本文实例讲述了PHP计算税后工资的方法。分享给大家供大家参考。具体如下：
税前 税后 5000 3985 8000 6215 11000 8295 14000 10215 17000 12080 20000 13880 23000 15680 26000 17480 29000 19280 32000 21080 35000 22880 38000 24680 41000 26480 44000 28280 47000 30080 50000 31805

PHP
function after_sleep($salary,$housefund_ratio=0.1,$person_insurance_ratio=.08,$medical_insurance_ratio=.04)
{
$base = 3500;
$housefund = $salary * $housefund_ratio; //.10 .8
$person_insurance = $salary * $person_insurance_ratio;
$medical_insurance = $salary * $medical_insurance_ratio;
$insurance=($housefund + $person_insurance +$medical_insurance);
if ($salary - $insurance < $base ){

}
