PHP get Web content Method Summary

Method 1: Use file_get_contents to get the content in the Get mode
<?php
$url = ' http://www.domain.com/?para=123 ';
$html = file_get_contents ($url);
Echo $html;
?>

Method 2: Use the file_get_contents function to get the URL by post
<?php
$url = ' http://www.domain.com/test.php?id=123 ';
$data = Array (' foo ' = ' bar ');
$data = Http_build_query ($data);

$opts = Array (
' http ' = = Array (
' Method ' = ' POST ',
' Header ' = ' content-type:application/x-www-form-urlencoded\r\n '.
"Content-length:". Strlen ($data). "\ r \ n",
' Content ' = $data
)
);
$ctx = Stream_context_create ($opts);
$html = @file_get_contents ($url, ", $ctx);

If you need to pass the cookie data again,
' Header ' = ' content-type:application/x-www-form-urlencoded\r\n '.
"Content-length:". Strlen ($data). "\ r \ n",
Revision changed to
' Header ' = ' content-type:application/x-www-form-urlencoded\r\n '.
"Content-length:". Strlen ($data). "\ r \ n".
"Cookie:cookie1=c1;cookie2=c2\r\n";
Can

Method 3: Open the URL with fopen and get the content in Get mode
<?php
$fp = fopen ($url, ' R ');
$header = Stream_get_meta_data ($FP);//Get header information
while (!feof ($fp)) {
$result. = Fgets ($fp, 1024);
}
echo "URL header: {$header} <br>":
echo "URL body: $result";
Fclose ($FP);
?>

Method 4: Open the URL with fopen and post to get the content
<?php
$data = Array (' foo2 ' = ' bar2 ', ' foo3 ' = ' bar3 ');
$data = Http_build_query ($data);

$opts = Array (
' http ' = = Array (
' Method ' = ' POST ',
' Header ' = ' content-type:application/x-www-form-urlencoded\r\ncookie:cook1=c3;cook2=c4\r\n '.
"Content-length:". Strlen ($data). "\ r \ n",
' Content ' = $data
)
);

$context = Stream_context_create ($opts);
$html = fopen (' http://www.test.com/zzzz.php?id=i3&id2=i4 ', ' RB ', false, $context);
$w =fread ($html, 1024);
echo $w;
?>

Method 5: Open the URL with the Fsockopen function and get the full data in Get mode, including header and body
<?php
function Get_url ($url, $cookie =false)
{
$url = Parse_url ($url);
$query = $url [path]. "?". $url [query];
echo "Query:". $query;
$fp = Fsockopen ($url [host], $url [port]? $url [port]:80, $errno, $errstr, 30);
if (! $fp) {
return false;
} else {
$request = "GET $query http/1.1\r\n";
$request. = "Host: $url [host]\r\n";
$request. = "connection:close\r\n";
if ($cookie) $request. = "Cookie: $cookie \ n";
$request. = "\ r \ n";
Fwrite ($fp, $request);
while ([email protected] ($FP)) {
$result. = @fgets ($fp, 1024);
}
Fclose ($FP);
return $result;
}
}
Gets the HTML part of the URL, removing the header
function geturlhtml ($url, $cookie =false)
{
$rowdata = Get_url ($url, $cookie);
if ($rowdata)
{
$body = Stristr ($rowdata, "\r\n\r\n");
$body =substr ($body, 4,strlen ($body));
return $body;
}

return false;
}
?>

Method 6: Use the Fsockopen function to open the URL, post to get the full data, including header and body
<?php
function Http_post ($URL, $data, $cookie, $referrer = "")
{

Parsing the given URL
$URL _info=parse_url ($URL);

Building referrer
if ($referrer = = "")//if not given with this script as referrer
$referrer = "111";

Making string from $data
foreach ($data as $key = $value)
$values []= "$key =". UrlEncode ($value);
$data _string=implode ("&", $values);

Find out which port was needed-if not given use standard (=80)
if (!isset ($URL _info["Port"))
$URL _info["Port"]=80;

Building Post-request:
$request. = "POST". $URL _info["path"]. " Http/1.1\n ";
$request. = "Host:". $URL _info["host"]. " \ n ";
$request. = "Referer: $referer \ n";
$request. = "content-type:application/x-www-form-urlencoded\n";
$request. = "Content-length:". strlen ($data _string). " \ n ";
$request. = "connection:close\n";

$request. = "Cookie: $cookie \ n";

$request. = "\ n";
$request. = $data _string. " \ n ";

$fp = Fsockopen ($URL _info["host"], $URL _info["Port"]);
Fputs ($fp, $request);
while (!feof ($fp)) {
$result. = Fgets ($fp, 1024);
}
Fclose ($FP);

return $result;
}

?>

Method 7: Using the Curl Library, before using the Curl Library, you may need to see if php.ini has the curl extension turned on
<?php

$url = "Http://172.168.1.16:8080/tongi/user/mobileValidation.do";
$post _data = Array ("mobile" = ' {$mobile} ');
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_returntransfer, 1);
Post data
curl_setopt ($ch, Curlopt_post, 1);
Variables for post
curl_setopt ($ch, Curlopt_postfields, $post _data);
$output = curl_exec ($ch);
Curl_close ($ch);
Echo $output;

?>
