php SimpleXML check if a child exists

Question

A->b->c might exist but c might not exist. How do I check it?

Answer 1

Name Spaces

Be aware that if you are using name spaces in your XML file you will need to include those in your function calls when checking for children otherwise it will return ZERO every time:

if ($XMLelement->children($nameSpace,TRUE)->count()){
    //do something here 
}
