Loop through a two-dimensional array - php

Question

I have an array that looks like this:
$array = array(
array(
"http://google.com",
"Google"
),
array(
"http://yahoo.com",
"Yahoo"
)
);
What is the simplest way to loop through it. Something like:
foreach ($array as $arr) {
// help
}
EDIT: How do I target keys, for example, I want to do:
foreach ($array as $arr) {
echo '<a href" $key1 ">';
echo ' $key2 </a>';
}

Answer 1

In order to echo out the bits you have to select their index in each array -
foreach($array as $arr){
echo ''.$arr[1].'';
}
Here is an example.

Answer 2

Use nested foreach() because it is 2D array. Example here
foreach($array as $key=>$val){
// Here $val is also array like ["Hello World 1 A","Hello World 1 B"], and so on
// And $key is index of $array array (ie,. 0, 1, ....)
foreach($val as $k=>$v){
// $v is string. "Hello World 1 A", "Hello World 1 B", ......
// And $k is $val array index (0, 1, ....)
echo $v . '<br />';
}
}
In first foreach() $val is also an array. So a nested foreach() is used. In second foreach() $v is string.
Updated according to your demand
foreach($array as $val){
echo ''.$val[1].'';
}

Answer 3

The easiest way to loop through it is:
foreach ($array as $arr) {
foreach ($arr as $index=>$value) {
echo $value;
}
}
EDIT:
If you know that your array will have always only two indexes then you can try this:
foreach ($array as $arr) {
echo "<a href='$arr[0]'>$arr[1]</a>";
}

Answer 4

First modify your variable like this:
$array = array(
array("url"=>"http://google.com",
"name"=>"Google"
),
array("url"=>"http://yahoo.com",
"name"=>"Yahoo"
));
then you can loop like this:
foreach ($array as $value)
{
echo '<a href='.$value["url"].'>'.$value["name"].'</a>'
}

Answer 5

The way to loop through is,
foreach($array as $arr)
foreach($arr as $string) {
//perform any action using $string
}
Use the first foreach loop without { } for the simplest use.
That can be the most simple method to use a nested array as per your request.
For your edited question.
Wrong declaration of array for using key.
$array = array(
"http://google.com" => "Google",
"http://yahoo.com" => "Yahoo" );
And then, use the following.
foreach ($array as $key => $value)
echo "<a href='{$key}'>{$value}</a>";
This doesn't slow down your server's performance.

Answer 6

In modern versions of php, you can assign (destructure) subarray values to variables of your choosing.
A good tutorial: https://stitcher.io/blog/array-destructuring-with-list-in-php
Code: (Demo)
$array = [
["http://example1.com", "Example 1"],
["http://example2.com", "Example 2"]
];
foreach ($array as [$key1, $key2]) {
echo "$key2\n";
}
Output:
Example 1
Example 2
To be honest, I'd probably name the variables $url and $text respectively.
