phpFile Managment

php File Managment:

 Alright i am back after a long time so ... my new topic from today file management , no doubt its play an important role for any programming language its also important for php as well.
so i am starting from basic for file management operations.

we need to open a file,read a file ,do some modifications in files, i will discuss today how to read files in php.

Example:

<?php

// read files from my destination
$file = 'destination/phpguidefile.txt' or die('file not Found');
// to open file we use fopen
$fh = fopen($file, 'r') or die('file unable to open');
// to read file data/text use fread
$content = fread($fh, filesize($file)) or die('Reading Error');
// also its important to close file use fclose
fclose($fh);
// Echo text/data from file in php script
echo $content;

?>

Read All Files From Directory

If we want to read all files name or specific files name from directory , no need of worry php provide B.I.F(built in function) name as glob().

What this method do?
glob search path name with provide patterns and fetch all related files.

glob('dirname'/*.*');
above method will fetch all files with any extensions we can also fetch particular extensions using below syntax
glob('*.ext');
