Unable to iterate on the content of an array - php

Question

I have an array which contents data that I can see on doing a var_dump() but I am unable to iterate through its content using foreach()
The var_dump() generates the following output
array(4) { [0]=> array(1) { [0]=> string(5) "Admin" } [1]=> array(1) { [0]=> string(4) "rick" } [2]=> array(1) { [0]=> string(6) "techbr" } [3]=> array(1) { [0]=> string(7) "testdom" } }
I want to be able to get the content of this array and store it in another.
Currently I am using the following code
$empList = array();
$empList = emp_list($mysqli);
var_dump($empList);//This generated the above output
foreach ($empList as $value)
{
echo $value."<br>";
}
Output of the echo is this
Array
Array
Array
Array
How do I sort this out?
Thank you for your suggestions I have modified the code this way
$i=0;
$empList = array();
$tempList = array();
$tempList = emp_list($mysqli);
foreach ($tempList as $value)
{
$empList[$i] = $value[0];
$i++;
}
Now the $empList array stores stuff in the correct format

Answer 1

It has an array inside another array so, use two foreach loops
$empList = array();
$empList = emp_list($mysqli);
foreach ($empList as $value)
{
foreach ($value as $temp)
{
echo $temp."<br>";
}
}

As u_mulder says in the comments on your question, your array isn't an array of strings - it's an array of more arrays. var_dump() is designed to deal with complicated nested contents, but echo can't print arrays - that's why it's just telling you that each item in $empList is an array, and not what its contents are.
If you wanted to get the content out of a specific array in $empList you'd need to access it by its index key, with something like:
$first = $empList[0];
foreach ($first as $value) {
echo $value."<br>";
}
Or if you wanted to iterate through them all you could just put two foreach loops one inside the other.
