number_format returns a string; you could instead round to two decimal places:
round($num, 2)

number_format() in PHP always returning string instead of float
This might be dumb question, but i need the answer fast, so asking here in the forum.
$num = "39.34343"
echo $num = number_format((float)$num,2, '.', '');
//output $num = "39.34"
When I echo $num always getting string in this case.
So i tried to type cast it with float
echo $num = (float)number_format((float)$num,2, '.', '')
//output $num = 39.54545454545
I need my value to be 2 decimal float
Level 1
Yes i tried with round but its not rounding up my value for some reason. Its giving same result
output $num = 39.54545454545
Level 104
That's what rounding does. So you want to subtract everything after the second decimal?
floor($num * 100) / 100

I just want my string value to be converted into 2 decimal float value. The answer you gave does work in normal case when i run in some online php compiler.
But in my case i am return that value as json response, so in the api response i am getting value as
39.5454545454554545455234234545455454545
$response['job'][$key]['cost'] = floor($cost * 100)/100;
return response()->json($response, $status_code);

JSON? Use a string representation.

string representation ? what do you mean
Level 104
$response['job'][$key]['cost'] = number_format($num, 2); // "39.54"
Level 1
Yes, this is excatly what i am doing right now, but the thing is that it gives me string as output $cost = "34.34" when i return it as json response. I want output to float number $cost = 34.34.
I guess i got no option other than converting it into float on my frontend.

@princeparaste Why are you confused? That’s what the number_format function returns: https://www.php.net/manual/en/function.number-format.php
Level 1
I just need a way to get the 2 decimal float value. I tried with round too but it didn't work.
Is there any other method to get it
Level 75
Do float first then number_format.
Just example:
$amt = (float) $array[$i][3];
$namt = number_format($amt, 2, '.', '');

Yes, i tried that but after returning as json response its getting converted into string.
$namt = number_format((float)$amt, 2, '.', '');

@princeparaste Because you’re using number_format. Which returns a string. Like the PHP docs I linked you to an hour ago says it does.
Level 75
Json is string data. Format as needed for display.
Edit:
@princeparaste do you need the number in json without parenthesis? Sorry I mean quotes.
$num = "39.34343";
$fnum = (float) $num;
$znum = round($fnum, 2);
$namt = [];
$namt["mynumber"] = $znum;
$json = json_encode($namt);
dd($json);
Output
"{"mynumber":39.34}"
or just json
{
"mynumber": 39.34
}
Use round like @t... said.
Example here, shorten as necessary. Make an accessor, whatever you need to do to store it.

@jlrdw quotes " " , not parenthesis ( )
Level 122
$num = 39.54545454;
var_dump($num) //float(39.54545454)
json_encode(['cost' => floor($num*100)/100]); // {"cost":39.54}
Level 61
@princeparaste have you tried?
$num = "39.34343"
echo $num = (float)number_format((float)$num,2, '.', '');
//output $num = 39.34
