How to write into a file in PHP?

Question

You can use a higher-level function like:

file_put_contents($filename, $content);

which is identical to calling fopen(), fwrite(), and fclose() successively to write data to a file.

Docs: file_put_contents

Consider fwrite():

<?php
$fp = fopen('lidn.txt', 'w');
fwrite($fp, 'Cats chase mice');
fclose($fp);
?>

$fp = fopen('lidn.txt', 'w');
fwrite($fp, 'Cats chase');
fwrite($fp, 'mice');
fclose($fp);

http://php.net/manual/en/function.fwrite.php

$text = "Cats chase mice";
$filename = "somefile.txt";
$fh = fopen($filename, "a");
fwrite($fh, $text);
fclose($fh);

You use fwrite()

It is easy to write file :

$fp = fopen('lidn.txt', 'w');
fwrite($fp, 'Cats chase mice');
fclose($fp);

Here are the steps:

1. Open the file
2. Write to the file

3. Close the file

   $select = "data what we trying to store in a file";
   $file = fopen("/var/www/htdocs/folder/test.txt", "w");        
   fwrite($file, $select->__toString());
   fclose($file);
   

In order to write to a file in PHP you need to go through the following steps:
