在给定 position 的 PHP 关联数组中插入键 => 值对

Question

as mentionned in the title i'd like to add at a given position a key => value pair after checking with an if statement wether the value not empty && > 1.

The problem is when I add my key => value in the $content array the pair is added at the end of my array. I want the pair to be added after the 'version' key.

here is my foreach loop and a piece of the resulting array:

 foreach ($nodeChildrenResult['hits']['hits'] as $child) {
    
                    if ($child['_type'] === 'folder') {
    
                        $content[] = array(
    
                            'id'      => intval($child['_id']),
                            'type'    => $child['_type'],
                            'name'    => $child['_source']['node']['basename']
    
                        );
                    }else {
    
                        $content[] = array(
    
                            'id'          => intval($child['_id']),
                            'type'        => $child['_type'],
                            'name'        => $child['_source']['node']['name'],
                            'filename'    => $child['_source']['node']['basename'],
                            'extension'   => $child['_source']['node']['extension'],
                            'date'        => [
                                "import"  => $child['_source']['node']['date']['import'],
                                "update"  => $child['_source']['node']['date']['update']
                            ],
                            'version'     => $child['_source']['node']['version'],
                            'locked'      => (isset($child['_source']['node']['locked']) &&  $child['_source']['node']['locked'] == 1) ? true : false,
                            'link'        => (in_array($child['_source']['node']['extension'], $allowedExtensionForCollab) ) ? [ 'collab' => "/v2/MODULES/COLLAB/?node=".intval($child['_id'])] : [],
                            'workflow'    => $results[intval($child['_id'])]
    
                        );
    
                        if (!empty($child['_source']['node']['pageCount']) and $child['_source']['node']['pageCount'] > 1) {
                         
                            $content['pageCount'] = $child['_source']['node']['pageCount'];
    
                        }

                ]
            ],
             pageCount => 3
        ]

Answer 1

You can use a short if after you assign the version key. If the condition is false just set it to null.

<?php

$pageCount = 123;

$a[] = [
    'version' => '1.0',
    'pageCount' => (!empty($pageCount) && $pageCount > 1) ? $pageCount : null,
    'name' => 'Peter'
];

var_dump($a);

Answer 2

Oh yes I forgot to mention. If pagecount is less than one I don't want to display the key 'pageCount'. That's the crux of the problem here.

Answer 3

I've found the solution. array_filter does the job if null:

$content[] = arry_filter( array(
    
                            'id'          => intval($child['_id']),
                            'type'        => $child['_type'],
                            'name'        => $child['_source']['node']['name'],
                            'filename'    => $child['_source']['node']['basename'],
                            'extension'   => $child['_source']['node']['extension'],
                            'date'        => [
                                ...
                           'version'     => $child['_source']['node']['version'],
                           'pageCount'   => (!empty($child['_source']['node']['pageCount']) && $child['_source']['node']['pageCount'] > 1) ? $child['_source']['node']['pageCount'] : null,
