PHP code for writing text file txt _php tutorial

PHP writes text file and C language very similar, with the function also consistent, read file with fopen, write file with fwrite, end with Fclose. Note that the new file is opened and written with the "W" identifier, the read file is identified with "R", and the original file continues to be written with the "a" identifier

, while the Windows line break is "RN", and the Linux newline character is "n"
PHP record IP function is $_server["REMOTE_ADDR"]

PHP Gets the current time function date ("Y-m-d h:i:s", Times ())

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, "a"); Fwrite ($file _pointer, $STR); Fclose ($file _pointer);
