在ajax中逐個顯示foreach數組項目

Question

在PHP中，我從foreach獲取數組。我是JSON編碼並一次顯示所有結果。這工作正常。但是如果我需要逐個顯示數組項目，那麼foreach仍然會繼續？

<?php 
$array = //somearray; 
$data_arr = array(); 
foreach($array as $arr){ 
//do something 
$data_arr[] = $arr; 
} 
echo json_encode(array('success'=>true,'data'=>$data_arr)); 
//here i can display the data in my jquery using each function 
//i can display the whole data at once after the foreach is completed 
//what i need is i want to display first element of data_arr after its loop is completed and then the second element and so on

Answer 1

你嘗試http://www.php.net/array_shift？它的PHP功能，你需要調用後，該功能

<?php 
foreach($array as $arr){ 
//do something 
$data_arr[] = $arr; 
} 

print_r array_shift($data_arr); 
//Print First array value from this $data_arr list. 

?> 

謝謝。
