I don't know how foreach can traverse such an array like this.

For example, there is an array such as:
Array (4) {
["title"]=>
Array (9) {
[0]=>
String (3) "Heading 1"
[1]=>
String (3) "Heading 2"
[2]=>
String (3) "Heading 3"
[3]=>
String (3) "Heading 4"
}
["id"]=>
Array (9) {
[0]=>
String (1) "N1"
[1]=>
String (1) "N2"
[2]=>
String (1) "N3"
[3]=>
String (1) "N4"
}
["Pic"]=>
Array (9) {
[0]=>
String (4) "1.jpg"
[1]=>
String (4) "2.jpg"
[2]=>
String (4) "3.jpg"
[3]=>
String (4) "4.jpg"
}
["Price"]=>
Array (9) {
[0]=>
String (5) "85.00"
[1]=>
String (6) "155.00"
[2]=>
String (5) "49.00"
[3]=>
String (5) "75.00"
}
.... More groups

}

I want to iterate through the data in this way:

Title 1
85.00

Title 2
155.00

Title 3
49.00

Title 4
75.00

What should be written in it?
foreach ($arr as $key = $value)
{
foreach (it won't be written inside)
{
Echo '

';
Echo ';
Echo ';
echo $title;
Echo '. $price. ';
Echo ';
Echo '

';
}
}

Reply to discussion (solution)

foreach ($value as $k = $v)
Red is the same value as the previous layer, and blue is different.

You this array structure, it is best to use a two-dimensional array class I sent before to do a row and column conversion, it is much simpler, the output is traversed once can be

Where is it? Link can you send me a bit?

I send a few posts, you can search to find

In fact, if you can confirm the array of key values corresponding, you can also directly traverse the two-dimensional key value
for ($i =0; $i <= Two-dimensional key value Max; $i + +) {
echo $array ["title"] [$i];
......
}

foreach ($value as $k = $v)
Red is the same value as the previous layer, and blue is different.
This comes out of all the data.
The effect is this:
Title 1
Title 2
Title 3
Title 4
N1
N2
N3
N4
1.jpg
2.jpg
3.jpg
4.jpg
85.00
155.00
49.00
75.00

Just took out all the data, not what I wanted.
Title 1,n1,1.jpg,85.00
Title 2,n2,2.jpg,155.00
Title 3,n3,3.jpg,49.00
Title 4,n4,4.jpg,75.00

Title 1,n1,1.jpg,85.00
Title 2,n2,2.jpg,155.00
Title 3,n3,3.jpg,49.00
Title 4,n4,4.jpg,75.00
That's what your data structure is, so let's change it, or write it in # #

For data

$ar = Array ("title" = = Array (  "Heading 1", "Title 2", "Heading 3", "Heading 4"),  "id" = = Array ("N1", "N2", "N3", "N4"),  "pic" = = Array ("1.jpg", "2.jpg", "3.jpg", "4.jpg"),  "price" = = Array ("85.00", "155.00", "49.00", "75.00"),);

Method 1:

foreach ($ar [' id '] as $i = + $r) {  echo <<< HTML
{$ar [' title '] [$i]} {$ar [' price '] [$i]}
HTML;}

Scenario 2

foreach (Array_map (null, $ar [' id '], $ar [' pic '], $ar [' title '], $ar [' Price ']) as $i + = $r) {  echo <<< HTML
$r [2]$r [3]
HTML;}

can be output

Title 185.00
Title 2155.00
Title 349.00
Title 475.00
