嘿，所以我試圖從我的 PHP 文件中傳遞值，我將數(shù)據(jù)從數(shù)據(jù)庫中拉到另一個(gè) PHP 文件到一個(gè)標(biāo)簽，我試圖在我進(jìn)行查詢的同一個(gè)文件上顯示我的圖像，它確實(shí)有效，但我需要它在另一個(gè)文件中。謝謝 if($image!="") { $res = mysqli_query($link,"SELECT * FROM lug_num WHERE lug_id= $image"); $array = array(); ?><br><br><div id = img_lug><?php while($row=mysqli_fetch_array($res)) { global $img; $img = $row["image"]; //echo $img; ?><img src="<?php echo $img; ?>" width='200' height='200' /><?php } ?></div><?php這是我獲取并可以顯示圖像的文件，我需要另一個(gè)文件中的 $img 變量更新所以我嘗試了會(huì)話它沒有工作說我有太多的會(huì)話我嘗試了功能相同的交易不想工作有什么方法可以用腳本完成嗎？謝謝

你嘗試的方式是錯(cuò)誤的?？矗愕?$image 變量可以是全局的，但你的循環(huán)不是全局的。它會(huì)給你循環(huán)的最后一個(gè)值。
1.將 $img 變量更改為本地變量。
2.然后創(chuàng)建一個(gè)新的全局變量。并給它這樣的值。
global $global_images;
$global_images.= "@".$row["image"]; // @ is just a separator.
3.現(xiàn)在在另一個(gè)頁面（你想要的地方），你必須再次創(chuàng)建基本循環(huán)，像這樣
include "2.php";
$get_images=explode('@', $global_image); //We can choose one by one the images with @ and explode function
//The loop
foreach ($get_images as $show){?>
<img src="<?php echo $show; ?>" width='200' height='200'>
<?php } ?>
據(jù)我了解，這正是您想要的?，F(xiàn)在您可以根據(jù)需要對其進(jìn)行自定義。
