Error handling

Anon

Does anyone know of, or have, a basic example error handling script for php? Or even a nice little tutorial?

I have seen how the @ operator works already, I am talking about error handling and how it works in php.

Any direction would be greatly appreciated.

Thanks!
Matt.

if you mean how PHP reports errors to the browser, you can use error_reporting();.

You can use:
0 - Fatals,
2 - Warnings,
4 - Parse Errors,
8 - Notices

and you add the ones you want to use and use that like thus: error_reporting(6) which will report Warnings and Parse Errors.

You can also use error_log() in a number of ways to send emails to you about an error, append to an error log file, etc. (see the manuals for details).

Sincerely,
Chad.

Is there a way to make it so that the errors don't show up on the page?

So that instead it just omits them?

Kind Regards,

Heather

Use "@" before the function call.

ex>
if( @copy('/temp','/dest')
{
//do something with file or whatever.
}
else
{
//report copying error or do something based on the error.
}

I have a function that prints all the directories and subdirectories and files. Some of the directories are locked and I can't get in them so I can't print to the screen what is in them and I can't change the permission on the directory either, so what I get is an error that says;

Warning: ChDir: Permission denied (errno 13) in

Here is my code:

<?php

$basedir = "/home/"; // Base directory

function listall($dir)
{
// Initialize temporary arrays for sorting
$dir_files = $dir_subdirs = array();

 // Print current directory
print( "<ul>");
print( "<li><b>$dir</b>\n");

 // Change to directory
chdir($dir);

 // Open directory;
$handle = @opendir($dir);
// or die( "Directory \"$dir\"not found.");

 // Loop through all directory entries, construct
 // two temporary arrays containing files and sub directories
while($entry = readdir($handle))
{
    if(is_dir($entry) && $entry !=  ".." && $entry !=  ".")
    {
        $dir_subdirs[] = $entry;
    }
    elseif($entry !=  ".." && $entry !=  ".")
    {
        $dir_files[] = $entry;
    }
}

 // Sort files and sub directories
sort($dir_files);
sort($dir_subdirs);

 // Print all files in the curent directory
for($i=0; $i<count($dir_files); $i++)
{
    print( "<li>$dir_files[$i]\n");
}

 // Traverse sub directories
for($i=0; $i<count($dir_subdirs); $i++)
{
    listall( "$dir$dir_subdirs[$i]/");
}
print( "</ul>");
 // Close directory
closedir($handle);

}
listall($basedir);
?>

so from what I can tell is that I would of calling the function like

listall($basedir);

instead I should do:

@listall($basedir); {
print (you can't get to this directory);
}

Thanks in advance for your help!
