Examples

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, $errstr, 30);

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 ($str = trim(fgets($sock, 4096)))

$headers .= "$str\n";



echo "\n";



$body = "";

while (!feof($sock))

$body .= fgets($sock, 4096);



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);

?>
