How to Define an Array in PHP Using Key Value?

[Rodney]

Hello,

I want to define an array in PHP using key value pairs as follows:

$myArray = (
'item1' => 'value1',
'item2' => 'value2',
'item3' => 'value3'
);

But whenever I need to use one of the stored value in this array using numeric index like,$myArray[1] It shows the following error:

Notice: Undefined offset: 1

Anyone have a solution?

You can use array_keys when you actually need it:

$arrayKeys = array_keys($myArray);

echo $myArray[$arrayKeys[0]];

Or in a foreach:

foreach($myArray as $key=>$value) {
//$ key stores item1,item2,item3
//$value stores $value1, value2,value3
}

Hi Rodney,
You can pass your array by using array_values first to get what you want:

echo array_values($myArray)[1];

PHP: array_values - Manual

array_values() returns all the values from the array and indexes numerically.

Would not you convert the entire array before echoing them?

It depends on your need. If you just need one value, then it is easier.
