我有两个数组。 首先,我们称之为array1:
array (size=8)
0 =>
array (size=6)
'id' => string '2' (length=1)
'domacin' => string 'Man City' (length=8)
'gost' => string 'Liverpool' (length=9)
'tip' => string '1' (length=1)
'kvota' => string '1.8' (length=3)
'status' => string 'Aktivan' (length=7)
1 =>
array (size=6)
'id' => string '4' (length=1)
'domacin' => string 'Inter' (length=5)
'gost' => string 'Milan' (length=5)
'tip' => string '1' (length=1)
'kvota' => string '2.5' (length=3)
'status' => string 'Aktivan' (length=7)
第二,array2:
'id' => string '2' (length=1)
'domacin' => string 'Man City' (length=8)
'gost' => string 'Liverpool' (length=9)
'tip' => string '1' (length=1)
'kvota' => string '1.8' (length=3)
'status' => string 'Gubitan' (length=7)
我想合并这两个数组,但要使用第二个值,其中第一个id与第二个id相等。
预期结果将是:
array (size=8)
0 =>
array (size=6)
'id' => string '2' (length=1)
'domacin' => string 'Man City' (length=8)
'gost' => string 'Liverpool' (length=9)
'tip' => string '1' (length=1)
'kvota' => string '1.8' (length=3)
'status' => string 'Gubitan' (length=7)
1 =>
array (size=6)
'id' => string '4' (length=1)
'domacin' => string 'Inter' (length=5)
'gost' => string 'Milan' (length=5)
'tip' => string '1' (length=1)
'kvota' => string '2.5' (length=3)
'status' => string 'Aktivan' (length=7)
检查索引为0的状态。它从' Aktivan'(从array1)变为' Gubitan'就像我们在array2中一样。
怎么做?

foreach ($firstArr as &$item) {
if ($item['id'] == $secondArr['id']) {
$item = $secondArr;
}
}

您可以使用两个foreach循环轻松完成此操作:
foreach( $array1 as $key1=>$element1 ){
foreach( $array2 as $element2 ){
if ($element1['id'] == $element2['id'])
{
$array1[$key1]['status'] = $element2['status'];
}
}
}
