In PHP, four common methods are used to capture network data, and php4 is used to capture data. Four common methods for capturing network data in PHP, php4 for capturing data. in this section, the names are fsockopen, curl and file_get_contents, specifically, we will explore these three methods to input network data into PHP, four common methods for capturing network data, and php4 for capturing data.

This section is named fsockopen, curl and file_get_contents. Specifically, we will discuss these three methods to summarize network data input and output. I have talked a lot about fsockopen before. next I will start to transfer it to others. Here are some common methods for capturing network data.

1. use file_get_contents to get the content in get mode:

$url = 'http://localhost/test2.php';$html = file_get_contents($url);echo $html;

2. use fopen to open the url and get the content.

$url = 'http://localhost/test2.php';$fp = fopen($url, 'r');stream_get_meta_data($fp);$result = '';while(!feof($fp)){  $result .= fgets($fp, 1024);}echo "url body: $result";fclose($fp);

3. use the file_get_contents function to obtain the url in post mode.

$ Data = array ('foo' => 'bar', 'Baz' => 'boom ', 'site' => 'Www .jb51.net ', 'name' => 'nowa magic '); $ data = http_build_query ($ data); // $ postdata = http_build_query ($ data ); $ options = array ('http' => array ('method' => 'post', 'header' => 'Content-type: application/x-www-form-urlencoded ', 'content' => $ data // 'timeout' => 60*60 // timeout (unit: s ))); $ url = "http: // localhost/test2.php"; $ context = stream_context_create ($ options); $ result = file_get_contents ($ url, false, $ context); echo $ result;

4. before using the curl library, you may need to check whether php. ini has enabled the curl extension.

$url = 'http://localhost/test2.php?site=jb51.net';$ch = curl_init();$timeout = 5;curl_setopt ($ch, CURLOPT_URL, $url);curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$file_contents = curl_exec($ch);curl_close($ch);echo $file_contents;

In this section, curl and file_get_contents are named fsockopen. Specifically, these three methods are used to input network data...
