How can the accuracy of drawing functions in a PHP script be controlled, as seen in the example using str_replace and eval to adjust the precision of plotted points?

To control the accuracy of drawing functions in a PHP script, you can adjust the precision of plotted points by using functions like str_replace and eval to manipulate the coordinates. By adjusting the precision of the points, you can achieve a more accurate representation of the plotted data. 

// Example code to adjust the precision of plotted points in a PHP script
$plotData = "plot(1.234567, 2.345678);";

// Adjust precision to 2 decimal places
$plotData = str_replace(array('.',' '), array('',''), $plotData);
eval($plotData);
