Basic PHP File Handling

Create a File

$my_file = 'file.txt'; $handle = fopen($my_file, 'w') or die('Cannot open file: '.$my_file); //implicitly creates file

Open a File

$my_file = 'file.txt'; $handle = fopen($my_file, 'w') or die('Cannot open file: '.$my_file); //open file for writing ('w','r','a')...

Read a File

$my_file = 'file.txt'; $handle = fopen($my_file, 'r'); $data = fread($handle,filesize($my_file));

Write to a File

$my_file = 'file.txt'; $handle = fopen($my_file, 'w') or die('Cannot open file: '.$my_file); $data = 'This is the data'; fwrite($handle, $data);

Append to a File

$my_file = 'file.txt'; $handle = fopen($my_file, 'a') or die('Cannot open file: '.$my_file); $data = 'New data line 1'; fwrite($handle, $data); $new_data = "\n".'New data line 2'; fwrite($handle, $new_data);

Close a File

$my_file = 'file.txt'; $handle = fopen($my_file, 'w') or die('Cannot open file: '.$my_file); //write some data here fclose($handle);

Delete a File

$my_file = 'file.txt'; unlink($my_file);
