What is the significance of using the log function in PHP for mathematical calculations?

Using the log function in PHP is significant for mathematical calculations because it allows for the computation of the natural logarithm of a number. This can be useful for various applications such as calculating exponential growth or decay, determining the time it takes for a quantity to reach a certain value, or converting between different number bases.

// Calculate the natural logarithm of a number
$number = 10;
$logValue = log($number);

echo "The natural logarithm of $number is $logValue";
