In this article, we are going to discuss how to write into a text file using the PHP built-in fwrite() function.
The fwrite() function is used to write into the given file. It stops at the end of the file or when it reaches the specified length passed as a parameter, whichever comes first. The file has to close by using the PHP fclose() function.
Syntax:
fwrite(file_name, string)
- file_name: The name of the input file
- string: The content to be written.
Return Value: It returns the number of bytes written on success, or false on failure.
Example 1: The code example below shows how to write a text to the “neveropen_data.txt” file.
PHP
<?php// Open a file named neveropen_data in write mode$data = fopen("neveropen_data.txt", "w");// writing content to a file using fwrite() functionecho fwrite($data, "This data is added as extra");// closing the filefclose($data);?> |
neveropen_data.txt: When the user opens this text file, the following text content is found after opening it.
This data is added as extra
Output:
27
Example 2:
PHP
<?php// Open a file named neveropen_data in write mode$data = fopen("neveropen_data.txt", "w");// writing content to a file using fwrite() functionecho fwrite($data, "This data is added as extra along with previous data");// closing the filefclose($data);?> |
neveropen_data.txt: The following content is found after opening the file.
This data is added as extra
along with previous data
Output:
