PHP检查值是否存在于另一个数组中 [英] php check if value exsist in array, in another array

问题描述

我有一个数组dataImages，它保存图像信息的数组，看起来像这样

I have a array dataImages which holds the arrays of image informations and looks like this

Array ( 
    [0] => Array ( 
        [id] => 104 
        [name] => sample-large-Test-1-a52d268be9ad9c.png 
        [user] => 31 
        [main_image] => 1 
    ) 
    [1] => Array ( 
        [id] => 105 
        [name] => sample-large-Test-1-a52d268bee6ba5.jpg 
        [user] => 31 
        [main_image] => 0 
    ) 
    [2] => Array ( 
        [id] => 106 
        [name] => sample-large-Test-1-a52d268bf4c457.jpg 
        [user] => 31 
        [main_image] => 0 
    ) 
) 

如何检查数组dataImages中是否为带有main_image === 1的图像?如何显示该图像的数据?

How can i check if in array dataImages is an image with main_image === 1 and how can i show data for that image?

推荐答案

您还可以循环执行此操作:

You can do this in loop also:

foreach ($dataImages as $image){
    if ($image['main_image']) print_r($image)
}
