[RESOLVED] I don't understand this error...

[s_shrum]

I am getting this message on line 6 (and line 12) of my code:

Warning: Cannot use a scalar value as an array in /data/webs/shrum.net/html/files.php on line 6

Here's the code:

<?php
function &main($aParams) {
	$aResults = &get_file_list($aParams['dir'], true);
	foreach ($aResults as $key => $row) {
		if ($aResults[$key]['size'] <= "1024") { 
			$aResults[$key]["size"] .= " bytes";
		} elseif ($aResults[$key]['size'] <= 1048576) {
			$aResults[$key]['size'] = round($aResults[$key]['size']/1024,1)." kb";
		} else {
			$aResults[$key]['size'] = round($aResults[$key]['size']/1048576,1)." mb";
		}
		$aResults[$key]['modified'] = date("Y-m-d G:i:s", $aResults[$key]['modified']);
		if (file_exists($_SERVER['DOCUMENT_ROOT'].$aResults[$key]['dir'].$aResults[$key]['base'].$aResults[$key]['ext'].".caption")) {
			$fp = fopen($_SERVER['DOCUMENT_ROOT'].$aResults[$key]['dir'].$aResults[$key]['base'].$aResults[$key]['ext'].".caption", 'r');
			$aResults[$key]['caption'] = @fread ($fp, filesize($_SERVER['DOCUMENT_ROOT'].$aResults[$key]['dir'].$aResults[$key]['base'].$aResults[$key]['ext'].".caption"));
			fclose ($fp);
		} else {
			$aResults[$filecount]['caption'] = $aResults[$key]['base'].$aResults[$key]['ext'];
		}
	}
	return $aResults;
}
?>

I don't see any problems syntax wise (I think)??? The script still works but it's generating the warnings.

TIA

I assume lines 6 and 12 of the document are not the same as lines 6 and 12 of this code snippet? Which lines specifically relate to the warnings? The warning you've received isn't a syntax problem, it's saying you're trying to do an operation on a scalar when an array is expected...

[s_shrum]

Nope...6 and 12 of the code snippet are the lines the warnings are being issued on.

This is a module that I'm writing for my content system; a plug-in.

[mrhappiness]

above the foreach:

echo '<pre>'.print_r($aResults, true).'</pre>';

post the result please (including any error messages)

Here's one of the array records:

Array
(
    [0] => Array
        (
            [dir] => /wallpapers/repository/movies/anime/GITS_SAC/
            [base] => GITS_SAC_D4-013
            [ext] => .jpg
            [type] => file
            [size] => 119630
            [modified] => 1107505537
            [age] => 17011183
            [filesize] => 116.8 kb
            [timestamp] => 2005-02-04 0:25:37
        ) 

I can't figure it out...I though about converting types: string vs int, syntax, etc.

I must be blind cuz I still can't see where the problem is in that line...I still have no idea why I'm still getting this message.

[bbreslauer]

Just a random thought....on line 6, size is enclosed in double quotes ("), though all the other times, it's enclosed in single quotes ('). Try changing that...

As for why it's happening on line 12, i'm not sure. Something that I occasionally do to figure out exactly where on a line the problem is is to split the line onto multiple lines. Since the end of a command is marked by a semicolon, opposed to using the end of the line, like FORTRAN. If you split the statement enough, you'll probably be able to figure out what the error is coming from.

[s_shrum]

I fixed it although I worked around it. Here's the new working code that uses a secondary array and then merges them

<?php
function &main(&$aParams) {
	$aResults = get_file_list($aParams['dir'], true);
	foreach ($aResults as $key => $row) {
		if ($aResults[$key]['size'] <= 1024) {
			$aTemp['filesize'] = $aResults[$key]['size']." bytes";
		} elseif ($aResults[$key]['size'] <= 1048576) {
			$aTemp['filesize'] = round($aResults[$key]['size']/1024,1)." kb";
		} else {
			$aTemp['filesize'] = round($aResults[$key]['size']/1048576,1)." mb";
		}
		$aTemp['timestamp'] = date("Y-m-d G:i:s", $aResults[$key]['modified']);
		if (file_exists($_SERVER['DOCUMENT_ROOT'].$aResults[$key]['dir'].$aResults[$key]['base'].$aResults[$key]['ext'].".caption")) {
			$fp = fopen($_SERVER['DOCUMENT_ROOT'].$aResults[$key]['dir'].$aResults[$key]['base'].$aResults[$key]['ext'].".caption", 'r');
			$aTemp['caption'] = @fread ($fp, filesize($_SERVER['DOCUMENT_ROOT'].$aResults[$key]['dir'].$aResults[$key]['base'].$aResults[$key]['ext'].".caption"));
			fclose ($fp);
		} else {
			$aTemp['caption'] = $aResults[$key]['base'].$aResults[$key]['ext'];
		}
		$aResults[$key] = array_merge($aResults[$key], $aTemp);		
	}
	return $aResults;
}
?>

Still can't figure out why it was triggering the warnings.

Oh well.

Thanks to everyone that chimed in.
