Massiivit\u00fckki (array_chunk<\/code>) kasutades saame massiivi h\u00f5lpsalt jagada mitmem\u00f5\u00f5tmeliseks massiiviks (massiivide massiiviks).<\/p>\n

Massiivi t\u00fckki funktsiooni saab kasutada massiivi v\u00e4iksemateks osadeks jagamiseks, v\u00f5ib-olla t\u00f6\u00f6tlemise h\u00f5lbustamiseks.<\/p>\n

P\u00f5hiline n\u00e4ide<\/h2>\n

Eeldades, et seadistame massiivi alltoodud koodin\u00e4ite kohaselt ($array<\/code>real 1), saame selle massiivi t\u00fckeldada uueks mitmem\u00f5\u00f5tmeliseks massiiviks, kasutades array_chunk<\/code>real 9 olevat funktsiooni.<\/p>\n

Selle koodi k\u00e4ivitamine tooks real 15 tulemuseks mitmem\u00f5\u00f5tmelise massiivi.<\/p>\n

Funktsioon array_chunk<\/code>aktsepteerib kolme parameetrit, $array<\/code>ja $chunk<\/code>( $preserve_keys<\/code>valikuline, vaikimisi false). Need on j\u00e4rgmised:<\/p>\n
    \n
  1. Parameeter $array<\/code>aktsepteerib massiivi ja on esialgne massiiv, mida soovime teisendada.<\/li>\n
  2. Aktsepteerib t\u00e4isarvu ja $chunk<\/code>on arv, mida kasutame $array<\/code>selle v\u00e4\u00e4rtuse osadeks jagamiseks.<\/li>\n
  3. Valikuline $preserve_keys<\/code>parameeter aktsepteerib t\u00f5ev\u00e4\u00e4rtust ja s\u00e4ilitab massiivi v\u00f5tmed, kui true<\/code>.<\/li>\n<\/ol>\n
    Funktsioonid ja konkreetsed n\u00e4ited<\/h2>\n
    S\u00e4ilitage v\u00f5tmed<\/h3>\n
    Parameetrit uurides $preserve_keys<\/code>alustab meie eelmine n\u00e4ide iga pesastatud massiivi indeksi 0-st. Kui aga l\u00e4heksime true<\/code>sellesse parameetrisse, j\u00e4\u00e4ks esialgse massiivi esialgne indeks puutumata:<\/p>\n
    $array = [\n    'Post 0', \n    'Post 1', \n    'Post 2', \n    'Post 3', \n    'Post 4', \n    'Post 5',\n];\n$chunked_array = array_chunk( $array, 2, true );\nprint_r( $chunked_array ); \/\/ Output the new array.\n\n\/**\n * Output:\n *\n * Array\n * (*   [0] => Array\n * (*          [0] => Post 0\n *          [1] => Post 1\n *) *   [1] => Array\n * (*          [2] => Post 2\n *          [3] => Post 3\n *) *   [2] => Array\n * (*           [4] => Post 4\n *           [5] => Post 5\n *) *)\n **\/\n<\/code><\/pre>\n
    V\u00e4ljundis on v\u00f5tmed n\u00fc\u00fcd j\u00e4rjestikused, nagu need oleksid algses massiivis (0, 1, 2, 3\u2026).<\/p>\n
    S\u00e4ilitage v\u00f5tmed, kui originaalmassiivil on nimega v\u00f5tmed<\/h3>\n
    Kui meie algsel massiivil on nimelised v\u00f5tmed, saame v\u00f5tmed s\u00e4ilitada, et neid meie t\u00fckeldatud massiivis s\u00e4ilitada.<\/p>\n
    J\u00e4rgmises n\u00e4ites on sellega natuke nalja. Oletame, et oleme kuidagi saanud massiivi, kus on segatud m\u00f5ned postituse ID-d ja postituste nimed.<\/p>\n
    V\u00f5iksime kasutada array_chunk<\/code>parameetrit $preserve_keys<\/code>, true<\/code>et jagada need \u00fcksikuteks postitusteks.<\/p>\n
    $array = [\n    'id_0'   => '10', \n    'name_0' => 'Post 1', \n    'id_1'   => '20', \n    'name_1' => 'Post 2', \n    'id_2'   => '30', \n    'name_2' => 'Post 3',\n];\n$chunked_array = array_chunk( $array, 2, true);\nprint_r( $chunked_array ); \n<\/code><\/pre>\n
    Kui teil on selle massiiviga endiselt l\u00f5bus, kujutame ette, kuidas saaksime silmust l\u00e4bi vaadata $chunked_array<\/code>ja v\u00e4ljastada ainult nimed.<\/p>\n
    foreach( $chunked_array as $key => $nested_array) {\n    echo $nested_array[ 'name_'. $key ]. PHP_EOL;\n}\n<\/code><\/pre>\n
    Suure massiivi t\u00fckeldamine t\u00f6\u00f6tlemiseks.<\/h3>\n
    Kui meil on v\u00e4ga suur massiiv, saame array_chunk<\/code>selle jagada v\u00e4iksemateks t\u00fckkideks, mida saaksime seej\u00e4rel eraldi salvestada. Vaatame, kuidas saaksime seda WordPressis teha:<\/p>\n
    $original_array = [...]; \n$post_id        = get_the_ID();\n$chunked_array  = array_chunk( $original_array, 10, true );\n\nforeach( $chunked_array as $key => $array) {\n    update_post_meta( \n        $post_id,\n        '_wc_chunked_array_partial_'. $post_id,\n        $array\n    );\n}\n<\/code><\/pre>\n
