如何根據屏幕分辨率或大小執行php文件

[英]how to execute php file according to screen resolution or size

我有2個php文件。

include_once('medium.php');
include_once('mobile.php');

我想在屏幕尺寸> 992px時執行medium.php文件,而在屏幕尺寸<992px時執行mobile.php文件

到目前為止,我嘗試過的是:

<script>
var width = $(window).width();
if (width > 992){
</script>   
include_once('medium.php');
<script>} else{</script>
include_once('mobile.php');
<script>}</script>

但無法獲得結果。

使用jquery和ajax $.load()函數

var width = $(window).width();
if (width > 992){
  $( "body" ).load( "medium.php" );
} else{
$( "body" ).load( "mobile.php" );
}

您應該使用Ajax或Http.get將寬度過濾到PHP文件,並讓php處理執行

<?php
if(isset($_GET['size']) && $_GET['size'] > 992) {
    include_once('medium.php');
} else {
    include_once('mobile.php');
} ?>

使用jQuery.load()jQuery.post()jQuery.get()jQuery.ajax()

<script type="text/javascript">
var script = window.innerWidth > 992 ? "medium.php" : "mobile.php";
var postVars = {} // Use this to provide additional data to you PHP script, or ommit this parameter if you don't need it
var dataType = 'json'; // The type of data your PHP script will return, could be html, json, text. ommit this if you don't have a particular use for it.

jQuery.post(script, postVars, function(response) {
    // This is your callback function, you can do whatever you please with response here.
}, dataType)
</script>

安全聲明切勿信任最終用戶! 由於這是客戶端腳本,因此這些變量可以操作為例如config.php。

要解決此問題,您應該而不是請求多個腳本,而是請求一個腳本,為參數提供要包含的文件,然后檢查是否允許包含該文件。

<script type="text/javascript">
var script = window.innerWidth > 992 ? "medium.php" : "mobile.php";
var postVars = {file_to_include: script}
var dataType = 'json'; // The type of data your PHP script will return, could be html, json, text. ommit this if you don't have a particular use for it.

jQuery.post("include.php", postVars, function(response) {
    // This is your callback function, you can do whatever you please with response here.
}, dataType)
</script>

然后在您的PHP腳本中

<?php
    if(in_array($_POST["file_to_include"], array("medium.php", "mobile.php"))) {
        include $_POST["file_to_include"];
    }
?>
