I don't know how foreach traverses such an array. for example, there is an array like this: array (4) & nbsp ;{& nbsp; & nbsp; ["title"] = & gt; & nbsp; array (9) & nbsp; {& nbsp; [0] = & gt; & nbsp; & nbsp doesn't understand how foreach traverses such an array in this way
For example, there is an array:
Array (4 ){
["Title"] =>
Array (9 ){
[0] =>
String (3) "Title 1"
[1] =>
String (3) "title 2"
[2] =>
String (3) "title 3"
[3] =>
String (3) "title 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 arrays
}
I want to traverse the data like this:
Title 1
85.00
Title 2
155.00
Title 3
49.00
Title 4
75.00
How should I write it?
Foreach ($ arr as $ key => $ value)
{
Foreach (it won't be written)
{
Echo'
';
Echo '';
Echo '';
Echo $ title;
Echo''. $ Price .'';
Echo '';
Echo'';
}
} Shared :?? Array (9 )? {???? [0] => ???? String (3 )? "Title 1 "???? [1] => ???? S... 'data-pics = ''>
------ Solution --------------------
For data Reference
$ Ar = array (
"Title" => array ("title 1", "title 2", "title 3", "title 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;
}Solution 2
foreach(array_map(null, $ar['id'], $ar['pic'], $ar['title'], $ar['price']) as $i=>$r) {
echo <<< HTML
$r[2]
$r[3]
HTML;
}Both outputs
Title 1
85.00
Title 2
155.00
Title 3
49.00
Title 4
75.00
