Php数组显示多数组的第一个值

我知道这是一个简单的问题，但我想不出来

如何仅显示此数组中的第一个值（未上载文件）？阵列可以不同！所以$test[fileUploadFileErrorNoFile]不是解决方案

$test = Array ( [fileUploadFileErrorNoFile] => File was not uploaded 
                [fileMimeTypeNotReadable] => File is not readable or does not exist 
                [fileIsImageNotReadable] => File is not readable or does not exist 
                [fileImageSizeNotReadable] => File is not readable or does not exist 
            )

试试这个：

$test = Array (   "[fileIsImageNotReadable] => File is not readable or does not exist", "[fileImageSizeNotReadable] => File is not readable or does not exist" );


echo $test[0]; // 0 == the first value

您的阵列是这样的吗

$test = Array (
           Array(
         fileUploadFileErrorNoFile => 'File was not uploaded' ,
         fileMimeTypeNotReadable => 'File is not readable or does not exist',
         fileIsImageNotReadable => 'File is not readable or does not exist', 
         fileImageSizeNotReadable => 'File is not readable or does not exist'
         )
    );

那么答案是：

echo $test[0][fileUploadFileErrorNoFile];

数组_值（$test）[0]？数组_pop（数组_反向（$array））@Daniel1147就是这样！谢谢如果阵列不可用，此解决方案将给您一个错误empty@MarkoPaju是对的。除了OP的数组看起来和你的示例不一样，除了OP的数组和你的示例不一样
