如何从阵列中选择一系列索引？

Question

在python我会这样做:

var = ["test","test1","test2","test3"];
test= var[1:3];

然后变量'test'将是["test1","test2","test3"]

我怎么能用PHP做到这一点？

Answer 1

那就是array_slice($var, 1, 3).另见:http://php.net/manual/en/function.array-slice.php.

完整的例子:

$var = array("test","test1","test2","test3");
$test = array_slice($var, 1, 3);
