Saving microseconds on a lot of “simple” operations in an entire PHP execution chain usually results in being able to serve more pages per second at the same speed or lowering your CPU usage. Using = NULL instead of is_null() is helpful in some cases, like loaded server scenarios where you have hundreds or thousands of requests arriving per second. However, it started happening a few times daily in the last 4 days. PHP 5.5.9 is_null – float(2.2381200790405) = – float(1.0024659633636) = faster by ~100ns per call PHP Warning: foreach () argument must be of type arrayobject, null given Resolved dukearmi (dukearmi) 4 months, 3 weeks ago Hi, I’ve been seeing the following error in my error log for months now, but it wasn’t a daily occurence. The difference is that the nullsafe operator uses a form of 'short circuiting': writing -> will cause PHP to look at whats on the lefthand side of this operator, if it's null then the righthand side will simply be discarded. The difference and overlap between the nullsafe operator and null coalescing operator feels a bit confusing at first, but I'm sure we'll get used to it. Sometimes you could use either the null coalescing or nullsafe operator, and other times you'd need to use a specific one. Not quite sure what could cause the ignorableclasses option to be NULL, it should always be set to an array (potentially an empty one) as far as I can see.However, no harm in a tiny check, to be on the safe side. Given its dynamic nature, it feels good to have a smooth way of dealing with null. ![]() In PHP 7 (phpng), is_null is drastically faster than =, although the performance difference between the two is far smaller. The nullsafe operator is definitely a missing piece of the puzzle finally added in PHP. (Yet another reason to structure your code to avoid nulls, period. So, the Non Strict Comparison ‘=’ returns bool(true). PHP will dutifully whine at you if you try to use a null value, sometimes fatally. Use is_null() or ‘=’ if there is possible of getting empty array. The loop wont be executed if terms is false / null /an empty array. Instead, it will only return a NULL value.Īn empty array is converted to null by non-strict equal ‘=’ comparison. Casting to NULLĬasting a variable to be null using (unset) $var will not remove the variable or unset its value. You can use the null or NULL, and it is case insensitive so that the output will be the same. ![]() The variable is a required argument that specifies a variable to be checked. There is only one value of type NULL, and it is the case-insensitive constant NULL. ![]()
