Nested 'foreach' for multidimensional array - php

Question

<?php
$p_23 = array("Name"=>"XYZ","Age"=>"12");
$a_23 = array("Class"=>"5","Sec"=>"A");
$r_23 = array("Personal"=>$p_23,"Academic"=>$a_23);
$p_24 = array("Name"=>"ABC","Age"=>"14");
$a_24 = array("Class"=>"6","Sec"=>"B");
$r_24 = array("Personal"=>$p_24,"Academic"=>$a_24);
$stud = array("23"=>$r_23,"24"=>$r_24);
foreach ($stud as $key => $value) {
echo $value;
}
?>
Using echo is giving error,
previous issue resolved, expanding my question now.
now i want this multi dimensional array to print like below using html tags
#Roll 23#
##Academic##
-Class=>5
-sec=>B
Personal
-Name=>YXZ
-Age=>12
#Roll 24#
##Academic##
-Class=>6
-sec=>A
Personal
-Name=>ABC
-Age=>12
--Nested foreach part with HTML tags--
foreach ($stud as $key => $value) {
echo "<h1>Roll $key</h1>";
echo "<ol>";
foreach ($r_23 as $key => $value) {
echo "<h2>$key</h2>";
echo "<ul>";
foreach ($p_23 as $key => $value){
echo "<li>$key => $value</li>";}
echo "</ul>";}
echo "</ol>";
but it is showing the same value for both academic and personal keys, which i dont exactly want. Thank u!!

Answer 1

$value is an array, echo will only print strings, you need to either JSON encode your $value and echo it or use var_dump. If your intended output was more complex than this then you would need to expand on your question.

Answer 2

Well, its a multi-dimensional array, so you need more foreach()
Here is the updated code:
<?php
$p_23 = array("Name"=>"XYZ","Age"=>"12");
$a_23 = array("Class"=>"5","Sec"=>"A");
$r_23 = array("Personal"=>$p_23,"Academic"=>$a_23);
$p_24 = array("Name"=>"ABC","Age"=>"14");
$a_24 = array("Class"=>"6","Sec"=>"B");
$r_24 = array("Personal"=>$p_24,"Academic"=>$a_24);
$stud = array("23"=>$r_23,"24"=>$r_24);
foreach ($stud as $key => $value) {
foreach($value as $k => $v){
foreach($v as $kk => $vv) {
echo $vv;
}
}
}
?>
And this is your multi-dimensional array:
Array
(
[23] => Array
(
[Personal] => Array
(
[Name] => XYZ
[Age] => 12
)
[Academic] => Array
(
[Class] => 5
[Sec] => A
)
)
[24] => Array
(
[Personal] => Array
(
[Name] => ABC
[Age] => 14
)
[Academic] => Array
(
[Class] => 6
[Sec] => B
)
)
)
