本文介绍了如何合并两个数组没有在PHP中的重复值?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有两个数组:
1.这里的每个对象是从数据库retrived一行。
阵列
1 =>
对象(stdClass的)[41]
公众'ID'=>串1(长度= 1)
公众标识码'=>字符串'25'(长度= 2)
公众SECTION_ID'=>串'2'(长度= 1)
公众student_id数据'=>串1(长度= 1)
公众日期=>字符串'2011-11-26'(长度= 10)
公众出席'=>字符串'present'(长度= 7)
2 =>
对象(stdClass的)[41]
公众'ID'=>串1(长度= 1)
公众标识码'=>字符串'25'(长度= 2)
公众SECTION_ID'=>串'2'(长度= 1)
公众student_id数据'=>字符串'3'(长度= 1)
公众日期=>字符串'2011-11-26'(长度= 10)
公众出席'=>字符串'present'(长度= 7)
2。另一个数组是从我的形式,这看起来是这样的。
阵列
0 =>
排列
标识码'=>字符串'25'(长度= 2)
SECTION_ID'=>串'2'(长度= 1)
student_id数据'=> INT 1
'日期'=>字符串'2011-11-26 00:00:00'(长度= 19)
'出勤'=>字符串'present'(长度= 7)
1 =>
排列
标识码'=>字符串'25'(长度= 2)
SECTION_ID'=>串'2'(长度= 1)
student_id数据'=> INT 2
'日期'=>字符串'2011-11-26 00:00:00'(长度= 19)
'出勤'=>字符串'present'(长度= 7)
下面是我想要做的是:结果
- 比较这两个,并检查重点student_id数据和日期已经在数据库或没有结果。
- 从第二阵列中,从表单数据,删除重复的和插入的数据结果。
最后的结果应该是:结果
阵列
0 =>
排列
标识码'=>字符串'25'(长度= 2)
SECTION_ID'=>串'2'(长度= 1)
student_id数据'=> INT 2
'日期'=>字符串'2011-11-26 00:00:00'(长度= 19)
'出勤'=>字符串'present'(长度= 7)
解决方案
尝试:
$ C = [array_merge] [1]($ A,$ B);后续代码var_dump([array_unique] [1]($ C));
希望它能帮助
I have two arrays: 1. each object here is a row retrived from database.
array
1 =>
object(stdClass)[41]
public 'id' => string '1' (length=1)
public 'class_id' => string '25' (length=2)
public 'section_id' => string '2' (length=1)
public 'student_id' => string '1' (length=1)
public 'date' => string '2011-11-27' (length=10)
public 'attendance' => string 'present' (length=7)
2 =>
object(stdClass)[41]
public 'id' => string '1' (length=1)
public 'class_id' => string '25' (length=2)
public 'section_id' => string '2' (length=1)
public 'student_id' => string '3' (length=1)
public 'date' => string '2011-11-27' (length=10)
public 'attendance' => string 'present' (length=7)
2. Another array is from my form and this looks like this.
array
0 =>
array
'class_id' => string '25' (length=2)
'section_id' => string '2' (length=1)
'student_id' => int 1
'date' => string '2011-11-27 00:00:00' (length=19)
'attendance' => string 'present' (length=7)
1 =>
array
'class_id' => string '25' (length=2)
'section_id' => string '2' (length=1)
'student_id' => int 2
'date' => string '2011-11-27 00:00:00' (length=19)
'attendance' => string 'present' (length=7)
Here what I want to do is:
- compare these two and check if key student_id and date are already on database or not.
- and from second array which is from form data, remove duplicate and insert into data.
The final result should be:
array
0 =>
array
'class_id' => string '25' (length=2)
'section_id' => string '2' (length=1)
'student_id' => int 2
'date' => string '2011-11-27 00:00:00' (length=19)
'attendance' => string 'present' (length=7)
解决方案
Try:
$c = [array_merge][1]($a,$b); var_dump([array_unique][1]($c));
