[PHP] Possible to check quality / compression of a JPEG ?
Hello: Is it possible with PHP to check at what quality/compression a JPEG file has been saved? I.e. I have dummy.jpg that I got from somewhere else and I want to know with what quality it was saved. The second Note of the User Contributed Notes on the PHP manual regarding the function imagejpeg (http://www.php.net/manual/en/function.imagejpeg.php) mentions such a code, and the user hints that he/she is able to read the quality of a jpeg, but there is no code given (I have tried contacting the user but the comment is quite old): == If you call imagecreatefromjpeg and load a jpeg with 75% quality and output it with imagejpeg u can specify the new quality for e.g. 90% and u can increase quality, but output will look like 75% quality picture with the only difference that the new pic is bigger. So u should check the source quality before u alter output quality. In most cases a quality of 75% is sufficient. For previews i use 50%. But i make a check if source quality is lower than my personal output quality, i will not chance source quality ! Hope that helps your Webserver and keeps the traffic low :-) == Regards, Juan Antonio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Connect to oracle on another host
Hi! I've been writing PHP scripts for a long time but never needed to get data from an Oracle database. Till now. Can somebody give me a hand? The Oracle database is running on another server. The information I have been given is: host (e.g. somewhere.somewhere.com) username (e.g. USER_NAME) pw (e.g. MY_PW) databse : PROD Function: F_CLAVE_SI_NO(loginnr) Basically what I need to do is contact this databsae, execute the function F_CLAVE_SI_NO($myloginnr), and get the results. The function F_CLAVE_SI_NO is a function from the Oractle database itself; it is no one written in PHP. Thank you for your help!

[PHP] Date functions Unic Epoch
Hi! Say, has anybody re-written the date funtions so they work with any date and not be crippled by the unix timestamp range limit? I am looking for a function which will do the equivalent of date(w,mktime(0,0,0,8,30,1934)) but that will actually *work*. Does anybody know a way to return which day of the week (0-7) it is for dates outside the unix timestamp range? I wish this stuff would be build into PHP.
