Loop through Arrays with PHP

  • 772

I make a query via API and as a response I get a JSONwhich I store in a variable and convert it into an Array:

$items = json_decode( $access__resultado, true );

I print a part of the Array (the one that interests me) as follows:

echo "<pre>";
print_r( $items["accesses"] );
echo "</pre>";

And it gives me the following result:

Array (
    [0] => Array (
        [access_id] => 8o5THPq8mofa
    )
    
    [1] => Array (
        [access_id] => mmBAHc107Unp
    )
    
    [2] => Array (
        [access_id] => gDDOyPQIXH60
    )
)

How can I loop through it to get the value of each access_id? I have tried the following ways, but it doesn't show me anything:

$accesses = $items["accesses"]; // Opción 1
$accesses = $items->accesses; // Opción 2
foreach ( $accesses as $val ) {
    echo $value["access_id"]; // Opción 1
    echo $value->access_id; // Opción 2
}
php

    In the foreach loop, the first $accesses element is the sub-arrsy you want to loop through. On the right side of the 'as' you define the variable $val, which is going to be each element. In this case each $val contains an access_id key.

    Therefore, within your loop you must access $val and not $value, which is not defined in your example. Put inside your loop:

    echo $val['access_id'];
