Re: [PHP] imagejpeg and downloading images
READ the manual.
The snippet is correct but if you want to take advantage of the saving
features of this function follow the function information at the top of
the page. Jumping straight to the user snippets is a mistake as they
are user contributed and may not document the whole function.
int imagejpeg ( resource image [, string filename [, int quality]])
imagejpeg($im,'myfile.jpg',80);

Hi All,
I'm using the following code to try to download images automatically from a
directory:
header('Content-Type: image/jpeg');
$im = imagecreatefromjpeg(001_SM77GR.jpg);
imagejpeg($im,'',85);
imagedestroy($im);
I copied this code from PHP.net. However, when I run the above code, it
doesn't download the image, it just shows the image in the browser. I'm
using IE 6 for my browser.
How I get PHP to download this image?
Thanks!

Re: [PHP] dynamic/multidimensional arrays in classes
$this-$arr[]
should be
$this-arr[]
You are using a variable defined within the class - since it is a class variable you can reference it as you would anything else within the class, using '$this-'

$this-$arr[] = $value; // this is the line causing the error

I've also tried using count() to find out how many items are in $arr, but it
keeps saying that $r == 0... i.e.
function add_something( $value )
{
$r = count($arr);
/*
if( is_null( $r )
{
$r = 0;
}
*/
//print( $r );
$this-$arr[$r] = $value;
}
I've tried this both with without the commented section still $r = 0
even if you use '$class-add_something(my value);' 50 times. I'm guessing
once this problem is solved it will work for multidimensional arrays as
well?

Re: [PHP] require_once adds a 1
The '1' is received simply because your requirement clause echoed the result to the page. include, require and include_once all return boolean results of 1 or 0 which indicates a successful loading of said include. If you want to suppress the output of an include use ob_ methods which prevent output the stdout. Simply putting 'include_once(anyfile.php)' will output whatever processes occur within that include. Putting the echo statement will additionally output the status of the include operation.

[Fwd: Re: [PHP] error while reading google-search-results]
Welcome to a mine field of problems :-)
1. The url you have entered is invalid. Thats a good first check to
make usually. Try /search?q=test to get that bit sorted.
2. Google prevents known useragents from accessing it's content as it
believes you are acting as a spider or a search engine stealing thier
content. To counter this you need to use a new url capturing method and
specifically set the name of the useragent. Use 'MSIE'. You can use
curl, lwp etc to do this kind of thing.
Curl is excellent, fast, highly configurable and execellent with secure
connections.
3. I suggest you don't do this - they prevent it for a reason.

RE: [PHP] user auth.. with mysql and cookies.. help
It's basically saying that you are outputing stuff to the browser before you
are setting the cookies which is a no go. All header requests (header()
setcookie()) must be run before any text is outputted.
Thus, the most common error is that after or before your php tags ? ? is
empty space, which to PHP is considered outputted text and you wont be able
to set any headers.
Other than that you might be setting cookies after you have echo'd templates
or some such.

RE: [PHP] Design Problem
I do it a different way - using IP's can be a bit of a bummer since they might change but often as not the hostnames dont. I detect spiders using the HTTP_USER_AGENT which identifies them either as say kitty once hourly, GoogleBot or Lycos or some such - most of the decent spiders use the user_agent var to identify themselves and you can display alternate info dependent on which spider it is. For the majority of the content stuff we do we steer clear of using long and difficult query strings since some (not all) search engines dont like them - We use the Apache Directive (Location or .htaccess Files) to run our stuff through what looks like a directory but is in fact just a script. - James -- W: www.londontown.com @: [EMAIL PROTECTED] -- -Original Message- From: Dani [mailto:[EMAIL PROTECTED]] Sent: 30 May 2002 15:18 To: James Holden Cc: [EMAIL PROTECTED] Subject: Re: [PHP] Design Problem Importance: High Thanks very much for the advice!
