PHP 5 File write or create
In this section we will learn how to write file data on server.
fwrite function is used to write the content of string into the file file specified by filepointer. It's takes two parameter first is file pointer and second is lenght or byte of content.
Syntax of fopen
int fwrite (int filepointer,string [, int length])
If the optional input parameter length is provided, writing will stop either after length characters have been written or after the end of string has been reached.
<?php $fh = fopen("ptutorial.txt","w") ; $u="Mr. John "; fwrite($fh, $u); ?>
In this case if pt.txt is not exist then fopen function create then after fwrite function write the string on it, if file is exist then owerwriter the content of file.
Text inside the file pt.txt
<?php $fh = fopen("ptutorial1.txt","w") ; $u="Mr brown"; fwrite($fh, $u); $u="Mr victor"; fwrite($fh, $u); fclose($fh); $fh1 = fopen("pt.txt","r") ; $s=fread($fh1,50); print $s; fclose($fh1); ?>
As i told you w is used for write mode only so that i opened this file two times first time for write something and second time for reading the file data.
