数组声明中的 if 语句......这可能吗? [英] If statement within an array declaration ...is that possible?

问题描述

可能的重复:
数组中的条件元素(…)构造

这是我的代码

$product_option_value_data[] = array(
    'product_option_value_id' => $product_option_value['product_option_value_id'],
    if (isset($product_option_value_description_query->row['smallimage'])) {
        'smallimage'                  => $product_option_value_description_query->row['smallimage'],
    }
    'name'                    => $product_option_value_description_query->row['name'],
    'price'                   => $product_option_value['price'],
    'prefix'                  => $product_option_value['prefix']
);

我可以这样做吗....

can i do something like this....

这是我的错误

  Parse error: syntax error, unexpected T_IF, expecting ')' in /Users/mattelhotiby/Sites/posnation/shop_pos/catalog/model/catalog/product.php on line 419 

其实我是这样做的

if (isset($product_option_value_description_query->row['smallimage'])) {
    $smallimage = $product_option_value_description_query->row['smallimage'];
}else{
    $smallimage = '';
}
$product_option_value_data[] = array(
    'product_option_value_id' => $product_option_value['product_option_value_id'],
    'smallimage'                  => $smallimage,
    'name'                    => $product_option_value_description_query->row['name'],
    'price'                   => $product_option_value['price'],
    'prefix'                  => $product_option_value['prefix']
);

但我仍然想知道在这个数组声明中有一种方法可以做一个 if

But i still want to know f there is a way to do an if within this array declaration

推荐答案

不是 if，但类似的事情是可能的:

Not an if, but a similar thing is possible:

$product_option_value_data[] = array(
    'product_option_value_id' => $product_option_value['product_option_value_id'],
    'smallimage' => (isset($product_option_value_description_query->row['smallimage'])) ?
        $product_option_value_description_query->row['smallimage'] : null,
    'name'                    => $product_option_value_description_query->row['name'],
    'price'                   => $product_option_value['price'],
    'prefix'                  => $product_option_value['prefix']
);

语法:

(<statement> ? <case: true> : <case: false>)
(1 == 1 ? 'yes!' : 'PHP is wrong')
