我如何在任何位置插入一个新项目到数组中，例如在数组中间？ You may find this a little more intuitive. It only requires one function call to array_splice : $original = array( 'a', 'b', 'c', 'd', 'e' ); $inserted = array( 'x' ); // Not necessarily an array array_splice( $original, 3, 0, $inserted ); // splice in at position 3 // $original is now a b c x d e A function that can insert at both inte
我如何在任何位置插入一个新项目到数组中，例如在数组中间？ 你可能会发现这更直观一些。 它只需要对array_splice一次函数调用： $original = array( 'a', 'b', 'c', 'd', 'e' ); $inserted = array( 'x' ); // Not necessarily an array array_splice( $original, 3, 0, $inserted ); // splice in at position 3 // $original is now a b c x d e 可以在整数和字符串位置插入的函数： /** * @param array $array *
Possible Duplicate: + operator for array in PHP? If $a and $b are both arrays, what is the result of $a + $b ? http://www.php.net/manual/en/language.operators.array.php Union of $a and $b. The + operator appends elements of remaining keys from the right handed array to the left handed, whereas duplicated keys are NOT overwritten. <?php $a = array(1, 2, 3); $b = array(4, 5, 6); $c = $
可能重复： PHP中的数组运算符？ 如果$a和$b都是数组， $a + $b的结果是什么？ http://www.php.net/manual/en/language.operators.array.php Union of $a and $b. +操作符将右手阵列中剩余键的元素附加到左手，而重复键不会被覆盖。 <?php $a = array(1, 2, 3); $b = array(4, 5, 6); $c = $a + $b; print_r($c); 结果在我这里： Array ( [0] => 1 [1] => 2 [2] => 3 ) 但： <?php $a
Question: With Apache/PHP, can I use php_admin_* flags and ini_set() in conjunction to show PHP errors locally and hide them remotely without any changes to the remote configuration? The idea is to turn show error flags on in the local httpd.conf file, and off in both the local and remote index file. This is useful where there is no access to httpd.conf or php.ini files remotely. Local httpd.
问题：使用Apache / PHP，我可以使用php_admin_ *标志和ini_set（）结合使用，以在本地显示PHP错误并远程隐藏它们，而不需要对远程配置进行任何更改？ 这个想法是在本地httpd.conf文件中打开显示错误标志，并关闭本地和远程索引文件。 这在远程无法访问httpd.conf或php.ini文件的情况下非常有用。 本地httpd.conf文件 - 打开错误显示： php_admin_flag display_startup_errors on php_admin_value display_errors on php_adm

I am using this module PHP trader. I am not able to understand what "Predefined constant" means. Should we define these before we call the functions? Should we define them as numbers, or is there no need to mention them before calling the functions? http://php.net/manual/en/trader.constants.php: Predefined Constants - The constants below are defined by this extension, and will o
我正在使用这个模块的PHP交易者。 我无法理解“预定义常量”的含义。 在我们调用函数之前我们应该定义这些吗？ 我们应该将它们定义为数字，还是在调用函数之前不需要提及它们？ http://php.net/manual/en/trader.constants.php： 预定义常量 - 下面的常量是由这个扩展定义的，并且只有在扩展已经被编译为PHP或者在运行时动态加载时才可用。 不，你不需要定义任何东西。 预定义的常量由扩展名定义，以便您可以使用符号

I wrote an error handler to handle different kind of errors in php(even parse errors etc.). Question: As I now can detect an errortype(the constant) it is necessary to identify which errors I should allow or not and in which case do a gentle shutdown. If I look at http://www.php.net/manual/en/errorfunc.constants.php I see all the different constants for different kind of errors. The questi
我写了一个错误处理程序来处理不同类型的错误（甚至解析错误等）。 题： 正如我现在可以检测到一个errortype（常量），有必要确定哪些错误我应该允许或不允许，并在这种情况下轻轻关机。 如果我看看http://www.php.net/manual/en/errorfunc.constants.php，我会看到不同类型的错误的所有不同的常量。 问题是： 1）这些常量之间是否存在某种错误处理关系。 让我说超过一个水平，我知道我不想打印在我的屏幕上的错误等？
