我有一个代码如下,我不知道什么类型的数据变量$ACTIVITYGROUPS []有,我怎么读它？
$ACTIVITYGROUPS[] = saprfc_table_read ($fce,"ACTIVITYGROUPS",$i);
当我做print_r(saprfc_table_read($fce,“ACTIVITYGROUPS”,$i);我得到了一堆没有任何分隔符的数组,不知道如何精确数据.有人可以告诉我它在上面的句子中做了什么？
这是print_r(saprfc_table_read($fce,$i);结果给了我：
Array (
[AGR_NAME] => Y:SECURITY_DISPLAY
[FROM_DAT] => 20080813
[TO_DAT] => 99991231
[AGR_TEXT] => Security Display - Users & Roles
[ORG_FLAG] => C
)
Array (
[AGR_NAME] => Y:SECURITY_ADMIN_COMMON
[FROM_DAT] => 20080813
[TO_DAT] => 99991231
[AGR_TEXT] => Security Administrator
[ORG_FLAG] => C
)
Array (
[AGR_NAME] => Y:LOCAL_TRANSPORT
[FROM_DAT] => 20090810
[TO_DAT] => 99991231
[AGR_TEXT] => Transport into target client - DEV system only
[ORG_FLAG] =>
)
[]表示push – 将给定的参数作为数组末尾的新元素.这意味着$ACTIVITYGROUPS是一个数组*.
$arr = array(); $arr[] = 1; // Put 1 in position 0 $arr[] = "a"; // Put "a" in position 1 $arr[] = array() // Put a new,empty array in position 2
正如PHP文档所述,array_push与[]具有相同的效果.
*如果它不是数组,使用[]将给出语法错误：
Warning: Cannot use a scalar value as an array in test.PHP on line 4
