Request #51063 Add getimagesizefromstring
Submitted: 2010-02-16 21:54 UTC Modified: 2010-05-05 15:40 UTC

Description:
------------
It would be nice to be able to pass in a string to getimagesize.

Here is a patch that takes the original getimagesize function and turns it into php_getimagesize_from_stream.  Then getimagesize and a new function getimagesizefromstring can use the function once a stream is created.

http://www.brianfrance.com/software/php/getimagesizefromstring.diff



Reproduce code:
---------------
<?PHP
$img = 'test.gif';

var_dump(getimagesize($img));

$data = file_get_contents($img);

var_dump(getimagesizefromstring($data));
?>

Will apply it shortly after review (probably this WE). However it looks good already, thanks :)

Patch looks good except for one thing, that is the parameter parsing. You should 
use something along the lines of:

char *file;
int file_len;
HashTable *ht;

if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMS_CC, "s|H", &file, &file_len, 
&ht) == FAILURE)

The old (and deprecated) way of first doing a switch and use 
zend_get_parameters*() should be avoided.

Else good work on the patch ;)

Applied a slightly cleaner patch.
