我想通過一個php數組到ajax函數，因爲我需要ajax函數來填充一些動態創建的表。所以爲了做到這一點，我想我必須傳遞我想要傳遞給數組的值，並且一次傳遞它們，這樣我的ajax函數就可以聲明一次，以避免上次動態表的問題只在最後填充（儘管我不太確定這是爲什麼）。還有如何$ _GET我將發送的數組參數，但到目前爲止結果是相反的，因爲它是第一個填充的動態表。所以這讓我相信只有第一個數組值被我的ajax發送。我的繼承人代碼：傳遞php數組作爲ajax函數的鏈接參數
<script>
function cat_product(val1){
if(window.XMLHttpRequest){
xhttp = new XMLHttpRequest();
}else{
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.onreadystatechange = function(){
if(xhttp.readyState == 4 && xhttp.status == 200){
window.alert(val1.length);//this proves to me that the ajax works
document.getElementById("cat_products").innerHTML = xhttp.responseText;
}
};
xhttp.open("POST","ajax/cat_product.php?id="+val1,true);
xhttp.send();
}

我試過（<?php echo '["' . implode('", "', $_SESSION['value']) . '"]'>;`？），但它像它的不可靠。
那麼AJAX網頁，我處理我的AJAX cat_product.php
$value = $_GET['id'];//$value = explode(",", $_GET["id"]);
foreach($_SESSION['value'] as $sessionValue){
if($sessionValue == $value){
//create an array of $_SESSION['sesssion_productCategory'] category keys
$ary = array_keys($_SESSION['sesssion_productCategory']);
foreach($ary as $cat_key){
//Count the created array inorder not to exceed number of products
for($j=0;$j<count($ary);$j++){
//query for displaying products
if($sessionValue == $cat_key){
$value2 = $sessionValue;
foreach($_SESSION['sesssion_productCategory'][$value2] as $key){
?>
<tr>
</tr>
<?php
}
}
}
}
}
}
?>
你可以將你的php數組作爲json的
