note 103942 added to function.is-resource

I was recently trying to loop through some objects and convert them to arrays so that I could encode them to json strings. I was running into issues when an element of one of my objects was a SoapClient. As it turns out, json_encode() doesn't like any resources to be passed to it. My simple fix was to use is_resource() to determine whether or not the variable I was looking at was a resource. I quickly realized that is_resource() returns false for two out of the 3 resources that are typically in a SoapClient object. If the resource type is 'Unknown' according to var_dump() and get_resource_type(), is_resource() doesn't think that the variable is a resource! My work around for this was to use get_resource_type() instead of is_resource(), but that function throws an error if the variable you're checking isn't a resource. So how are you supposed to know when a variable is a resource if is_resource() is unreliable, and get_resource_type() gives errors if you don't pass it a resource? I ended up doing something like this: <?php function isResource ($possibleResource) { return !is_null(@get_resource_type($possibleResource)); } ?> The @ operator suppresses the errors thrown by get_resource_type() so it returns null if $possibleResource isn't a resource. I spent way too long trying to figure this stuff out, so I hope this comment helps someone out if they run into the same problem I did. ---- Server IP: 69.147.83.197 Probable Submitter: 97.76.37.84 ---- Manual Page -- http://www.php.net/manual/en/function.is-resource.php Edit -- https://master.php.net/note/edit/103942 Del: integrated -- https://master.php.net/note/delete/103942/integrated Del: useless -- https://master.php.net/note/delete/103942/useless Del: bad code -- https://master.php.net/note/delete/103942/bad+code Del: spam -- https://master.php.net/note/delete/103942/spam Del: non-english -- https://master.php.net/note/delete/103942/non-english Del: in docs -- https://master.php.net/note/delete/103942/in+docs Del: other reasons-- https://master.php.net/note/delete/103942 Reject -- https://master.php.net/note/reject/103942 Search -- https://master.php.net/manage/user-notes.php
