Subject: [PHP] very weird PHP behaviour...
I don't know what it is... but PHP is acting very weird today... or I am
becoming crazy... can anyone tell me which one?
I have this function:
function
Upload($source_file,$source_filename,$dest_dir,$allowed_types=array())
{
global $upload_errmsg;
if( count($allowed_types) )
{
$file_ext=ArquivoExt($source_filename);
$ext_found=in_array($file_ext,$allowed_types);
//die("source=$source_filename");
//var_dump($ext_found);
//die;
if( !$ext_found )
{
$upload_errmsg="O arquivo \"$source_filename\" não está entre os tipos
autorizados";
//die("errmsg=$upload_errmsg");
return false;
}
}
... some more code here ..
return true;
}
the first crazy behaviour is... I use a test file called something.jpg,
ArquivoExt() returns me the extension of a given filename, in this case
"jpg". $allowed_types contains "gif","jpg" and "png" so that in_array()
should return true... and it does... but get this... if I uncomment that
var_dump() guess what it outputs?
bool(true) bool(false)
very weird... how can one var_dump() call gives me two outputs?
This double output doesn't occur if I uncomment the "die" after the
var_dump(). It only outputs bool(true) in that case.
Now for the second weird behaviour... since no matter what, $ext_found will
always be false (due to the previous weirdness) it will always enter the
IF... but the weird thing is when the caller of Upload() prints
$upload_errmsg it only outputs:
O arquivo "" não está entre os tipos autorizados
where is the filename? I've checked it tons of times... If I uncomment the
second die, right after the $upload_errmsg assignment, it outputs ok, with
the filename.
Now, can someone explain me this VERY WEIRD behaviour??
