error handling

[dzoddi]

Hi

I'm simulating a memory error

I set the limit to 1 Mbyte so when this code is executed an error should appear

ini_set("memory_limit","1M");
...
echo("before");
$img = @imagecreatefromjpeg($tsrc);
echo("after");
header("location: [url]http://...[/url]");

When I run the script the result is the text "before", it seems that the execution is blocked at $img = @imagecreatefromjpeg($tsrc);

Do you have any suggestions? any missing configuration?

P.S. how can I get help online on @? what exactly does it do?

Thanks

the @ says "suppress any errors". take out the @ and you will probably get the error you're looking for.

try looking up 'error handling' at php.net? that might tell you more.

I've taken out the @ but the script doesn't run after this line
$img = @imagecreatefromjpeg($tsrc);

[sneakyimp]

this line:
$img = @imagecreatefromjpeg($tsrc);

still has an "@" in it. did you take it out or not? try changing that line to this:

$img = imagecreatefromjpeg($tsrc);

Here are my tests

********Test1
result of this script is a white page, "error" is not displayed, the same with error_reporting set to 0
ini_set("memory_limit","1M");
ini_set("error_reporting",E_ALL);
ini_set("display_errors",1);
ini_set("track_errors",true);
$img = @imagecreatefromjpeg("image source");
if (!$img) {
echo "error";
}

********Test2
result of this script is
Fatal error: Allowed memory size of 1048576 bytes exhausted (tried to allocate 8192 bytes)

ini_set("memory_limit","1M");
ini_set("error_reporting",E_ALL);
ini_set("display_errors",1);
ini_set("track_errors",true);
$img = imagecreatefromjpeg("image source");
if (!$img) {
echo "error";
}

********Test3
result of this script is a white page, "error" is not displayed
ini_set("memory_limit","0M");
ini_set("error_reporting",0);
ini_set("display_errors",1);
ini_set("track_errors",true);
$img = imagecreatefromjpeg("image source");
if (!$img) {
echo "error";
}
