Tutorial for Closing File in PHP

Closing file in php is all related to fclose( ) Function. With the help of this code we can run closing function in php.

What is fclose( ) Function in php?

In PHP, the fclose() method is used to close a file referenced by an open file pointer. If the method fclose() is successful, it returns true; otherwise, it returns false. It accepts the file that needs to be closed as an input and closes it.


bool fclose( $file )


The $file argument is the only one accepted by PHP’s fclose() function. The file that has to be closed is specified by this argument.

Return Value:

If it succeeds, it returns true; if it fails, it returns false.

Errors And Exception:

  • If you want to read the contents of a file that was written using the fwrite() function, you must first shut it with the fclose() function.
  • For remote files, PHP’s fclose() method does not work. It only works with files that the server’s filesystem can access.

Let’s take examples to explain this function:

Input : $check = fopen("gfg.txt", "r");
Output : true

Input: $check = fopen("singleline.txt", "r");
       $seq = fgets($check);
       while(! feof($check))
         echo $seq ;
         $seq = fgets($check);

Example 1:-


Example 2:- The file test.txt in the software below includes just one line: “This file contains only one line.”

Tutorial for fread() in Reading file

What is fread()?

The file’s data is read using the PHP fread() function. Two parameters are required: file resource and file size.

Read the File using fread()

Using the fread() method, we may read content from an already open file. There are two parameters to the fread() function:

  • first is the filename
  • and the second argument specifies the size in bytes for the content to be read.


Let’s take an example, if we have a file studytonight.txt with following content:

Studytonight is for coding enthusiasts!

If we wish to read the file’s complete content, we’ll open it in read mode and then use the fread() method.

PHP readfile() Function

Reads a file and publishes it to the output buffer with the readfile() method.

Assume we have a text file on the server named “webdictionary.txt” that looks like this:

AJAX = Asynchronous JavaScript and XML
CSS = Cascading Style Sheets
HTML = Hyper Text Markup Language
PHP = PHP Hypertext Preprocessor
SQL = Structured Query Language
SVG = Scalable Vector Graphics
XML = EXtensible Markup Language

The following is the PHP code for reading the file and writing it to the output buffer (the readfile() method returns the number of bytes read if successful):
