Question

我有一个像以下一样的字符串...

Array ([product_name] => this is a product [product_desc] => some descripyion [cat_id] => 3)

这看起来像一个数组，但这是一个字符串。如果我使用echo，那么它会打印相同的结果。

$someVariable = "Array ([product_name] => this is a product [product_desc] => some descripyion [cat_id] => 3)";

echo $someVariable;

结果：

Array ([product_name] => this is a product [product_desc] => some descripyion [cat_id] => 3)

我需要它转换为数组，以便我可以执行以下操作..

echo $someVariable['product_name'];

并获得以下结果

this is a product

有没有办法做到这一点？

由于

Answer 1

serialize数据：

<input type="hidden" name="data" valaue='<?php print_r(serialize($yourData));?>'>

然后unserialize：

<?php 
    $youralldata = unserialize($_POST['data']);
    print_r($youralldata);
?>

Answer 2

$someVariable = "Array ([product_name] => this is a product [product_desc] => some descripyion [cat_id] => 3)";

preg_match_all('/\[(.*?)\]/', $someVariable, $keys);
preg_match_all('/=> (.*?) ?[\[|\)]/', $someVariable, $values);

$someVariable = array_combine($keys[1], $values[1]);

这会将字符串转换回数组。

Answer 3

 function stringToArray($string){
    $pattern = '/\[(.*?)\]|=>\s+[\w\s\d]+/';
    preg_match_all($pattern,$string,$matches);
    $result = array();
    foreach($matches[0] as $i => $match){
        if($i%2 == 0){
                    $key = trim(str_ireplace(array("[","]"),"",$match));
            $value = trim(str_ireplace(array("=>"),"",$matches[0][$i+1]));
            $result[$key] = $value;
        }
    }
    return $result;
}

$someVariable =   "Array ([product_name] => this is a product [product_desc] => some descripyion [cat_id] => 3)";

$someVariable = stringToArray($someVariable);

echo $someVariable['product_name'];

使用php进行字符串转换
