i know this is probably really simple... but im writing a fairly complicated download script which adds info to database depending on what is located in the downloads folder. im trying to get php to delete the row from the database if the file gets deleted from the directory. i have figured easiest way is to compare arrays. one database array and one directory array. thing is im not sure how to get a SQL column as an array. all i need is one column as an array. i know php can put rows into arrays but i coudltn work out columns.

thanks in advance,
Piercy

maybe something like

(Toggle Plain Text)

$results = mysql_query("SELECT theColumn FROM someTable WHERE someCondition", $db_link);
$thearray = new array();
while($row = mysql_fetch_array($results))
  array_push($thearray, $row[0])

this code is not tested in the least, but hopefully it's the right idea.

i tried that witha few adjustments here and there but it seemd to out put nothing at all. i had array printing in for debugging and even that aint working. plus the code originally outputted a table displaying all rows in the table. Also below is the whole of my code(twice one with you code one with my own that didnt work.) ALso should be output screen shots here:
http://www.1hess.com/piercy/images/

Heres the changes i made:

(Toggle Plain Text)

$results = mysql_query("SELECT `title` FROM c1hess_evo69.nuke_downloads_downloads");
$dbfilearray = new array();
while($row = mysql_fetch_array($results)) {
  array_push($dbfilearray, $row[0]);
  }

Code with your addition:

(Toggle Plain Text)

<?php
$server = 'eupub';
$etmain_cid = '10';
$etpub_cid = '13';
$jaymod_cid = '';
$etpro_cid = '';

$date = date('Y-m-d H-i-s');
$etmain = './etmain';
$etpub = './etpub';
$jaymod = './jaymod';

mysql_connect('localhost','***','*****');


////////////////////////////////////
////////////Etmain/////////////////
//////////////////////////////////




if($directory = opendir($etmain)){

$filearray = scandir($etmain);

print_r($filearray);
echo '<br><br>';

$results = mysql_query("SELECT `title` FROM c1hess_evo69.nuke_downloads_downloads");
$dbfilearray = new array();
while($row = mysql_fetch_array($results)) {
  array_push($dbfilearray, $row[0]);
  }

print_r($dbfilearray);
echo '<br><br>';
$diff = array_diff($filearray, $dbfilearray);
sort($diff);
$size = count($diff);

print_r($diff);
echo '<br><br>';
while ($num <= $size) {
$filedelete = $array[1];
mysql_query("DELETE * FROM c1hess_evo69.nuke_downloads_downloads WHERE `title`='$filedelete'");
array_splice($diff,1,1);
sort($diff);
$num++;
}
?>

My code before your addition:

(Toggle Plain Text)

<?php
$server = 'eupub';
$etmain_cid = '10';
$etpub_cid = '13';
$jaymod_cid = '';
$etpro_cid = '';

$date = date('Y-m-d H-i-s');
$etmain = './etmain';
$etpub = './etpub';
$jaymod = './jaymod';

mysql_connect('localhost','****','****');


////////////////////////////////////
////////////Etmain/////////////////
//////////////////////////////////




if($directory = opendir($etmain)){

$filearray = scandir($etmain);

print_r($filearray);
echo '<br><br>';
$dbrow = mysql_query("SELECT `title` FROM c1hess_evo69.nuke_downloads_downloads");
$dbfilearray = mysql_fetch_array($dbrow);

print_r($dbfilearray);
echo '<br><br>';
$diff = array_diff($filearray, $dbfilearray);
sort($diff);
$size = count($diff);

print_r($diff);
echo '<br><br>';
while ($num <= $size) {
$filedelete = $array[1];
mysql_query("DELETE * FROM c1hess_evo69.nuke_downloads_downloads WHERE `title`='$filedelete'");
array_splice($diff,1,1);
sort($diff);
$num++;
}

echo '<table border="1">Etmain additions:';
while($file = readdir($directory)) {


		if($file != "." && $file != ".." && $file != "index.html"){
		$stat = stat($etmain . '/' . $file);
		$filesize = $stat[7];
		$date = $stat[9];
		echo '<tr><td>' . $file . '</td><td>' . $filesize . '</td></tr>';


mysql_query("INSERT INTO c1hess_evo69.nuke_downloads_downloads (`cid`,`title`,`url`,`description`,`date`,`submitter`,`filesize`,`sub_ip`,`active`) VALUES ('$etmain_cid','$file','http://www.1hess.com/modsandmaps/$server/etmain/$file','Game File for [HESS] $server download to etmain.','$date','Piercy\'s directory bot','$filesize','$ip','1')");


}
}
echo '</table>';

closedir($directory);
}
?>

Ignore some of the excess variables. they bare there for easy change. (as i have to do this for 4 maybe more folders.).

I really appreciate your help,

this is a code excerpt I had laying around:

(Toggle Plain Text)

        $query = "SELECT contact FROM Contacts WHERE user = " . $this->id;
        $result = mysql_query($query, $this->link);
        if(!$result)
          throw new MySQLException("MySQL Error: " . mysql_error(), $query);
        $this->contactIDs = array();
        while($row = @mysql_fetch_array($result))
          array_push($this->contactIDs, $row[0]);

and it works fine. If I get a chance Friday, I'll try to look through your code again...

A friend has also geven me this to compare the database column with the folder. although his gives the same error as yours. Pretty sure its something in my code or maybe even server side.

(Toggle Plain Text)

while ($row = mysql_fetch_array($result, MYSQL_BOTH)) {
if (file_exists("path/to/files/".$row["files"])) {
echo "file ".$row["files"]." exists.<br>";
} else {
echo "file ".$row["files"]." does not exist, removing from db.<br>";
mysql_query("DELETE FROM downloads WHERE files=$row['files']");
}
}

Thanks for the help,
