本文实例讲述了php计算税后工资的方法，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 ){
    return $salary - $insurance;
  }
  $taxable_income= ($salary - $insurance -$base );
   if ($taxable_income <=1500 ){
    $ratio = .03;
    $deduct = 0;
  }else if ($taxable_income > 1500 && $taxable_income <=4500) {
    $ratio = .1;
    $deduct = 105;
  }else if ($taxable_income > 4500 && $taxable_income <=9000) {
    $ratio = .2;
    $deduct = 555;
  } else if ($taxable_income > 9000 && $taxable_income <= 35000) {
    $ratio = .25;
    $deduct = 1005;
  } else if ($taxable_income > 35000 && $taxable_income <= 55000) {
    $ratio = .3;
    $deduct = 2755;
  }
  $tax = $taxable_income * $ratio-$deduct;
  $money = $salary -$insurance-$tax;
  return $money;
}
echo "税前\t税后\n";
for ($i=5000;$i<=50000;$i+=3000)
echo $i,"\t",after_sleep($i,.08),"\n";
