‘Many countries, or even parts of countries, adopt daylight saving time (DST, also known as “Summer Time”) during part of the year. This typically involves advancing clocks by an hour near the start of spring and adjusting back in autumn (“spring” forward, “fall” back).’ (see Wikipedia) Now I will demonstrate how we can convert a [...]

I tried moving all my databases from MySQL 4.1 to MySQL 5.1 on Windows and since I had some InnoDB tables I could not just copy the data files between MySQL Server versions (from C:\Documents and Settings\All Users\Application Data\MySQL\MySQL 4.1\data\ to C:\Documents and Settings\All Users\Application Data\MySQL\MySQL 5.1\data\). So, after I exported the data from the [...]
This happens because of output_buffering is on. In order to turn off output buffering modify php.ini if you have access and set: output_buffering = Off or add in the local directory a .htaccess file containing this line: php_value output_buffering Off # or 0
This error occurs on any operating system (windows, linux). The problem is that instead of getting a sql file with the database data you get a empty (0 kb.) file.

I wanted to send an email that only contained an attachment as follows: $headers = “MIME-Version: 1.0\r\n”; $headers .= “To: <”.$to_email.”>\r\n”; $headers .= “From: “.$from_name.” <”.$from_email.”>”; $random_hash = md5(date(‘r’, time())); // add boundary string and mime type specification $headers .= “\r\nContent-Type: multipart/mixed; boundary=\”PHP-mixed-”.$random_hash.”\”"; // read the atachment file contents from a string previously formed, // [...]
Problem: Using specific characters from European languages like Romanian, Bulgarian, Czech and so on (usually the ones without support in ISO 8859-1) rises errors when displaying the content in browsers turning special characters in unrecognizable ones. My fix for this problem is using UTF-8 character set encoding for every page of the website and the [...]
I could not receive a failure notice when sending email to an email address that does not exist ($to_address), using this code: $subject = “Email subject”; $message = “line1\r\nline2\r\nline3″; $headers = “MIME-Version: 1.0\r\n”; $headers .= “Content-type: text/plain; charset=iso-8859-1\r\n”; $headers .= “To: <$to_email>\r\n”; $headers .= “From: Me <$my_email_address>\r\n”; $headers .= “Return-Path: <$my_return_email_address>r\n”; mail($to_email, $subject, $message, $headers); [...]
