PHP code for writing txt files

In addition, the windows line break is "rn" and the linux line break is "n"
The php ip record function is $ _ SERVER ["REMOTE_ADDR"]

PHP obtains the current time function date ("Y-m-d H: I: s", time ())

PHP functions for obtaining the origin site $ _ SERVER ['http _ referer'] must first determine whether it is null, that is, use isset to determine, for example, if we type a URL directly from the browser, there will be no URL record. The final code is very simple, as shown below:

The code is as follows:	Copy code
$ Ip = $ _ SERVER ["REMOTE_ADDR"]; $ Time = date ("Y-m-d H: I: s", time ()); $ From = ''; If (isset ($ _ SERVER ['http _ referer']) { $ From = $ _ SERVER ['http _ referer']; } $ Myfile = 'wtndata/statistic.txt '; $ Str = "ip = '". $ ip. "' from = '". $ from. "'Time ='". $ time. "'RN "; $ File_pointer = fopen ($ myfile, ""); Fwrite ($ file_pointer, $ str ); Fclose ($ file_pointer );
