Question

I have this array:

$methodsOutput = array("MidUpperArmMuscleArea","ArmSpan_HeightEstimation","BMIBeforePregnancy",
                "PregnancyTotalWeightGain","PregnancyWeeklyWeightGain","MS_CurrentBMI_BMIPregnancyWeeks",
                "PregnancyDueDate","PregnancyWeeks","WeightEstimation","WHO_BMI_2000_IdealBMI",
                "WHO_BMI_2000_IdealWeight","WHO_HeightAge_2006_IdealHeight","WHO_WeightAge_2006_IdealWeight");

and for each one I have the respective class (all included in file).

How can I instantiate dynamically this.

I try this:

foreach($methodsOutput as $method) {
    $$method= new $method();
}

but get:

Fatal error: Class ‘MidUpperArmMuscleArea’ not found in…

Answer 1

Do you have that class “MidUpperArmMuscleArea” ?
You could to use class_exists to test.
