In this tutorial I’m going to show how to read back information from files. So before we can read information from a file we need to use a function fopen just to open the file for reading. In this lesson, we’re going to use the “hello.txt” file that we created in the writing of file lesson.
To start in this lesson, we are going to create a new PHP file called readfile. Then add the following code:
We have this result because we simply specify the number of characters we want to display, in our case we write five(5) character. But what if we want to read the entire file and you don’t know how many byte the file is. And add the following code for the second example.
But I have here another way using the shortcut for fopen/fread/fclose, and this is also a companion to shortcut <code> file_put_contents(filename, data)</code>. And here’s add the following code.
