Checking what methods and properties these classes have to offer is a good place to start. Our example here will not use so many technical artifacts, but will be based on similar logic just to get the point across.
On production systems, warnings are usually shut off, but they are often active on development systems. You might want to examine the return value of those functions in detail, but since both are specified to return boolean types there should be no doubt. For example, I have a soap server I am querying using a soap client and if I call a get method, I am either returned an object containing fields defining the soap query I have made otherwise I am returned object stdClass 3 0 . One of the user contributed code on the php empty page which I think addresses your problem of checking if the array is filled but has empty values.
Go optimize something that matters. The overall result was a 200% speed increase when the array was indeed empty, but an average 10% slow when it had elements inside. This parameter is false by default. Beware recursive functions shouldn't go over 100 deep or could break the memory stack on server. Otherwise it can be assumed to be an associative array something unobtainable in languages such as C. In the end on a ratio of 3 not empty arrays to 1 empty array computed for 1000000 iterations it needed 10% less time. I'll try logging a bug in the Answers hub. As far as this thread goes.
PHP object isset and/or empty - I'm summarising a few points on empty with inaccessible properties, in the hope of saving others a bit of time.
No warning is generated if the variable does not exist. That means empty is essentially the concise equivalent to. Although it's noted in the documentation above, I think it's worth mentioning in more detail as the behaviour is not straightforward. In order to achieve desired expexted. I'm summarising a few points on empty with inaccessible properties, in the hope of saving others a bit of time. Your code will just go wrong silently, and I would say it amounts to a bug. So things are not as clear as we might hope. See also the note on empty at Clear as mud. I'm just using something for the sake of examples. Note that checking the existence of a subkey of an array when that subkey does not exist but the parent does and is a string will return false for php check if object is empty. Non-integer types are converted to integer. I did a quick benchmark over the most common ways of testing it. I would encourage the use of trim which would most likely be faster haven't tested and easier. Trim also takes care of other white space like line breaks and tabs. The good thing about doing this is that you never have to worry about 'trimming' your input which makes your code easier and more reliable incase you forget to trim some input. There are good alternatives e. Besides that, it automatically documents the code. This parameter is false by default. This parameter is false by default. On production systems, warnings are usually shut off, but they are often active on development systems. Instead of you can simply use for easy readability without warnings. On entries like name, profession. For who don't want to test what happen if passed an array element here is my test and result. For example: bar is '. Mad Hampster did his test wrong. But if you are dealing with intermediate or higher level coders this function has no other benefit. These are my results generated one one page request. Re: inerte is my gmail. When programming for web interfaces, where a user may be submitting '0' as a valid field value, you should not be using empty. In addiction to Ed comment: if an instance variable is assigned with an empty value, i. But somehow using empty function is faster for about 10-13% '. } otherwise the condition will not evaluate to true in case a mysqli error is given for the present connection.
