In PHP how can I read subvalue of an XML line? [duplicate] - php

Question

Sorry if this seems like an easy question, but I've started pulling hair out on this...
I have a XML file which looks like this...
<VAR VarNum="90">
<option>1</option>
</VAR>
I'm trying to get the VarNum.
So far I've been successful using the follow code to get the other information:
$xml=simplexml_load_file($file);
$option=$xml->option;
I just can't get VarNum (the attribute value I think?)
Thanks!

Answer 1

You should be able to get this using SimpleXMLElement::attributes()
Try this:
$xml=simplexml_load_file($file);
foreach($xml->Var[0]->attributes() as $a => $b) {
echo $a,'="',$b,"\"\n";
}
That will show you all the name/value attributes for the first foo element. It's an associative array, so you can do this as well:
$attr = $xml->Var[0]->attributes();
echo $attr['VarNum'];

Answer 2

What about using $xml['VarNum'] ?
Like this :
$str = <<<XML
<VAR VarNum="90">
<option>1</option>
</VAR>
XML;
$xml=simplexml_load_string($str);
$option=$xml->option;
var_dump((string)$xml['VarNum']);
(I've used simplexml_load_string because I've pasted your XML into a string, instead of creating a file ; what you are doing with simplexml_load_file is fine, in your case !)
Will get you
string '90' (length=2)
With simpleXML, you access attributes with an array syntax.
And you have to cast to a string to get the value, and not and instance of SimpleXMLElement
For instance, see example #5 of Basic usage in the manual :-)

[0] => Array
(
[#attributes] => Array
(
[uri] => https://abcd.com:1234/abc/cst/2/
[id] => 2
)
[name] => Array
(
[first] => abcd
[last] => efg
)
[company] => abc SOLUTION
[email] => abc#xyz.com
[homepage] => WWW.abcxyz.COM
[phone_numbers] => Array
(
[phone_number] => Array
(
[0] => Array
(
[main] => true
[type] => work
[list_order] => 1
[number] => [phone]
)
[1] => Array
(
[main] => false
[type] => mobile
[list_order] => 2
[number] => [phone]
)
)
)
[photo] => Array
(
[#attributes] => Array
(
[uri] => https://abcd.com:1234/abc/cst/2/cust_photo/
)
)
)
I applied the below code
$xml = simplexml_load_string($response);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
print_r($array);
but it is not use full i want all the data in single array in php
