Question

Let\'s suppose I have a string that contains \"7.2769482308e+01\" (this number came from 3rd party software, I cannot control the format).

What is t

Answer 1

Here is a very cheap one: $float = "7.2769482308e+01" + 0;

Answer 2

What about a simple cast to a float value ?

$string = "7.2769482308e+01";
$float  = (float) $string;

Answer 3

I had success using number_format(1.2378147769392E+14, 0, '', '') which was originally provided by this question.

This also works when the value is a string, like so: number_format("1.2378147769392E+14", 0, '', ''). Go ahead, give it a try.
