PHP fwrite() function is used for writing contents to a file. It write to the file stream pointed to by handle which is created by fopen() function.
Syntax of the PHP fwrite function :
fwrite( file handler, string to write , length )
Length argument is optional , and if we specify a length parameter write will stop when it write will reach to that length bytes.
PHP write() statement is binary-safe , means both binary and character data can be written to a file.
Here is a sample PHP program for writing to a file using fwrite() function
<?php $file = fopen("syam.txt","w"); fwrite($file,"Here You can learn about how to write to a file"); fclose($file); ?>
This program will create syam.txt if not exist using fopen statement and write the string “Here You can learn about how to write to a file” into that file using the handler $file and fwrite() statement.
Its only a basic tutorial about writing to files. We will discuss more about this in our later posts.
