Answer 1

您需要像此参考链接一样使用array_merge

$result = array_merge($array1, $array2);

Answer 2

To get matched values from array , use array_intersect();

Example:

 <?php 
 $ar1 = array  ('1','2','5');
 $ar2 = array  ('1','2','7');
 $ar3 = array  ('1','2','5');
 $result = array_intersect($ar1,$ar2,$ar3); 
 print_r($result);
 ?>

Answer 3

Tough I am not clear, but assuming this is what you want to do.

$main = $var[0];
unset($var[0]);
foreach ($var as $key => $vals) {
  foreach ($vals as $innerkey => $val) {
    $var[$key][$main[$innerkey]] = $val;
    unset($var[$key][$innerkey]);
  }
}

Output:

Array
(
    [1] => Array
        (
            [COURSE] => B.Ed. DEGREE EXAMINATION DECEMBER-2012
            [STUDREGNO] => 108023004
            [STUDNAME] => RAMAKRISHNA REEMALI
            [FNAME] => 
            [SUBNAME1] => Personality Development
        )

    [2] => Array
        (
            [COURSE] => B.Ed. DEGREE EXAMINATION DECEMBER-2012
            [STUDREGNO] => 108027067
            [STUDNAME] => RADHIKA NARABOINA
            [FNAME] => 
            [SUBNAME1] => English
        )

)

Edited

Take a look at the variable names. may be you need to replace $var by $arr
