This is often seen when people ask "I cannot connect to HTTPS site using cURL" or have the "SSL certificate problem, verify that the CA cert is OK" error with cURL. Ideally, you should set the SSL_VERIFYPEER value to true unless the server you are connecting to does not have a signed certificate. If you are sending confidential data, wouldn't you want to make sure you are connecting to the correct server? This guide will help you get the CA certificate from the remote server using Mozilla Firefox 6 and then use PHP with cURL to retrieve the information from the remote https server.]]> http://albertech.net/2011/10/guide-for-using-php-curl-with-https-requests-and-ca-certificate/feed/ 2 http://albertech.net/2011/09/quick-review-of-netbeans/ http://albertech.net/2011/09/quick-review-of-netbeans/#comments Sat, 17 Sep 2011 18:54:05 +0000 admin http://albertech.net/?p=782 http://albertech.net/2011/09/quick-review-of-netbeans/feed/ 0 http://albertech.net/2011/08/adding-captcha-to-squirrelmail/ http://albertech.net/2011/08/adding-captcha-to-squirrelmail/#comments Mon, 08 Aug 2011 21:01:06 +0000 admin http://albertech.net/?p=763 Here's a quick guide to enabling the CAPTCHA plugin in Squirrelmail.

If you have a site with heavy CPU and memory load in Apache, then nginx is a great choice. I recently made the switch to nginx and have noticed a reduction in CPU and memory usage.

  Web browsers are now following a standard for HTTP Access control to prevent client-side Cross Site scripting attacks.
  
  I tested this with Firefox and it simply blocks the request without any error messages. Google Chrome browser will error out with the following message if the access control origin is not set correctly on your PHP script. (woot!)
  
  "XMLHttpRequest cannot load [PHP URL].. Origin [JAVASCRIPT URL] is not allowed by Access-Control-Allow-Origin."
  
  For example, if the Javascript is hosted on example.com and your PHP app is on example.org. Below is the PHP script for fixing this error.

  • What are the number of tables in a MySQL database?
  • What are the number of rows in a MySQL database?
  • How much space is the MySQL database using up on the server?
  • How many tables there are in a MySQL server?
  • How many rows there are in a MySQL server?
  One of the quickest ways to find out MySQL reporting stats is using PHPMyAdmin. The software is usually installed on a number of servers by default, so its just a matter of locating where in the program to find this info.

  1. Remove the wp-content/blogs.php file as it is no longer supported in WordPress 3.0. It has been replaced with wp-includes/ms-files.php
  2. Locate the .htaccess file in the root directory
  3. Find the following line: [php]RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L][/php]
  4. Replace it with: [php]RewriteRule ^(.*/)?files/(.*) wp-includes/ms-files.php?file=$2 [L][/php]
  5. This should fix the problem with broken images/files not showing up in the WordPress MU blogs.

Evidently, the text format of the document had UTF characters, which caused CodeIgniter to error out when it tried to insert it to the database. The line had French characters (The ç in Français) My database fields by default are set to "latin1_swedish_ci" character set. The fix? I decided the best way to fix this was to set the Collation option for that specific field in the MySQL database to  "utf8_general_ci
