Example #1 Using file_get_contents() to retrieve data from multiple sources

<?php
/* Read local file from /home/bar */
$localfile file_get_contents("/home/bar/foo.txt");

/* Identical to above, explicitly naming FILE scheme */
$localfile file_get_contents("file:///home/bar/foo.txt");

/* Read remote file from www.example.com using HTTP */
$httpfile  file_get_contents("http://www.example.com/foo.txt");

/* Read remote file from www.example.com using HTTPS */
$httpsfile file_get_contents("https://www.example.com/foo.txt");

/* Read remote file from ftp.example.com using FTP */
$ftpfile   file_get_contents("ftp://user:pass@ftp.example.com/foo.txt");

/* Read remote file from ftp.example.com using FTPS */
$ftpsfile  file_get_contents("ftps://user:pass@ftp.example.com/foo.txt");
?>

Example #2 Making a POST request to an https server

<?php
/* Send POST request to https://secure.example.com/form_action.php
* Include form elements named "foo" and "bar" with dummy values
*/

$sock fsockopen("ssl://secure.example.com"443$errno$errstr30);
if (!
$sock) die("$errstr ($errno)\n");

$data "foo=" urlencode("Value for Foo") . "&bar=" urlencode("Value for Bar");

fwrite($sock"POST /form_action.php HTTP/1.0\r\n");
fwrite($sock"Host: secure.example.com\r\n");
fwrite($sock"Content-type: application/x-www-form-urlencoded\r\n");
fwrite($sock"Content-length: " strlen($data) . "\r\n");
fwrite($sock"Accept: */*\r\n");
fwrite($sock"\r\n");
fwrite($sock"$data\r\n");
fwrite($sock"\r\n");

$headers "";
while (
$str trim(fgets($sock4096)))
$headers .= "$str\n";

echo 
"\n";

$body "";
while (!
feof($sock))
$body .= fgets($sock4096);

fclose($sock);
?>

Example #3 Writing data to a compressed file

<?php
/* Create a compressed file containing an arbitrarty string
* File can be read back using compress.zlib stream or just
* decompressed from the command line using 'gzip -d foo-bar.txt.gz'
*/
$fp fopen("compress.zlib://foo-bar.txt.gz""wb");
if (!
$fp) die("Unable to create file.");

fwrite($fp"This is a test.\n");

fclose($fp);
?>
