Question

我知道一点点php。任何人都可以告诉我如何编写一个简单的PHP脚本，以便标题中的图像每5秒左右更改一次。我不想在该图像上放置任何类型的链接只是想要更改图像。谢谢：））

Answer 1

我不太了解关于PHP的大量内容我担心但是这是一个很好的小脚本，我发现用javascript写的可能对你有帮助：

希望有所帮助。

<html>
  <head>
  <title>Image Rotate
  </head>

  <body>
  <img src="" name="Rotating" id="Rotating1" width=100 height=100>
  <img src="" name="Rotating" id="Rotating2" width=100 height=100>


  <script language="JavaScript">
  var ImageArr1 = new Array("Picture(3).jpg","Picture(1).jpg","Picture(2).jpg");
  var ImageHolder1 = document.getElementById('Rotating1');

  var ImageArr2 = new Array("Picture(5).jpg","Picture(6).jpg","Picture(7).jpg");
  var ImageHolder2 = document.getElementById('Rotating2');

  function RotateImages(whichHolder,Start)
  {
    var a = eval("ImageArr"+whichHolder);
    var b = eval("ImageHolder"+whichHolder);
    if(Start>=a.length)
        Start=0;
    b.src = a[Start];
    window.setTimeout("RotateImages("+whichHolder+","+(Start+1)+")",1500);
  }

  RotateImages(1,0);
  RotateImages(2,0);

  </script>

  </body>

PHP只能提供图像，你需要一些JavaScript来触发获取新图像的事件。

这是一种方法，改编自http://javascript.internet.com/miscellaneous/random-image-rotator.html：

<HTML>
<HEAD>

<!-- STEP ONE: The core of it: JavaScript... -->

<SCRIPT LANGUAGE="JavaScript">
<!-- Original:  Robert Bui (astrogate@hotmail.com) -->
<!-- Web Site:  http://astrogate.virtualave.net -->

<!-- Begin
var interval = 2.5; // delay between rotating images (in seconds)
var random_display = 1; // 0 = no, 1 = yes
interval *= 1000;

var image_index = 0;
image_list = new Array();
image_list[image_index++] = new imageItem("http://www.something.com/image01.jpg");
image_list[image_index++] = new imageItem("http://www.something.com/image02.jpg");
image_list[image_index++] = new imageItem("http://www.something.com/image03.jpg");
image_list[image_index++] = new imageItem("http://www.something.com/image04.jpg");
var number_of_image = image_list.length;
function imageItem(image_location) {
    this.image_item = new Image();
    this.image_item.src = image_location;
}
function get_ImageItemLocation(imageObj) {
    return(imageObj.image_item.src)
}
function generate(x, y) {
    var range = y - x + 1;
    return Math.floor(Math.random() * range) + x;
}
function getNextImage() {
    if (random_display) {
        image_index = generate(0, number_of_image-1);
    } else {
        image_index = (image_index+1) % number_of_image;
    }
    var new_image = get_ImageItemLocation(image_list[image_index]);
    return(new_image);
}
function rotateImage(place) {
    var new_image = getNextImage();
    document[place].src = new_image;
    var recur_call = "rotateImage('"+place+"')";
    setTimeout(recur_call, interval);
}
//  End -->
</script>
</HEAD>

<!-- STEP TWO: Insert the onLoad event handler into your BODY tag  -->

<BODY OnLoad="rotateImage('rImage')">

<!-- STEP THREE: Copy this code into the BODY of your HTML document  -->

<center>
<img name="rImage" src="http://www.something.com/image01.jpg" width=120 height=90>
</center>

</BODY>
</HTML>

我需要一个脚本来使标题图像每10秒左右更改一次？
