PHP uses AJAX to obtain web pages and output implementation code (Zjmainstay)_PHP tutorial

Highlights:
1. file_get_contents timeout control.
2. Page encoding judgment.
3. Enter key on the keyboard to capture the response.
4. Keyboard event compatible processing. //event = event || window.event;
5. XMLHttpRequest and jQuery two implementation solutions.
6. The page and source code are displayed at the same time.
XMLHttpRequest version get_web.php

Copy code The code is as follows:

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;
}
echo $data;
}else {
?>

jQuery 版本 get_web.php

复制代码 代码如下:

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;
}
echo $data;
}else {
?>
