Comment on Symfony2 and Doctrine2 Product & Images Mapping Not Efficient for Administration by Adam

Aayush,

Any update on your progress with this problem? I have a similar issue with "Listings" and "Images". First, properly structuring the Doctrine relationships, and then within the form (similar to you).

Each "Listing" may have multiple "Images".

Can you share any information that helped you in your case?

mysql_insert_id (and all mysql_ functions) is deprecated.

Comment on why is PHP hanging, when a bash call forks by Frosty Z

Maybe create another HTTP process by using an Ajax call to another PHP script, which task will be to launch asynchronously your sleep 30 command, or whatever you want, on the server.

Comment on Is there a difference between i==0 and 0==i? [closed] by Pierre

Pierre — Sun, 20 May 2012 20:53:15 +0000

no difference, some people prefer the second one to catch the common mistake of doing assignment (=) instead of equality test (==)

0 = i would fail at compilation

Comment on Removing URL Extensions by Boyd

You need to use HTACCESS mod_rewrite for this.

Roughly:

Create .htaccess (exact, only an extension without filename) in the root of your website

Please this code in it:

RewriteEngine On
RewriteBase /
RewriteRule /(.*?)$ /$1.php

Comment on RESTful webservice architecture and tokens by Michal

Michal — Sun, 20 May 2012 20:31:22 +0000

You can set up for example the header to pass username and password and then read them and validate on server. You could add some api secret key. For example:

//pseudocode
$request->Headers["X-Auth-User"] = $user;
$request->Headers["X-Auth-Key"] = $key;
$request->send(); //curl for example

Then you can set up additional firewall to handle authenticaton on serv via securitybundle.

Comment on Security between Android and PHP webservice by tasomaniac

I have solved my problem. What i need is to do signature verification on the server side. I just need to send the signature and the signed data to my server.
No one can trick these data. They are coming directly from google.
Once the signature verification is complete I just added the user to my mysql table.
