高分求助：字符串转数组

[sunrain_leo]

$str = "array(2) { [1] => array(6) { ["m_product_header_id"] => int(1) ["product_name"] => string(5) "test1" ["product_unitprice"] => int(3) ["product_point_rate"] => int(4) ["limit_nums"] => int(5) ["limit_times"] => int(6) } [2] => array(6) { ["m_product_header_id"] => int(2) ["product_name"] => string(5) "test2" ["product_unitprice"] => int(4) ["product_point_rate"] => int(5) ["limit_nums"] => int(6) ["limit_times"] => int(7) } } ";

$test = array();

现在需要将字符串$str转化到数组$test里面，形成一个2维数组。各位大侠帮忙！

没看明白
什么样的二级数组，把你想要的结果贴出来

[adverse]

字符串是怎么个规律?楼主都写明白点。

$str = "array(2) { [1] = > array(6) { ["m_product_header_id"] = > int(1) ["product_name"] = > string(5) "test1" ["product_unitprice"] = > int(3) ["product_point_rate"] = > int(4) ["limit_nums"] = > int(5) ["limit_times"] = > int(6) } [2] = > array(6) { ["m_product_header_id"] = > int(2) ["product_name"] = > string(5) "test2" ["product_unitprice"] = > int(4) ["product_point_rate"] = > int(5) ["limit_nums"] = > int(6) ["limit_times"] = > int(7) } } "; 

$reg = array(
	'/array\((\d+)\)\s*/is',
	'/\s=\s>\s/',
	'/\[(["\w]+)\]/e',
	'/int\((\d+)\)|string\((\d+)\)\s"(\w+)"/e'
);
$replace = array(
	'a:\\1:',
	'',
	'key_repalce("\\1")',
	'val_repalce("\\1", "\\2", "\\3")'
);

function key_repalce($e) {
	if(!$e) return;

	if(is_numeric($e)) {
		return 'i:'.$e.';';
	} elseif(is_string($e)) {
		$e = str_replace('"', '', $e);
		return 's:'.strlen($e).':"'.$e.'";';
	}
}

function val_repalce($e_int, $e_strlen, $e_str) {
	if($e_int) {
		return 'i:'.$e_int.';';
	} elseif($e_strlen) {
		return 's:'.$e_strlen.':"'.$e_str.'";';
	}
}

$serialize_str = str_replace(' ', '', preg_replace($reg, $replace, $str));

print $serialize_str;
print "\n";
print_r(unserialize($serialize_str));

上面的第一句代码因该是:

$str = 'array(2) { [1] = > array(6) { ["m_product_header_id"] = > int(1) ["product_name"] = > string(5) "test1" ["product_unitprice"] = > int(3) ["product_point_rate"] = > int(4) ["limit_nums"] = > int(5) ["limit_times"] = > int(6) } [2] = > array(6) { ["m_product_header_id"] = > int(2) ["product_name"] = > string(5) "test2" ["product_unitprice"] = > int(4) ["product_point_rate"] = > int(5) ["limit_nums"] = > int(6) ["limit_times"] = > int(7) } } '; 

楼主居然用了双引号,检测了一下才发现!

[faisun]

$str = 'array(2) { [1] = > array(6) { ["m_product_header_id"] = > int(1) ["product_name"] = > string(5) "test1" ["product_unitprice"] = > int(3) ["product_point_rate"] = > int(4) ["limit_nums"] = > int(5) ["limit_times"] = > int(6) } [2] = > array(6) { ["m_product_header_id"] = > int(2) ["product_name"] = > string(5) "test2" ["product_unitprice"] = > int(4) ["product_point_rate"] = > int(5) ["limit_nums"] = > int(6) ["limit_times"] = > int(7) } } ';

$test = array();

如果你对 $str 这个串绝对信任的话:

eval("\$test = $str;");

[faisun]

你可以用 var_dump 和 eval 实现 array <=> string 的转换;
安全一点,也可以用
serialize 和 unserialize 实现 array <=> string 的转换

[faisun]

错了是 var_export 和 eval 实现 array <= > string 的转换;

[总哈哈]

哪是键，哪是值，楼主都没有说清楚，就给个这叫别人转呀？我是看不懂了，等高手。。。。

[tony-杨]

貌似是var_dump打印出来的数组变量信息

[Aylazhang]

好像是要将var_dump 的结果反转回原数组。

[hejunbin]

哈哈 要有 re_var_dump函数就好了！！！O.o
