Read files from folder using php

Read files from folder using PHP

Today we learn how to read all files from a folder . we will learn to list all files and read all files . So please follow below steps:-  

METHOD 1

1) List all files from folder If you want the list of all files in a folder then you can do by using below code

 
//Get a list of file paths using the glob function.
  $allFilesList= glob('myfolder/*');
  //Loop through the array that glob returned.
  foreach($allFilesList as $filename){
    //Simply print them out onto the screen.
    echo $filename; echo  '<br>';

  }

The above code will print list of all files like

 
 file1.jpg
 file2.png
 file3.gif
 file4.pdf

If you want to read only specific extension file like you just want to a list of all png files then you can do it by using below code.

 
//Get a list of all files ending in .txt
$fileList = glob('myfolder/*.png);

METHOD 2
Here is the second method. here we are using scandir() function to scan all files in a directory.

 
$files = scandir('./');
    if(count($files) > 0) {
        foreach ($files as $key => $value) {            
            echo '<pre>'; print_r($value); echo '</pre>';
            // to read files data
            $readFileVar = fopen ($value, "r");
             while ($filedata = fgets($readFileVar)) { 
                 print_r($filedata);
              }
        }
    }

Above code will scan the directory and list all the files of that directory. and fopen will open file and fgets() function will read content from that file. So the above methods are easy methods to scan and read directory and print list and read content from it.

Thank you.
