I am parsing the xml like following:
$result = '
<sms>
<status>0</status>
<message>
<contact_lists>
<contact_list><cl_id>11111</cl_id><phone>999999999</phone><name>Neu</name></contact_list>
<contact_list><cl_id>222222</cl_id><phone>888888888</phone><name>Alt</name></contact_list>
</contact_lists>
</message>
</sms>';
$xml = simplexml_load_string($result, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$array = json_decode($json,true);
$contact_lists = $array['contact_lists']['contact_list'];
A
sometimes the array look like this, which is works.
Array ( [status] => 0 [message] => Array ( ) [contact_lists] => Array ( [contact_list] => Array ( [0] => Array ( [cl_id] => 11111 [phone] => 999999999 [name] => Neu ) [1] => Array ( [cl_id] => 222222 [phone] => 888888888 [name] => Alt ) ) ) )
B
but sometime if the array has only one contact_list, it will look like following
Array ( [status] => 0 [message] => Array ( ) [contact_lists] => Array ( [contact_list] => Array ( [cl_id] => 11111 [phone] => 999999999 [name] => Neu ) ) )
when i use$contact_lists
in foreach loop it works withA
since there are multiple array keys like 0,1,2,etc... but withB
it shows errorWarning: Illegal string offset 'name' etc..
since there are no array key like 0,1,2,etc...
so parsing the xml is automatically removing the key numbering which causing the the issue.
1- is there a way to keep the key numbering if only one array?
2- tried to useif (count($contact_lists) >= 1) {
, but its not working as well..
Any idea for a workaround to solve such issue ?
SOLUTION:
$contact_lists_found = isset($array['contact_lists']['contact_list']) ? $array['contact_lists']['contact_list'] : '';
if ($contact_lists_found !== '' ) {
if (array_key_exists('0', $contact_lists_found)) {
// more than contact list
$contact_lists = $array['contact_lists']['contact_list'];
} else {
// only one contact list
$contact_lists[0] = $array['contact_lists']['contact_list'];
}
} else {
$contact_lists = array();
}
You could just check, if the key0
is set, and if not, then simply overwrite the elementcontact_list
with itself wrapped into an array:
if(!isset($array['message']['contact_lists']['contact_list'][0])) {
$array['message']['contact_lists']['contact_list'] = [
$array['message']['contact_lists']['contact_list']
];
}
0
is not a valid tag name in XML, so you should never get that, unless there was more than one<contact_list>
in the XML.
