Question

我正在尝试使用逗号分隔的值列表：

$products = array( array( Title => "rose", 
                      Price => 1.25,1.31,1.54,1.39
                      //comma separated list
                      Type => dropdown
                    ),
               array( Title => "daisy", 
                      Price => 0.75,
                      Type => text_field,
                    ),
               array( Title => "orchid", 
                      Price => 1.15,
                      Type => text_field
                    )
             );

我有没有办法在php中的数组中用逗号分隔列表？

$products = array( array( Title => "rose", 
                      Price => array(1.25,1.31,1.54,1.39)
                      //comma separated list
                      Type => dropdown
                    ),
               array( Title => "daisy", 
                      Price => 0.75,
                      Type => text_field,
                    ),
               array( Title => "orchid", 
                      Price => 1.15,
                      Type => text_field
                    )
             );

如果您将逗号分隔列表作为字符串，并希望将其表示为数组，则可以使用explode

$myString = "1,2,3,4,5";
$myArray = explode(',',$myString);

Answer 3

是的，您必须将“1.25,1.31,1.54,1.39”分配给ARRAY作为字符串（附带“”）

                      Type => "dropdown"
                    ),
               array( Title => "daisy", 
                      Price => 0.75,
                      Type => text_field,
                    ),
               array( Title => "orchid", 
                      Price => 1.15,
                      Type => text_field
                    )
             );

Answer 4

您不能为数组指定逗号分隔列表，因为指针只能指向内存而不是结构。您可以使用另一个数组或字符串来解决此问题。如果要使用字符串，则需要使用函数explode（）来分隔字符串。

这是允许在数组中
