复制代码 代码如下:
function getarray_postgresql($arraystr)
{
$regx1 = '/^{(.*)}$/';
$regx2 = "/\"((\\\\\\\\|\\\\\"|[^\"])+)\"|[^,]+/";
$regx3 = '/^[^"].*$|^"(.*)"$/';
$match = null;
preg_match( $regx1,$arraystr,$match);
$str = $match[1];
preg_match_all($regx2, $str,$match);
$items = $match[0];
$array = array();
$count = count($items);
for($index = 0; $index {
preg_match($regx3, $items[$index],$match);
$array[$index]=end($match);
}
return $array;
}
在PHP从postgresql中读取的数据都是字符串的,一般的数据还好处理,但是postgresql有一种数组型的数据,而如果我们的数组是字符串的,前且,里面有逗号或斜线也是可能的,这就给我们读取带来了一定的麻烦,上面的函数是我奋斗了几个小时写出来的。尽可能的考虑到了斜线,逗号,引号的存在。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
