Appending multiple values to associative array in PHP [duplicate] - php

Question

Merge two 2d arrays by shared column value
(6 answers)
Closed last month.
I would like to create a PHP array that will end up looking like this:
idPlayer namePlayer Points
1 John 20
2 Sam 25
3 Ben 22
But I would like to append the values not all at once:
First append the idPlayer and namePlayer
Then append the points for that idPlayer (I would have a $idPlayer variable to use each time I loop)
How could I do this in PHP?
I was thinking:
$myArray['idPlayer'] = "1";
$myArray['namePlayer'] = "John";
$myArray['Points'] = "20"
And then, how would I tell the array to go to the next row?

Answer 1

// output array
$myArray = array();
// your loop
while (something) {
// make an array for this iteration
$itarr = array();
// put stuff in it
$itarr['idPlayer'] = "1";
$itarr['namePlayer'] = "John";
$itarr['Points'] = "20"
// append it to output array using standard array indexing
$myArray[] = $itarr;
// OR, your own index
$myArray[$itarr['idPlayer']] = $itarr;
}

Answer 2

I dont know why you want to achieve such thing. But consider this example:
// like player table array initial
$players = array(
array(
'idPlayer' => 1,
'namePlayer' => 'John',
),
array(
'idPlayer' => 2,
'namePlayer' => 'Sam',
),
array(
'idPlayer' => 3,
'namePlayer' => 'Ben',
),
);
// data points to be added later (like points table)
$points = array(
array(
'idPlayer' => 1,
'Points' => 20,
),
array(
'idPlayer' => 2,
'Points' => 25,
),
array(
'idPlayer' => 3,
'Points' => 22,
),
);
$myArray = array();
foreach($players as $key => $value) {
foreach($points as $index => $element) {
// if this particular id matches the record inside points table then merge
if($value['idPlayer'] == $element['idPlayer']) {
$myArray[] = array('idPlayer' => $value['idPlayer'], 'namePlayer' => $value['namePlayer'], 'Points' => $element['Points']);
}
}
}
Should output something like: (can be used in a tabular data)
Array
(
[0] => Array
(
[idPlayer] => 1
[namePlayer] => John
[Points] => 20
)
[1] => Array
(
[idPlayer] => 2
[namePlayer] => Sam
[Points] => 25
)
[2] => Array
(
[idPlayer] => 3
[namePlayer] => Ben
[Points] => 22
)
)

Answer 3

Use the idPlayer as index:
$players = [
1 => [
'namePlayer' => 'John',
'points' => 20,
],
5 => [
'namePlayer' => 'Seth',
'points' => 25,
],
13 => [
'namePlayer' => 'Ben',
'points' => 35,
],
];
var_dump($players);

In php <5.4 use array() instead of [] constructor.
