Parsing Files in PHP

Let's consider the general principle of downloading files during parsing. This is done using the function file_get_contents, which is passed a parameter of some URL pointing to the file we want to download:

<?php
	$data = file_get_contents('http://file-url');
?>

Then, using the function file_put_contents we can save the downloaded data into a file:

<?php
	file_put_contents('file-name', $data);
?>

However, there is a nuance. The function file_get_contents, depending on the settings, may open URLs, or it may not. To do this, we need to check what value the PHP setting 'allow_url_fopen' is set to. Let's do this using the function ini_get:

<?php
	$val = ini_get('allow_url_fopen', true);
	var_dump($val); // должно быть true или 1
?>

In case the setting is not enabled, we can enable it using the function ini_set:

<?php
	ini_set('allow_url_fopen', true);
?>

Check your 'allow_url_fopen' setting. If it is disabled, enable it.
