What is this?

This is a collection of questions that come up every now and then about syntax in PHP. This is also a Community Wiki, so everyone is invited to participate in maintaining this list.

Why is this?

It used to be hard to find questions about operators and other syntax tokens.¹
The main idea is to have links to existing questions on Stack Overflow, so it's easier for us to reference them, not to copy over content from …

在PHP中使用什么更好的附加数组成员:

$array[] = $value;

要么

array_push($array, $value);

虽然手册说你最好避免函数调用,但我读$array[]的速度要慢得多array_push().有没有人有任何澄清或基准？

我有一个如下代码,我不知道什么类型的数据变量$ACTIVITYGROUPS[]有什么,我怎么读它？

$ACTIVITYGROUPS[] = saprfc_table_read ($fce, "ACTIVITYGROUPS", $i);

当我这样做时,print_r(saprfc_table_read ($fce, "ACTIVITYGROUPS", $i);我得到了一堆没有任何分隔符的数组,并且不确定如何精确数据.谁可以告诉我它在上面的句子中做了什么？

print_r(saprfc_table_read ($fce, "ACTIVITYGROUPS", $i);结果给出了以下结果:

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 - …

将变量添加到数组时哪个更快？

1. $ variable [] = $ newValue;
2. array_push($变量$ NEWVALUE);

请注意两者之间的区别(如果有的话).

我有这样的数组(仅一维):

$arr = array('one', 'two', 'three', 'foo', 'bar', 'etc');

现在我需要一个for()创建新数组的循环$arr,如下所示:

$newArr = array('one', 'onetwo', 'onetwothree', 'onetwothreefoo', 'onetwothreefoobar', 'onetwothreefoobaretc');

似乎很简单,但我无法弄清楚.

提前致谢!
