PHP中的循环问题计数年份 [英] Loop Issue Counting Year In PHP

问题描述

我创建了一个循环，它将以格式化的方式显示日期 2004 到 2014.但问题是，它显示的是 204 而不是 2004 并一直持续到 209.那么，如何以格式化的方式显示那些年份，例如 2004、2005、2006 等
这是我创建的代码，告诉我在哪里修复:

I have created a loop which will display date 2004 to 2014 in a formatted way. But the problem is, it is showing 204 instead of 2004 and continue this till 209.. So, how to show those year in formatted way, like 2004,2005,2006 etc.
Here is the code i have created, tell me where to fix:

<?php
    $yr = 4;
    while ($yr <= 14) {
        $x = 1;
        while ($x <= 31) {
            echo "$x Jan 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Feb 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Mar 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Apr 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x May 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Jun 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Jul 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Aug 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Sep 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Oct 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Nov 20$yr<br>";
            $x++;
        }
        $x = 1;
        while ($x <= 31) {
            echo "$x Dec 20$yr<br>";
            $x++;
        }
        $yr++;
    }
?>

推荐答案

根据你的代码，你可以试试这个.虽然这不是标准方式:

According to your code, you can try this. Though its not a standard way:

<?php
$yar = 4;
while ($yar <= 9) {
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Jan 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Feb 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Mar 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Apr 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax May 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Jun 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Jul 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Aug 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Sep 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Oct 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Nov 200$yar <br>";
        $ax++;
    }
    $ax = 1;
    while ($ax <= 31) {
        echo "$ax Dec 200$yar <br>";
        $ax++;
    }
    $yar++;
}
$yr = 10;
while ($yr <= 14) {
    $x = 1;
    while ($x <= 31) {
        echo "$x Jan 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x Feb 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x Mar 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x Apr 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x May 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x Jun 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x Jul 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
        echo "$x Aug 20$yr <br>";
        $x++;
    }
    $x = 1;
    while ($x <= 31) {
