nba2k online dunk skills PHP collection experience skills

1. Get the source code of the remote file (file_get_contents or use fopen).
2. Analyze the code to get the content you want (use regular matching here, usually to get paging).
3. Download and store the content obtained from the root.
　The second step here may need to be repeated several times. For example, we need to analyze the paging address first, and then analyze the content of the inner page to get what we want.
　 Code:
I remembered that I posted part of the code before. Today I will simply post it here
Copy the PHP content to the clipboard
PHP code:
@$nl=file_get_contents($rs['url']); //Capture remote content
preg_match_all("/var url = "gameswf/(.*?).swf";/is",$nl,$connect);//Perform formal matching to get the content you want
mysql_query( "insert...insert database part");
　The above code is the code used for all collections. Of course, you can also use fope to do it. I personally like to use file_get_contents.
　Now I will share my method of downloading pictures to local flash, it is too simple with two lines of code
　 PHP code:

Copy code The code is as follows:

if(@copy($url,$newurl) ){
echo 'ok';
}

I have posted a picture download function on the forum before, and I will post it for everyone
*Local image function*/
function getimg($url,$filename){

　　/*Determine whether the url of the image is empty, if it is empty, stop the function*/ 　　if($url==""){ 　　　　return false ; 　　} 　　/*Get the extension of the image and store it in the variable $ext*/

　　$ext=strrchr($url,".");

　　/*Determine whether it is a legal image file*/
　if($ ext!=".gif" && $ext!=".jpg"){
　　　　return false;
　　}
　　/*Read the picture*/
　　$img=file_get_contents($url);
　　/*Open the specified file*

In fact, it is possible to fake the origin, but the collection cost of such a site is too high
　2. For sites that collect as quickly as possible, it is best to collect locally
　3. When collecting, there are many times when you can save part of the data into the database first, and then proceed to the next step. processing.
　4. You must handle errors when collecting. I usually skip it if the collection fails three times. In the past, I would often get stuck picking out a piece of content just because I couldn't pick it up.
　 5. You must make good judgment before entering the database, check the legality of the content, and filter unnecessary strings.
