In php, select echo or dump based on the variable type.

In php, echo or dump is selected based on the variable type. in this case, the is_scalar built-in function will be used.

Is_scalar -- checks whether the variable is a scalar.

Scalar variables refer to variables that contain integer, float, string, or boolean, while array, object, and resource are not scalar variables.

The code is as follows:
Function show_var ($ var ){
If (is_scalar ($ var )){
Echo $ var;
} Else {
Var_dump ($ var );
}
}
$ Pi = 3.1416;
$ Proteins = array ("hemoglobin", "cytochrome c oxidase", "ferredoxin ");

Show_var ($ pi );
// Print 3.1416

Show_var ($ proteins)
// Print:
// Array (3 ){
// [0] =>
// String (10) "hemoglobin"
// [1] =>
// String (20) "cytochrome c oxidase"
// [2] =>
// String (10) "ferredoxin"
//}
?>
