Page Hits Counter

Apply a page hits counter using PHP and HTML

Add a page hit counter to your website. The hit counter can be stored in a database or a file. A hit occurs whenever there is a request to a web server for a file.

Each file sent to a browser by a web server is an individual hit.

In this tutorial, every single page request will count as one hit.

	//Define the file storing the counter
	$page_hits_file = ("page_hits.txt");
	
	// Counter variable and read file into string
	$page_hits = file_get_contents($page_hits_file);
	//Increment the counter (page hits) by one
	$page_hits ++;
	
	//Open the file and prepare it for writing
	$file_handle = fopen($page_hits_file , "w");
	fwrite($file_handle , "$page_hits");
	
	//Close the file
	fclose($file_handle);

	//Display the hits
	echo $page_hits;
?>

Define the page_hits_file as page_hits.txt. Read the page_hits.txt file into a string using file_get_contents. Increment the counter variable by one. Prepare the page_hits.txt file for writing using fopen, and write the updated counter using fwrite. Close the file using fclose and display the updated page hits using the echo command.
