使用下一步按钮调用数组值单击php

Question

echo "Associative 2-dimensional array:<br>";

$marks1=array(
    array("Maths"=>80,"Physics"=>89,"Chemistry"=>79),
    array("Maths"=>90,"Physics"=>78,"Chemistry"=>87),
    array("Maths"=>78,"Physics"=>90,"Chemistry"=>79)
);
echo "<ul>";
for($r=0;$r<count($marks1);$r++)
{
    echo "<li>";
    foreach($marks1[$r] as $key=>$value)
    {
        echo $key." = ".$value."  ";
    }
    echo "</li>";
    echo "<br><br>";
}
echo "</ul>";

如何通过点击按钮获得点击?如果我点击按钮获得数学= 80物理= 89化学= 79，然后再次点击按钮获得数学= 90物理= 78化学= 87，请建议

您可以将内容附加到一个div并递增一个计数器，就像id post_fix一样遵循我为您创建的这个简单示例。

<?php 
echo "Associative 2-dimensional array:<br>";

$marks1=array(
    array("Maths"=>80,"Physics"=>89,"Chemistry"=>79),
    array("Maths"=>90,"Physics"=>78,"Chemistry"=>87),
    array("Maths"=>78,"Physics"=>90,"Chemistry"=>79)
);
echo "<ul>";
for($r=0;$r<count($marks1);$r++)
{
    echo "<li>";
    foreach($marks1[$r] as $key=>$value)
    {
        echo "<span id='$key$r'>".$key." = ".$value."</span>  ";
    }
    echo "</li>";
    echo "<br><br>";
}
echo "</ul>";

?>
<button onclick="show()">Show</button>
<div id="here"></div>
<script type="text/javascript">
    var i=0;
        function show()
        {

            document.getElementById("here").innerHTML = document.getElementById("Maths"+i).innerHTML;
            i++;
        }
</script>

希望这会对你有所帮助。
