[RESOLVED] compare 2 arrays

[jrough]

Is there an easy way to compare arrays? See the asterisks.
See the line with the asterisks.

I have an array of file names from a directory in $file.
All these files should have the first 11 column names.
They can have more than that but they have to have the first 11 column names.

foreach ($file as $val){
$hdrArray=("myfield1,myfield2,myfield3,myfield4,myfield5,myfield6,myfield7,myfield8,myfield9,myfield10,myfield11)
if (($fh = fopen($target_path, 'r+'))!== FALSE ){
    while (($res = fgets($fh, ",")) !== FALSE) {
    if ($res[1]==($hdrArray)==false){                      *******
        echo " <bold>The header in $file is wrong. \n</bold>";
        exit;}
    $sData= " ' ". implode( " ', ' ", $res). " ' ";
    $sData=htmlspecialchars($sData);
    }//end while
  $row++ ;
}//end if
fclose($fh);

thanks

foreach($arr1 as $x) {
  if (!in_array($x, $arr2)) {
    echo $x . ' is not in array #2<br>';
  }
}

Or this looks even easier: [man]array_diff[/man]

I thought about array-diff when you do array_diff does it matter the order of the values?
In other words since I am doing inserts I need the indexes to be continuous not just which values in array 1 are in array 2 I need to know that all the values are in array 2 in the same order as array1. maybe they don't need to be in the same order. I am doing an INSERT INTO (field1, field2, field3) VALUES(value1,value2,value3) so if htey are out of order it doesn't matter. Array_diff or the in_array doens't really matter.
thanks,

Try [man]array_diff_assoc[/man]. Perhaps you could test it yourself? I'm not sure exactly what you want.

Hi,
I can't test it myself. This brings up another question.
I can't seem to open the file on the server for reading?
fopen($handle) on the server is giving me a warning message that says permission denied.
This is on a Windows Server.
The directory with the text files in it is read only.
But doesn't fopen() work on a remote server as read only?
This is the part right before the foreach.
I don't understand why it can't read the files in the link directory?
if ($handle = opendir('link/')) {
echo "Directory handle: $handle\n";
while (false !== ($files = readdir($handle))) {
array_push($file,"$files");
echo "$files\n";

}

}
closedir($handle);

Why not?

[jrough]

I will test it tomorrow with the array_diff_assoc and array_diff but the problem is right now the script doesn't run because I'm getting a fopen() permission error.
Thanks for your help, you got me going good enough to figure it out.

Are you sure $target_path is defined in your script? Are you sure that your web server has the correct permissions to open that file?
