Php exponentially

When I output some of my double variables, they are written exponentially using fwrite. Can I set some default values ​​in PHP, where whenever a variable is displayed (copied or saved), it always happens in decimal format?

To be precise, the problem occurs when I use the json_decode method on a json string that contains a double value (which is not in exponential form). This double value after the transformation of the object becomes exponential.
