I need to access the first row of an array but not like this:

print_r($array[0]) ;

something like this and be built-in :

echo first($array) ;

is there anything like that in php?

有帮助吗?

解决方案

reset($array) will move the internal array pointer to the first element and return that element as well.

Note that "the first element" not necessarily means the element with index 0. It means the first element that got added to the array:

$array[1] = "foo";
$array[0] = "bar";
$first = reset($array); // foo

You might want to sort the array before fetching the "first" element.

其他提示

$first_value_of_array = reset($array); // First Element's Value
$first_key_of_array = key($array); // First Element's Key

Hope this helps. :)
