Php file writing

: This article mainly introduces PHP file writing. For more information about PHP tutorials, see. The file we want to operate is demo.txt.

One way is

$ File = fopen('demo.txt ', 'A ');

$ Content = 'xxxxxxxx ';

Fwrite ($ file, $ content );

Fclose ($ file );

Sometimes file writing is frequent to prevent writing failure. you can use

Flock ($ file, LOCK_EX );

Flock ($ file, LOCK_UN );

Another method

Use file_put_contents ();

If(file_exists('demo.txt ')){

$ Str = 'xxxxx ';
$ Fp = 'deno.txt ';
$ Fcontent = $ str. "\ r \ n ";
File_put_contents ($ fp, $ fcontent, FILE_APPEND | LOCK_EX );
} Else {
Echo 'The file does not exist ';
}

Note that the FILE path to be written is an absolute path, which can be obtained using _ FILE _.
