How to extract information from Dynamic Domain with PHP - php

Question

Hello I'm trying to get this information from an HTML page but it doesn't have element,class, nothing it just have <pre>all content</pre> how can I extract the value from "validTo"? Information below
It is not a JSON FILE, its just the content of the web page.
[serialNumber] => 984924526890779987
[validFrom] => 180515204024Z
[validTo] => 180807195300Z
[validFrom_time_t] => 1526416824
PHP Code:
<?php
$url = "https://www.google.es";
$orignal_parse = parse_url($url, PHP_URL_HOST);
$get = stream_context_create(array("ssl" => array("capture_peer_cert" => TRUE)));
$read = stream_socket_client("ssl://".$orignal_parse.":443", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $get);
$cert = stream_context_get_params($read);
$certinfo = openssl_x509_parse($cert['options']['ssl']['peer_certificate']);
echo $certinfo

Answer 1

Something like this will work if the page is formatted the way you described.
// get the webpage - replace your.url with the actual webpage address
$html = file('your.url',FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES) ;
// get your value
foreach($html as $line) {
$result = strpos($line,'[validTo]') ;
if (false !== $result) {
$temp = explode('=>', $line) ;
$validTo = trim($temp[1]) ;
break ;
}
}

Consider your file has this content
file.html
[serialNumber] => 984924526890779987
[validFrom] => 180515204024Z
[validTo] => 180807195300Z
[validFrom_time_t] => 1526416824
Now this will extract the info and put it into an array named $arr. Access each by using that array.
<?php
$data = file_get_contents('http://domain/file.html');
$arr = explode(PHP_EOL, $data);
echo $arr[0];
?>

Hi you can extract more info from a string by using Regex.
<?php
$string = "
<pre>
[serialNumber] => 984924526890779987
[validFrom] => 180515204024Z
[validTo] => 180807195300Z
[validFrom_time_t] => 1526416824
</pre>
";
preg_match('/\[validTo\].[\=\>].*[0-9a-zA-Z]/', $string, $values, PREG_OFFSET_CAPTURE);
print_r($values);
The Result was:
Array
(
[0] => Array
(
[0] => [validTo] => 180807195300Z
[1] => 97
)
)
