This is my code:
This is a copy of the remote xml I am trying to parse:
Now when I run my script it errors with:
explode() expects parameter 2 to be string, array given in D:\wamp\www\xpathtest.php on line 9
Now, I assume that the error means that my $result is an array and needs to be a string?
PHP:
<?php
//a XML you want to retrieve
$xml = simplexml_load_file('url.com');
//Find the Second <description> tag and put contents into a string
$result = ($xml->xpath("//description[1]"));
// break $result using the br character as the delimiter
$number = explode('br', $result);
//removes every character & symbol except numbers
$number = preg_replace("/\D/", "", $number);
//print the number on it's own
echo $number;This is a copy of the remote xml I am trying to parse:
