In fact, compared to whlie, I prefer to use for. Here we practice the table form together. Take a look at the GIF dynamic rendering, and take a look at the code:
There is no new knowledge point, so there are no comments in the code. For novice friends who don’t know what to ask, let’s learn php~~

<?php

    $i = 0;
    while (true){
        echo "{$i}<br>";
        $i++;
        if ($i > 10){
            break;
        }
    }

    /** ***********************分割线************************* */
    echo "<table border=&#39;1&#39; align=&#39;center&#39; width=&#39;100&#39;>";
    echo "<caption><h3>iwanghang</h3></caption>";
    $i = 0;
    while ($i < 10){
        echo "<tr><td>{$i}</td></tr>";
        $i++;
    }
    echo "</table>";

    /** ***********************分割线************************* */
    echo "<table border=&#39;1&#39; align=&#39;center&#39; width=&#39;100&#39;>";
    echo "<caption><h3>iwanghang</h3></caption>";
    $i = 0;
    while ($i < 100){
        if ($i % 10 == 0){
            echo "<tr>";
        }
        echo "<td>{$i}</td>";
        $i++;
        if ($i % 10 == 0){
            echo "</tr>";
        }
    }
    echo "</table>";

    /** ***********************分割线************************* */
    $i = 0;
    while ($i < 10){
        echo "#";
        $i++;
    }
    echo "<br>";

    /** ***********************分割线************************* */
    echo "<table border=&#39;1&#39; align=&#39;center&#39; width=&#39;100&#39;>";
    echo "<caption><h3>whlie练习</h3></caption>";
    $i = 0;
    while ($i <10){
        $j = 0;

        if ($i%2==0){
            echo &#39;<tr bgcolor="#999999">&#39;;
        }else{
            echo &#39;<tr>&#39;;
        }

        while ($j < 10){
            echo "<td>$j</td>";
            $j++;
        }

        $i++;
    }
    echo "</table>";
