[英]Actually run a function a certain percentage of the time in PHP
如何在PHP中編寫函數以X%
的時間調用給定函數(匿名)?
例如:
function call_weighted(0.1, function() {
echo 'this is actually run approximately 10% of the times it is called';
});
function call_weighted($weight, $function) {
if (mt_rand() < $weight * mt_getrandmax()) {
$function();
}
}
