Hi Manjunath,
The fopen() function is used to open files in PHP.
The first parameter of this function contains the name of the file to be opened and the second parameter specifies in which mode the file should be opened:
<html>
<body>
<?php
$file=fopen("welcome.txt","r");
?>
</body>
</html>
The file may be opened in one of the following modes:
Modes Description
r Read only. Starts at the beginning of the file
r+ Read/Write. Starts at the beginning of the file
w Write only. Opens and clears the contents of file; or creates a new file if it doesn't exist
w+ Read/Write. Opens and clears the contents of file; or creates a new file if it doesn't exist
a Append. Opens and writes to the end of the file or creates a new file if it doesn't exist
a+ Read/Append. Preserves file content by writing to the end of the file
x Write only. Creates a new file. Returns FALSE and an error if file already exists
x+ Read/Write. Creates a new file. Returns FALSE and an error if file already exists
few times both with and without the static keyword to see the effect it has.
