What are potential pitfalls when using var_export in PHP, specifically when dealing with float values that may be converted to integers?

When using var_export in PHP, a potential pitfall arises when dealing with float values that may be converted to integers. This can lead to loss of precision and incorrect data representation. To solve this issue, you can use the JSON_NUMERIC_CHECK option in json_encode to ensure that float values are encoded as strings to maintain their precision.

// Using json_encode with JSON_NUMERIC_CHECK option to preserve float precision
$data = 3.14159;
$json_data = json_encode($data, JSON_NUMERIC_CHECK);
var_dump($json_data);
