PHP floatval: Convert to Float Easily

The floatval function is used to convert variables to floating point numbers (decimal numbers). It attempts to convert the input into a floating point number, and if it is unable to do so, it returns 0. This function is typically used to handle user input data and ensure that the input is in numeric format.

For example:

$var = "10.5";
$floatVal = floatval($var);
echo $floatVal; // 输出 10.5
