The fwrite Function.
First and foremost is the fwrite function, which allows you to write string contents to the file stream referenced by the file handle. Let’s go through the following example to understand how it works.
Solutie
<?php$file_handle = fopen('C:\Users\flcri\Desktop\Solutii\3\test.txt', 'a+');fwrite($file_handle, 'Test');fwrite($file_handle, "\n");fwrite($file_handle, 'test2');fclose($file_handle);?>First, we’ve opened the C:\Users\flcri\Desktop\Solutii\3\test.txt file with the a+ mode, which opens it for reading and writing, with the file pointer placed at the end of the file. Thus, our content will be appended to the end of the file, after any other contents. Next, we’ve used the fwrite function to write a string.
The first argument of the fwrite function is the file system pointer returned by fopen—this is how fwrite knows where to write into. And the second argument is a string which we want to write into a file. As you can see in the above example, you can use the fwrite function multiple times to write a series of strings before you close the file.
Finally, we’ve used the fclose function to close the file. It takes only one argument, the file pointer that you want to close. It’s always a good practice to close files by using the fclose function once you’ve finished with your file operations.
