PHP File Write

The fwrite() function is a main function that is used to write something into files.

This function returns the number of bytes written, or FALSE on failure.

Syntax

fwrite($file,$string,$length)

$file – Required. Specifies the open file to write to
$string – Required. Specifies the string to write to the open file
$length – Optional. Specifies the maximum number of bytes to write

Example:

Before we can write information to our test file we have to use the function fopen to open the file for writing.

$myFile = “testfile.txt”;
$fh = fopen($myFile, ‘w’) or die(“can’t open file”);
$stringData = “First comment – write into text file”;
fclose($fh);

The $fh variable contains the file handle for testfile.txt. The file handle knows the current file pointer, which for writing, starts out at the beginning of the file.

Now open the testfile.txt.
