May be an array or may not

[blinks]

I've the following line -

 

$rsd_pids=$parsed_xml['PIDs']['pid'];

 

which reads the content of the <pid> tag of an XML file.

 

Sometimes there may be one <pid> tag, and sometimes more. My code works fine - creates an array - if there is more than one PID tag. $rsd_pids becomes a string if there is just one <pid>. How do I force it to read a single value as an array, not a string?

 

TIA

$rsd_pids[] = $parsed_xml['PIDs']['pid'];

$rsd_pids = (array)$parsed_xml['PIDs']['pid'];

This will enforce it into an array rather string or not.

Thanks heaps! This works beautifully!
