看php, 太随意了：


<?php 
 
    $a = array();
    $a[0] = 1;
    $a[1] = 2;
    
    print_r($a);
?>


<?php 
    $a[0] = 1;
    $a[1] = 2;
    
    print_r($a);
?>

再看js:


<html>
<body>
 
<script>
        var myArray = new Array(); 
        myArray[0]="1";
        myArray[1]="https://cdn.jxasp.com:9143/image/2";
        myArray[2]="3";
 
        alert(myArray[0]);
</script>
 
</body>
</html>


<html>
<body>
 
<script>
        myArray[0]="1";
        myArray[1]="https://cdn.jxasp.com:9143/image/2";
        myArray[2]="3";
 
        alert(myArray[0]);
</script>
 
</body>
</html>
