PHP & Flash

To upload/post large files through PHP, there are 2 methods. One is by setting the directives in php.ini file or using ini_set or set in .htaccess, and the other one is to use PHP's built-in FTP functionality.

1. Set in php.ini or through ini_set:

upload_max_filesize = 30M
post_max_filesize = 32M
max_input_time = 1800
max_execution_time = 1800

Someone said that you also need to set:

memory_limit = 96M

In .htaccess, set

php_value max_execution_time 600
php_value upload_max_filesize 501M
php_value post_max_size 501M

Exporting to Excel from PHP is usually done by creating tab-separated or comma-separated files. These types have language compatibility problems due to Excel's dumbness in using the right encoding to open them automatically. Unless the user's system fits with the encoding, otherwise there is a hell of steps to go through. To solve this problem, you can actually export the data in HTML table format and specify the right encoding to use in the header section. This does not only solve the problem, it also offers CSS style controls of data presentation. Much better than working with th

If you are using MySQL 4.0, you would probably notice that your special characters such as å Â are converted to a form like "&#2345."

In order to pass these characters using PHP into Flash, you need to use the following function to convert them back to UTF-8:

function unichr($dec) {
  if ($dec < 128) {
   $utf = chr($dec);
  } else if ($dec < 2048) {
   $utf = chr(192 + (($dec - ($dec % 64)) / 64));
   $utf .= chr(128 + ($dec % 64));
  } else {
   $utf = chr(224 + (($dec - ($dec % 4096)) / 4096));
   $utf .= chr(128 + ((($dec % 4096) - ($dec % 64)) / 64));
   $utf .= chr(128 + ($dec % 64));
  }
  return $utf;
}

If you have written a PHP application involving sending multilanguage headers, such as subject in Chinese, from in Japanese, etc.

You will probably notice that some mail clients such as Outlook does not translate these headers correctly.

The problem is that if these header fields are in different languages, proper encoding strings have to be prepended to it for mail clients to read them correctly. Furthermore, the string itself has to be base64 encoded. The following function will do the trick for you. BTW, you should only encode the "name" part of from and "subject" lines, do not encode anything else such as <email> fields.

the flash reads the output from php as Unicode encoding, and thus GB2312 characters were displayed as weird codes. to
solve this problem i found the following articles from the macromedia website:

Working with Multiple Languages

trick to use:

1. include system.useCodepage = true; in the first frame of the movie.

Condition: in order for this to work, the client’s operating system must use GB2312 encoding, otherwise the
string will still mess up. basically this statement tells flash player to use client’s operating system’s font encoding
instead of the default Unicode in flash player.
