The example in this article describes the method of php regularly matching divs with classes in html and selecting the content. Share it with everyone for your reference. The specific analysis is as follows:
Look at a piece of html code first:
The code is as follows:
Tide tableData is for reference only
Tide Time (Hrs) | 00:58 | 05:20 | 13:28 | 21:15 |
Tide height (cm) | 161 | 75 | 288 | 127 |
Time zone: -1000 (East 10th District) Tide height datum: 174CM below mean sea level

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 );
$regex4="/
if(preg_match_all($regex4, $return, $matches)){
print_r($matches);
}else{
echo '0';
}
That’s it, no explanation required. If you know PHP, read the code and print it to see the effect.
I hope this article will be helpful to everyone’s PHP programming design.
