This article mainly introduces the method of obtaining detailed data of flash size in PHP, including related usage skills of PHP getimagesize function. Friends in need can refer to it. I hope to be helpful.

The details are as follows:

Sometimes our website needs to obtain the size information of the flash file. PHP has a built-in function to achieve this. This function is getimagesize, which can return the size and file type of the image. An array of.

If you still want to get the size information of the flash file by parsing the header information of the swf file, then it is really a bit far, because starting from PHP 4, the getimagesize function has been built-in to do this. , its function determines the size of any GIF, JPG, PNG, SWF, SWC, PSD, TIFF, BMP, IFF, JP2, JPX, JB2, JPC, XBM or WBMP image file and returns the dimensions of the image as well as the file type and an available The height/width text string in the IMG tag in an ordinary HTML file, and starting from PHP 4.0.5, the parameter is also supported to be a url, for example:

$url="http://php.cn/images/srpr/logo4w.png";
print_r(getimagesize($url));

The output result is:

Array
(
  [0] => 550
  [1] => 190
  [2] => 3
  [3] => width="550" height="190"
  [bits] => 8
  [mime] => image/png
)

Let's look at another example of getting the flash file size:

$url="http://php.cn/static/api/data/e69b9944a2ce0afc9890f85f10dbcfc3.swf";
print_r(getimagesize($url));

The output results are as follows:

Array
(
  [0] => 540
  [1] => 250
  [2] => 13
  [3] => width="540" height="250"
  [mime] => application/x-shockwave-flash
)

I feel that getimagesize is still very powerful, and files of various image types can be operated.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4.
