Php 如何删除阵列中的会话？

我需要为我的网站写一个产品篮，但我不能从数组中删除索引。我在下面写了一个数组索引：

Array
(
    [0] => Array
        (
            [urun_id] => 174
            [urun_adi] => ANT-5527N - Dual Polarity Parabolic Dish Anten 4.8-6.1Ghz 27Dbi
            [urun_fiyati] => 672
            [urun_fiyati_kur] => TL
            [urun_adeti] => 1
        )

    [1] => Array
        (
            [urun_id] => 149
            [urun_adi] => Cloud Router Switch 16x SFP+(10G ) 1Gbit Eth 
            [urun_fiyati] => 1683
            [urun_fiyati_kur] => TL
            [urun_adeti] => 1
        )

    [2] => Array
        (
            [urun_id] => 175
            [urun_adi] => ANT-5531N - Dual Polarity Parabolic Dish Anten 4.8-6.1Ghz 31Dbi
            [urun_fiyati] => 694
            [urun_fiyati_kur] => TL
            [urun_adeti] => 1
        )

)

您可以为此使用：

unset（$array[2]）删除索引为2的元素作为答案。我理解。如何使用foreach获取数组密钥？如果我能得到一个数组键。我能做到。foreach（$_SESSION[“urun_listesi”]作为$urun）{echo（'.$urun[“urun_adi”]”..$urun[“urun_adeti”]”..$urun[“urun_fiyati”]”.$urun[“urun_fiyati_kur”]”回音（“”）；打印（$_SESSION[“urun_listei”]）；回音（“”；}输出：数组（[174]>Array（[urun(id]=>174;=>ANT-5527N-双极性抛物面天线4.8-6.1Ghz 27Dbi[urun_fiyati]=>672[urun_fiyati_kur]=>TL[urun_adeti]=>1[175]=>阵列（[urun_id]=>174[urun_adi]=>ANT-5527N-双极性抛物面天线4.8-6.1Ghz 27Dbi[urun_fiyati]=>672[urun_fiyati_kur]=>TL[urun_adeti]=>1）
