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);
