![]() ![]() ![]() This was just a basic example from me to help you understand how file handling in php works,in actual practice a database would be used for a commenting system and information such as Author,Time etc also needs to be displayed. In this tutorial we will be learning about file handling in php, as we go about this tutorial I’ll be creating a simple application that will write to a file and display the data from the file. #Fminer handle php codeIn the code above I have have striped off all the styling just to avoid any confusion and of-course our main goal is to provide what matters. Then lastly we use the for each loop to print each comment in the file, to the screen. Now since we want to read the file and print contents on a line by line basis we use the file() function (instead of fopen() in read mode) and pass the filename to it. įwrite expects 2 parameters, the file handle and the content to be written.įwrite($handle, $comment.”\n”) (\n is used for a line break). Then we write to the file using the fwrite function. Since we want to append to the same file we open the file using the fopen function in append mode (‘a’). ' /*Print the contents of the file onto the screen*/Īlthough I’ve added inline comments into the code, but we will go through the process step by step.įirst the user enters any random comment, and submits it, we then on the php script check if the variable is set and if it is not empty. $content = file('comments.txt') /*Read the file on a line by line basis*/ $handle = fopen('comments.txt','a') /*Create a handle for the file and open it in append mode since we want to add to the existing data*/įwrite($handle, $comment."\n") /*Writes users comment to the file*/ ' /*Provide a link to view the file in the browser*/ Birdeyes all-in-one platform provides remarkably easy, scalable tools to effortlessly manage online reputation, connect with prospects through digital channels. You can view the demo here – File handling with php demo index.php where all the code goes, comments.txt the file on which we will be writing data ![]() These are the files I have in the folder. R-read to a file eg :- fopen(‘filename’,’r’) Ī-append to a file eg :- fopen(‘filename’,’a’) W-write to a file eg :- fopen(‘filename’,’w’) – Note ‘w’ mode rewrites the entire file. To perform any operation on a file we need to first create a handle, to do so we need the fopen() function of php.įopen() takes in two parameters, the name of the file for which the handle is begin created and the mode in which the file should be opened.
