4.Numerical string conversions now respect scientific notation Integer operations and conversions on numerical strings now respect scientific notation. This also includes the (int) cast operation, and the following functions: intval() (where the base is 10), settype(), decbin(), decoct(), and d...
Behind the scenes, it basically links each function in a chain-like manner by passing the return value of one as input to the next. In this case, the string “Functional PHP Rocks!” was passed into htmlentities which returns an HTML-escaped string, passed into $repeat(2), and finally...

In the following example we try to send both a number and a string to the function, but here we have added thestrictdeclaration: Example <?phpdeclare(strict_types=1);// strict requirementfunctionaddNumbers(int$a,int$b){return$a+$b;}echoaddNumbers(5,"5 days");// since strict is enab...

Phan checks the type of every single element of arrays (Including keys and values). In practical terms, this means that[$int1=>$int2,$int3=>$int4,$int5=>$str6]is seen asarray<int,int|string>, which Phan represents asarray<int,int>|array<int,string>.[$strKey => new MyClass()...
