显示爆炸阵列[关闭]

Question

This is a very noob question. The previous developer has coded the lines as below

$a = array("30"=>"ok","40"=>"yes");

$b = "hi";

$c = $a."|".$b;

$d = explode("|",$c);

print_r($d[0]);

How can I display the array array("30"=>"ok","40"=>"yes")? print_r($d[0]); seems to print just array

Answer 1

This prints "array" instead of the actual array values is because this line:

$c = $a."|".$b;

What you're doing is saying:

$c = [array] + [string] + [string];

which will force array to be transformed into a string, which is just "array"

if you really want a | separated string of array indices, you could theoretically do this:

$c = implode("|",$a)."|".$b;

But the real best solution here would be to add something to the array before exploding the array:

$a['50'] = 'hi';
$d = explode("|", $c);
