How to use Remote Files in PHP?

[sivaranjan]

Hi friends,
I have recently started working with the PHP programming language, so I am not having much knowledge about it. I have done the basic things that are required for the basic PHP coding. Now I want to use the remote files, which I am not having any idea about doing it.!! Please tell me how to use Remote Files in PHP? Hope that someone would reply me soon.!!

As long as the media handlers URL ( "URL fopen wrappers") is enabled in php.ini with the allow_url_fopen option, you can use URLs like HTTP and FTP with the majority of functions that use a name file as a parameter. This includes include (), include_once (), require () and require_once (). Since PHP 5.2.0, allow_url_include must be enabled for these. The language of instruction include () statement includes and evaluates the specified file. The files are included following the file path provided, if none is provided, the include_path will be verified.

I would like to tell you that in PHP 4.0.3 and newer, to use the URL handlers, you must configure PHP with - enable-url-fopen-wrapper. Also you will have to keep in mind that versions of PHP for Windows earlier than 4.3 did not support remote file accessing for the following functions: include (), include_once (), require (), require_once (), and functions to create images extension functions and GD images. he language of instruction include () will issue a warning if it does not find a file while the language of instruction require () will issue a fatal error in the same case.

You can follow the following example to open a file on a remote web server, analyzing the results to extract the information you need, and then use it in an application database, or simply edit the information in the style of your site. The following example provided by me is for getting the title of a remote page :

<?php
$file = fopen ("http://www.demo.com/", "r");
if (!$file) {
    echo "<p>Unable to open remote file.\n";
    exit;
}
while (!feof ($file)) {
    $line = fgets ($file, 1024);
    if (preg_match ("@\<title\>(.*)\</title\>@i", $line, $out)) {
        $title = $out[1];
        break;
    }
}
fclose($file);
?>

If a path is defined whether full path or relative, the include_path will be ignored. When a file is included, the code it contains inherits the variable scope of the line where the include occurs. All variables available at that line in the calling file will be available in the called file, from this point. However, all functions and classes defined in the included file have global scope. Whereas the include_once () statement includes and evaluates the specified file during script execution. The behavior is similar to include (), but the difference is that if the code has already been included, it will not be a second time.

To connect with another anonymous user, you must specify a user-name (and possibly password) within the URL as ftp://user:password @ ftp.demo.com / path / to / file. You can use the same type of syntax to access files via HTTP when they require authentication. The following is an example for storing data on a remote server :

<?php
$file = fopen ("ftp://ftp.demo.com/incoming/outputfile", "w");
if (!$file) {
    echo "<p>Unable to open remote file for writing.\n";
    exit;
}
/* Write the data here. */
fwrite ($file, $_SERVER['HTTP_USER_AGENT'] . "\n");
fclose ($file);
?>
