Don't know, if this is a bug in the "getimagesize()" function.
The "php_getimagetype()" compares just 3 bytes of the 4-byte array.
Source code: /ext/standard/image.c
PHPAPI int php_getimagetype(php_stream * stream, char *filetype
TSRMLS_DC)
{
...
PHPAPI const char php_sig_psd[4] = {'8', 'B', 'P', 'S'};
...
} else if (!memcmp(filetype, php_sig_psd, 3)) {
...
}
