fputs() function in PHP
Write to an open file using the fpus() function in PHP. It is an alias of fwrite(). The fputs() function returns the number of bytes written on success. It returns FALSE on failure.
The fputs() function halts at the end of the file or when it reaches the specified length whichever comes first.

fputs(file_pointer, string, length)
Parameters

string − A string to be written. Required.
length − Maximum bytes to write. Optional.

$file_pointer = fopen("new.txt","w");
echo fputs($file,"This is demo text!");
fclose($file_pointer);
?>The following is the output. It returns the number of bytes written.

Let us see another example which writes a specified number of bytes to the file. The content is also read and displayed.
Example
<?php
$file_pointer = fopen("new.txt","w");
echo fputs($file,"This is demo text!",4);
fclose($file_pointer);
fopen("new.txt", "r");
echo fread($file_pointer, filesize("new.txt"));
