Re: [PHP] mysql_query blocking
Daniel Kolbo wrote: Hello, When a MySQL table is locked a php call of mysql_query() that requires that table will hang as the request blocks at the MySQL server until the table is unlocked. Is there a way to stop a mysql_query from hanging (by setting a time limit)? Daniel I can understand you asking the question here, but I suspect that the answer may come better from a list who has people who are more expert in MySQL? Personally - with Firebird - this is not a problem that ever arises since 'locking' is not something one would normally do and has only appeared IN Firebird because people 'expect' that is how a database works. Even if using it would actually be wrong :) The problem is that the database is the problem rather than PHP, hence the questions about which type of tables you are using in MySQL. From my personal experience, it's the way that you are using the database that may be wrong if it relies on 'locking' to achieve something that is not properly managed IN the database. Any database can provide 'locking', if that is really required, by additional flagging in the database - if the database itself does not provide the function properly. Such as setting an 'edit' flag on a record showing who is changing it, which can then be used to advise that fact to other users. -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Image Type BMP @ "Save Image As" Dialog on IE
Nitsan Bin-Nun napsal(a): I have wrote a PHP script that serves JPEG images in smaller size, the resize is done using GD on-the-fly. I have noticed an interesting issue during the "save image as..." dialog on serveral internet explorer browsers, somehow, for some strange reason, the JPEG file is shown as BMP file. I don't know why this is happening, but I'm trying to make it save it as JPG file. In firefox or any other browser everything works like a charm. I have to mention that the JPG file is located in the HTML in the following format: I have also used mod_rewrite to serve the file with .jpg extension (I thought that the strange IE may not know how to recognize it..), the PHP file is sending the correct headers, I'm attaching an example for HTTP request & response for this resized image: GET /gallery-image-dolphinim-12450163853.

I have been working on it for a while but no luck. I personally don't have IE to test it but my customer have noticed it and brought it up to the table.

[PHP] Problems with an extension
So I am developing a custom extension and I am having a issue. I have a header file that I need included in the project. If I #include the header file everything compiles and makes just fine, but after restarting the web server the extension won't load. If I remove or comment out the #include of the header file everything still compiles and makes just fine, and after restarting the web server the extension is loaded just fine. Does anyone have any idea what would cause the extension to refuse to load with the header file included? -Eric -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Eric, Custom extensions programming is in C/C++ (as also indicated by your #include reference), which is beyond the scope of this list. Unfortunately, there is not an official dedicated list for extensions developers, but if it's not urgent, you can email me privately at danbr...@php.net and I'll see if I can help you out. -- daniel.br...@parasane.net || danbr...@php.net http://www.parasane.net/ || http://www.pilotpig.net/ Ask me about our fully-managed servers and proactive management clusters starting at just $200/mo.! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks Dan: I thought it might be beyond this list, but I figured it might be worth the shot. It is not urgent at all, so I will drop you a private message with a more detailed explanation and if you can help great, if not, I'll keep poking around at it. -Eric -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Socket error
Hey guys, getting an odd error here... The code involved: $master_socket = socket_create_listen($this->port); socket_bind($master_socket, '127.0.0.1', $this->port); socket_listen($master_socket); socket_set_option($master_socket, SOL_SOCKET, SO_REUSEADDR, 1); socket_set_nonblock($master_socket); And I'm getting: 'PHP Warning: socket_bind(): unable to bind address [22]: Invalid argument in /home/luke/talkserver/new/classes/server.php online 30' $this->port is valid, I've checked both this and that socket_create_listen seems to be executing correctly. I'm a bit lost on the error too it seems to be what the php.net manual says are the parameters? I'm trying to create a listening socket server that binds to a port on the local machine. Thanks in advance for any help! -- Luke Slater :O)
[PHP] Best way to reinstate radio-button states from database?
I have a webpage which allows people to log in and make selections with radio buttons and hit SUBMIT and saves the data from those radio buttons to a mySQL database. However, I'm finding that I also need the ability to allow a user to log back in at a later date (or even on a different computer), and pull up that survey again, with each of the 50-something radio-buttons back in the positions in which they were last saved. Surely there's a best-case-method for doing this type of thing (saving large numbers of radio-button-group settings to mySQL and pulling them back again later). Any advice is greatly appreciated. Perhaps there's a jQuery-way to retrieve all the radio-button group settings as an array and save it and pull it back again? Or perhaps a PHP-specific method - - - I'm fine with either. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What port are you trying to bind to?
