Finding the length of a scalar variable with the length function

Finding the length of a scalar variable with the length function

Finding the length of a scalar variable is incredibly easy using the length function. The syntax of length is as follows:
```
length ([$variable_name]); 
```
Thus, if the scalar variable $name equals "Selena", then the scalar variable $length_of_name will be assigned the value of six in the following line:
```
$length_of_name = length ($name); 
```
