Catch warnings

[Yeray Garcia]

Hi,

I'm using php to delete, rename, copy... some files. Sometimes php has
no permissions to do these operations, so the unlink(), rename(),
copy(), ... methods return a warning and send it to the browser.

What I'd like to do is to get these warning messages and save them in a
variable to print them somewhere else later so that it look nicer.

With the @ before the methods I can ignore warnings/errors but that's
not exactly what I want.

For example, when mysql returns an error, I can get it with the
mysql_error() method.

Has anyone an idea, how could I do this?

Thanks
Yeray

========
<?php

$old_track = ini_set('track_ errors', '1');

if (!@unlink('no_f ile')) {
echo $php_errormsg, "\n";
}

if (!@copy('no_fil e', 'some_file')) {
echo $php_errormsg, "\n";
}

ini_set('track_ errors', $old_track);

?>
========


And the output is:

No such file or directory
failed to open stream: No such file or directory

Re: Catch warnings

That is exactly what I was looking for.
