I am taking the request from the user and store it in $request variable based on this i am fetching some key value up to this it's working fine ,after this i am passing this value to the switch case statement what it does means if the value is double/float type it will do some operations inside that case , similarly for string and integer also .but even if i pass integer or double/float type it will go the string case only .can you please help me where did i mistake..
my api {url}/details?limit=25&amount=99.9 sometimes amount is 99 or NinteyNine
Public function run(){
$request=new Request();
$value=$request->amount;
switch(gettype($value)){
case 'double':
//perform some logic if type is double
break;
case 'string':
//perform some logic if type is string
break;
default:
//perform some logic if type is Integer
}
}
what ever the value is passed it's considered as a string type only i need to fix this issue please help me..
I think $request->amount will always return a string since the URL query parameters are also strings.
is_numeric() finds whether a variable is a number or a numeric string. In your case, it is returning true because it is a numeric string.
You could do:
function amountType(string $amount): string {
if (is_numeric($amount)) {
if ((int) $amount == (float) $amount) {
return "int";
}
return "float";
}
return "string";
}
$type = amountType($request->amount);
switch($type) {
case 'float':
//perform some logic if type is double
break;
case 'string':
//perform some logic if type is string
break;
case 'int':
//perform some logic if type is Integer
break;
default:
// Invalid type
}

Alternatively, if the behaviour of float and int inputs are the same, you could also do:
$amount = $request->amount;
if (is_numeric($amount)) {
$numericAmount = (float) $amount;
// Perform some logic if input is numeric
return;
}
// Perform some logic if input is string
return;
