Array to string conversion error when using implode
提问by Francesca
I'm confused about an error I am getting stating Array to string conversion
我对我所陈述的错误感到困惑 Array to string conversion
The reason I'm confused is I'm trying to do exactly that, convert an array to a string, using implodewhich according to the manual should allow me to convert my array into a string. So why am I getting an error?
我感到困惑的原因是我正试图做到这一点，将数组转换为字符串，implode根据手册使用它应该允许我将数组转换为字符串。那么为什么我会收到错误消息？
var $matchesis an array. $error_cis the var I want to store the string.
var$matches是一个数组。$error_c是我要存储字符串的 var。
print_r($matches); // prints the array correctly
$error_c = implode(',', $matches);
echo $error_c;
Outputs simply arrayand gives:
简单地输出array并给出：
Notice: Array to string conversion in ...
The manual states that implode — Join array elements with a stringso why do I get an error when I try to do it?
手册指出，implode — Join array elements with a string为什么我尝试这样做时会出错？
Edit: this is the output I get from $matches
编辑：这是我得到的输出 $matches
Array ( [0] => Array ( [0] => C [1] => E [2] => R [3] => R [4] => O [5] => R [6] => C [7] => O [8] => N [9] => T [10] => A [11] => C [12] => T [13] => S [14] => U [15] => P [16] => P [17] => R [18] => E [19] => S [20] => S [21] => E [22] => D ) )

You have an array of arrays... Try this:
你有一个数组数组......试试这个：
$error_c = implode(',', $matches[0]);
回答by Mad Angle
$error_c = implode(',', $matches[0]);
echo $error_c;
because your arraycontains arraysinside
因为你array包含arrays在里面
回答by Enrique Mu?oz Rodas
Do that:
去做：
print_r($matches); // prints the array correctly
$error_c = implode(',', $matches[0]);
echo $error_c;
回答by Mike
You may use array_values()for array of arrays
您可以array_values()用于数组数组
e.g. implode (",", array_values($array))
例如 implode (",", array_values($array))

To just put whatever data is in the array into a string, try this
要将数组中的任何数据放入字符串中，试试这个
function whatever_to_string($in){
ob_start();
print_r($in);
return ob_get_clean();
}
The 'ob_*' functions control the output buffer.
'ob_*' 函数控制输出缓冲区。
