PHP regex matches the class div in HTML and selects the contents of the method, classdiv_php tutorial

PHP matches the class div in HTML and selects the contents of the method, Classdiv

The example in this paper is a method that PHP matches the div in HTML with class and selects the content. Share to everyone for your reference. The specific analysis is as follows:

Let's take a look at some HTML code:

Copy the Code code as follows:


Tide Table data for reference only

Tide Time (Hrs)	00:58	05:20	13:28	21:15
High tide (CM)	161	75	288	127

Time zone:-1000 (East 10) Tidal height datum: 174CM at mean sea level

This is part of the source program, in order to be easy to understand, cut a large part, just take the contents of the DIV block

Home first Use file_get_content or curl to get the content part, I use curl.
Copy the Code code as follows: $ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_post, 1);
curl_setopt ($ch, Curlopt_header, 0);
curl_setopt ($ch, Curlopt_returntransfer, 1);
curl_setopt ($ch, Curlopt_postfields, $data);
$return = curl_exec ($ch);
Curl_close ($ch);

$regex 4= "/.*?<\/div>/ism";
if (Preg_match_all ($regex 4, $return, $matches)) {
Print_r ($matches);
}else{
echo ' 0 ';
}

This is OK, not much explanation, understand the PHP code, print to see the effect.

I hope this article is helpful to everyone's PHP programming.
