如何将“查看页面源代码”复制到新文件中？ [关闭]

When you right click here. you will find 'View Page Source' on clicking that, a new window opens with source code of that page.

My question is how would I copy those source code into new file either using javascript , jquery or using php.

Using jQuery:

$.get( "http://www.example.com/", function( data ) {
  console.log(data);
});

Using PHP:

$homepage = file_get_contents('http://www.example.com/');
print_r($homepage);

Reading from a URL and writing to a file:

file_put_contents('example_site.html', file_get_contents('http://www.example.com'));

Note: Make sure you have write permissions in the directory where you are exporting this file to.

To display HTML data without browser rendering it:

$html= "<h1>Hello</h1>";
echo htmlspecialchars($html);
