陣列在PHP

Question

合併我有兩個陣列：

數組1：

array (size=3) 
    0 => 
    array (size=5) 
     'id' => string '11' (length=2) 
     'request_id' => string '3' (length=1) 
     'coach_uin' => string '802877145' (length=9) 
     'date_intervention' => string '2015-06-01 00:00:00' (length=19) 
     'time_slot' => string 'AM' (length=2) 
    1 => 
    array (size=5) 
     'id' => string '12' (length=2) 
     'request_id' => string '3' (length=1) 
     'coach_uin' => string '802310154' (length=9) 
     'date_intervention' => string '2015-06-02 00:00:00' (length=19) 
     'time_slot' => string 'PM' (length=2) 
    2 => 
    array (size=5) 
     'id' => string '13' (length=2) 
     'request_id' => string '3' (length=1) 
     'coach_uin' => string '801777170' (length=9) 
     'date_intervention' => string '2015-06-03 00:00:00' (length=19) 
     'time_slot' => string 'AM' (length=2) 

陣列2：

array (size=3) 
    0 => 
    array (size=9) 
     'user_id' => string '5' (length=1) 
     'user_role' => string 'coach' (length=5) 
     'uin' => string '802877145' (length=9) 
     'manager_uin' => string '607518069' (length=9) 
     'phone' => string '8021111111' (length=10) 
     'ouc' => string 'BVG1C3' (length=6) 
     'email' => string 'brendan@XXXXXXXX.co.uk' (length=23) 
     'first_name' => string 'Brendan' (length=7) 
     'last_name' => string 'Kane' (length=4) 
    1 => 
    array (size=9) 
     'user_id' => string '4' (length=1) 
     'user_role' => string 'coach' (length=5) 
     'uin' => string '802310154' (length=9) 
     'manager_uin' => string '607518069' (length=9) 
     'phone' => string '802111111' (length=9) 
     'ouc' => string 'BVG1C3' (length=6) 
     'email' => string 'charlie@XXXXXXX.co.uk' (length=23) 
     'first_name' => string 'Charles' (length=7) 
     'last_name' => string 'McIntosh' (length=8) 
    2 => 
    array (size=9) 
     'user_id' => string '3' (length=1) 
     'user_role' => string 'engineer' (length=8) 
     'uin' => string '801777170' (length=9) 
     'manager_uin' => string '607518069' (length=9) 
     'phone' => string '801111111' (length=9) 
     'ouc' => string 'BVG1C3' (length=6) 
     'email' => string 'nat@XXXXXX.co.uk' (length=19) 
     'first_name' => string 'Nat' (length=3) 
     'last_name' => string 'Mcghie' (length=6) 

我想這個數據合併到單個數組，其中存在匹配Array1中的coach_uin和Array2中的uin。

我曾嘗試： $merged_data = array_merge($coach_assignment_data,$coach_user_info);

但它返回這樣的：

array (size=6) 
    0 => 
    array (size=5) 
     'id' => string '11' (length=2) 
     'request_id' => string '3' (length=1) 
     'coach_uin' => string '802877145' (length=9) 
     'date_intervention' => string '2015-06-01 00:00:00' (length=19) 
     'time_slot' => string 'AM' (length=2) 
    1 => 
    array (size=5) 
     'id' => string '12' (length=2) 
     'request_id' => string '3' (length=1) 
     'coach_uin' => string '802310154' (length=9) 
     'date_intervention' => string '2015-06-02 00:00:00' (length=19) 
     'time_slot' => string 'PM' (length=2) 
    2 => 
    array (size=5) 
     'id' => string '13' (length=2) 
     'request_id' => string '3' (length=1) 
     'coach_uin' => string '801777170' (length=9) 
     'date_intervention' => string '2015-06-03 00:00:00' (length=19) 
     'time_slot' => string 'AM' (length=2) 
    3 => 
    array (size=9) 
     'user_id' => string '5' (length=1) 
     'user_role' => string 'coach' (length=5) 
     'uin' => string '802877145' (length=9) 
     'manager_uin' => string '607518069' (length=9) 
     'phone' => string '8021111111' (length=10) 
     'ouc' => string 'BVG1C3' (length=6) 
     'email' => string 'brendan@XXXXXX.co.uk' (length=23) 
     'first_name' => string 'Brendan' (length=7) 
     'last_name' => string 'Kane' (length=4) 
    4 => 
    array (size=9) 
     'user_id' => string '4' (length=1) 
     'user_role' => string 'coach' (length=5) 
     'uin' => string '802310154' (length=9) 
     'manager_uin' => string '607518069' (length=9) 
     'phone' => string '802111111' (length=9) 
     'ouc' => string 'BVG1C3' (length=6) 
     'email' => string 'charlie@XXXXXX.co.uk' (length=23) 
     'first_name' => string 'Charles' (length=7) 
     'last_name' => string 'McIntosh' (length=8) 
    5 => 
    array (size=9) 
     'user_id' => string '3' (length=1) 
     'user_role' => string 'engineer' (length=8) 
     'uin' => string '801777170' (length=9) 
     'manager_uin' => string '607518069' (length=9) 
     'phone' => string '801111111' (length=9) 
     'ouc' => string 'BVG1C3' (length=6) 
     'email' => string 'nat@XXXXX.co.uk' (length=19) 
     'first_name' => string 'Nat' (length=3) 
     'last_name' => string 'Mcghie' (length=6) 

有合併基礎上uin更快的方法？

感謝

要完成你的要求，你將不得不合並的每個陣列的內陣列。一種解決這個問題的方法是嵌套的foreach循環，如下所示：

foreach($Array2 as $coach){ 
    foreach($Array1 as $assignment){ 
    if(strCmp($coach['uin'],$assignment['coach_uin']) === 0){ 
     $merged_data[] = array_merge($coach, $assignment); 
    } 
    } 
}
