What are common challenges faced when converting microseconds to seconds in PHP?

When converting microseconds to seconds in PHP, a common challenge is ensuring the correct precision and accuracy in the conversion. One way to solve this is by dividing the microseconds by 1,000,000 to get the equivalent value in seconds. It is important to handle any potential rounding errors that may occur during the conversion process.

// Convert microseconds to seconds with precision
$microseconds = 123456789; // example value
$seconds = round($microseconds / 1000000, 6); // divide by 1,000,000 to get seconds with 6 decimal places precision
echo $seconds;
