Watch:
1, file_get_contents timeout control.
2, the page coding judgment.
3, the keyboard enter key to capture the response.
4, keyboard event compatible processing. Event = Event | | window.event;
5, XMLHttpRequest and jQuery two implementation scenarios.
6, the page and the source code at the same time display.
XMLHttpRequest version get_web.php
Copy Code code as follows:
<?php
Header ("content-type:text/html; Charset=utf-8 ");
if (!empty ($_post[' Input_text ')) {
Ini_set (' Default_socket_timeout ', 10);
if (! $data = file_get_contents ($_post[' Input_text ')) {
echo "Time out!";
return;
}
$charset _pos = Stripos ($data, ' CharSet ');
if ($charset _pos) {
if (Stripos ($data, ' utf-8 ', $charset _pos)) {
echo iconv (' Utf-8 ', ' utf-8 ', $data);
}else if (Stripos ($data, ' gb2312 ', $charset _pos)) {
echo iconv (' gb2312 ', ' utf-8 ', $data);
}else if (Stripos ($data, ' GBK ', $charset _pos)) {
echo iconv (' GBK ', ' utf-8 ', $data);
}
Return
