PHP file Operation steps

Add Utf-8 in PHP:

1 header("content-type:text/html;charset= ' UTF-8 '");

File operation steps:

1. Create a file.txt folder in the same directory

2. Open File

1 $res = fopen("file.txt", "R"); // Open File path, open after is a resource, need further processing;//R is read-only meaning

3. Reading files

$str fread ($res, 300); // The second parameter is the length of the read (3 for each kanji) $str fread ($res,filesize("file.txt")); // filesize Read File size//above select one to display Echo $str;

4. Close the file

fclose ($res); // when you have finished reading, close the resource
