re2.csv
<?php
//---- init
$strFileName1=isset($_REQUEST['f1'])?$_REQUEST['f1']:'';
$strFileName2=isset($_REQUEST['f2'])?$_REQUEST['f2']:'';
if ( !$strFileName1 ) { die("I need the first file (f1)"); }
if ( !$strFileName2 ) { die("I need the second file (f2)"); }
try {
$arrFile1 = parseData($strFileName1);
$arrFile2 = parseData($strFileName2);
} catch (Exception $e) {
die($e->getMessage());
}
$rowCount1=count($arrFile1);
$rowCount2=count($arrFile2);
$colCount1=count($arrFile1[0]);
$colCount2=count($arrFile2[0]);
$highestRowCount = $rowCount1>$rowCount2 ? $rowCount1:$rowCount2;
$highestColCount = $colCount1>$colCount2 ? $colCount1:$colCount2;
$row = 0;
$err = 0;
//---- code
echo "<h2>Vergleich $strFileName1 and $strFileName2</h2>";
echo "\n<table border=1>";
echo "\n<tr><th>Err<th>Tabelle<th>Row#<th>Col#<th>Data in $strFileName1<th>Data in $strFileName2";
while($row<$highestRowCount) {
if(!isset($arrFile1[$row])) {
echo "\n<tr><td>Row missing in $strFileName1<th>$row";
$err++;
} elseif(!isset($arrFile1[$row])) {
echo "\n<tr><td>Row missing in $strFileName2<th>$row";
$err++;
} else {
$col=0;
while($col<$highestColCount) {
if ( !isset($arrFile1[$row][$col]) ) {
echo "\n<tr><td>Data missing in $strFileName1<td>$row<td>$col<td><td>".htmlentities($arrFile2[$row][$col]);
$err++;
} elseif ( !isset($arrFile2[$row][$col]) ) {
echo "\n<tr><td>Data missing in $strFileName1<td>$row<td>$col<td>".htmlentities($arrFile1[$row][$col]) ."<td>";
$err++;
} elseif ( $arrFile1[$row][$col] != $arrFile2[$row][$col] ) {
echo "\n<tr><td>Data mismatch";
echo "<td>Tabelle <td>$row <td>$col";
echo "<td>".htmlentities($arrFile1[$row][$col]);
echo "<td>".htmlentities($arrFile2[$row][$col]);
$err++;
}
$col++;
}
}
$row++;
}
echo "</table>";
if ( !$err ) {
echo "<br/>\n<br/>\nThe two csv data files seem identical<br/>\n";
} else {
echo "<br/>\n<br/>\nThere are $err differences";
}
//---- functions
function parseData($strFilename) {
$arrParsed = array();
$handle = fopen($strFilename , "r");
if ($handle) {
while (!feof($handle)) {
$data = fgetcsv($handle , 0 , ',' , '"' );
if ( empty($data)) continue; //empty row
$arrParsed[]=$data;
}
fclose($handle);
} else {
throw new Exception("File read error at $strFilename");
}
return $arrParsed;
}
?>
The Result displays the Row# and Col# of the file..
but what i need is the Name of the Col..
This is how my CSV looks like:
ISO_COUNTRY_CODE,CNT_POSTAL_CODE,ORDER1_ADMIN_TYP_1112,ORDER2_ADMIN_TYP_1113,ORDER8_ADMIN_TYP_1119,BUILTUP_ID
AND,7,0,0,7,40
ARG,1970,25,0,514,4076
AUS,2612,9,0,10978,4597
AUT,2213,9,95,2354,10304
BEL,1148,3,11,589,3781
BGR,4507,28,0,264,5375
I want to see in which "ISO_COUNTRY_CODE" is the CNT_POSTAL_CODE wrong..
$rowname = $row; // here i want to see the RAW of the Table
"like AND or ARG etc"
$colname = $col; // here i want to see the COL of the Table
"like CNT_POSTAL_CODE
or ORDER1_ADMIN_TYP_1112 etc "
