串聯陣列以JSON編碼使用

Question

我有一個數組$選項：

[{"value":"87","text":"Accessorize","image":"accessorize.ico"},{"value":"35","text":"Adams Kids","image":"AdamsKids.ico"}] 

，但我要的是添加一個條目：

$options = ('value' => '87', 'text' => 'Accessorize', 'image' =>'accessorize.ico'),('value' => '35', 'text' => 'Adams Kids', 'image' =>'AdamsKids.ico'); 

使用json_encode產生一個輸出字符串如在此之後在開始的時候有：

[{"value":"0","text":"- Select Shop -","image":""},{"value":"87","text":"Accessorize","image":"accessorize.ico"},{"value":"35","text":"Adams Kids","image":"AdamsKids.ico"}] 

我創建了以下陣列：

$first = array('value' => '0', 'text' => '- Select Shop -', 'image' =>''); 

和我用下面cancatenation方法：

$options2 = array_merge($first, $options); 
$options2 = $first + $options; 

但兩者產生以下：

{"value":"0","text":"- Select Shop -","image":"","0":{"value":"87","text":"Accessorize","image":"accessorize.ico"},"1":{"value":"35","text":"Adams Kids","image":"AdamsKids.ico"},"2":{"value":"92","text":"Alex and Alexa","image":"alexandalexa.ico"}} 

含有這些增量的數值（實際數組包含約200個項目）。

如何添加的第一行，以獲得所需uotput，即：

[{"value":"0","text":"- Select Shop -","image":""},{"value":"87","text":"Accessorize","image":"accessorize.ico"},{"value":"35","text":"Adams Kids","image":"AdamsKids.ico"}] 

Answer 1

$options2 = array_unshift($options,$first); 

array_unshift()
