how do you read or write file from the PHP code example

Example 1: read file using php

/*
In php to read file first you have to use 'fopen' method to open the file after that you perform different operation on it.
Like Reading file, Writing file etc.
  
TO read file data we have to use 'fread' method.
*/

<?php
$myfile = fopen("read_text_file.txt", "r") or die("Unable to open file!");
echo fread($myfile,filesize("read_text_file.txt"));
fclose($myfile);
?>
  
/*
I hope it will help you.
Namaste

Example 2: php write to file

$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "Bobby Bopper\n";
fwrite($fh, $stringData);
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);
