This article analyzes the differences between js functions and php functions. Share it with you for your reference. The specific analysis is as follows:

In PHP syntax, a function is a structure in syntax. It is not a variable and cannot be assigned a value;
In JS, a function is also a variable. The variable name is the function name.

The Code is as follows:

<Html>
<Head>
</Head>
<Body>
<Script type = "text/javascript">
Function t (){
Return 5;
}
Var m = t; // The function name is the variable name. Note: t () cannot be written. brackets indicate that this function is called.
Alert (m ());
</Script>
</Body>
</Html>


Therefore, the declaration function can also be as follows:

The Code is as follows:

T = function (parameter ){
Function body;
}
