11 – PHP File Handling: Writing to Files


In our last tutorial, we discussed on how access file using PHP. At this we’re going to focus on how write into a file. Since we know how to access files, writing into a file is really simple. To start on lesson lets create a new PHP file called “writefile.php”.  Then add the following code:


When you execute the code above, and then when you open the hello.txt file it will look like as shown below:


And if you notice that when we issue another write statement,its just pick where are left off. So introduce to us the idea of a pointer that works like a cursor.  So while the file is open, it puts it into the beginning of the file and waiting for us to type, and we do it using fwrite($fh, “hello”); and then the cursor can be found at the side of the letter “o” and then when add another  fwrite($fh, “World”); it append the second word to our first word.

 Here’s the another example.

Here in our new code you have noticed that in order for us to move the “world” into the next line we use these $greetings = “hello\r\nWorld”; because we are using windows platform. And for UNIX you can simply use $greetings = “hello\nWorld”;.


The output of the code above will now look like as shown below.
