$test1 = Array(
0 => Array(
'id' => 9478137,
'create_time' => 1394760724
),
1 => Array(
'id' => 9478138,
'create_time' => 1394760725

2 => Array(
'id' => 9478138,
'create_time' => 1394760725

$test2 = array(
0 => array(
'id' => 9478137,
'message' => 'love you'
),
1 => array(
'id' => 9478138,
'message' => 'miss you'
)
);

function _mergerArray($array1, $array2, $field1, $field2 = '') {
$ret = array();

//使用数组下标的办法
foreach ($array2 as $key => $value) {
$array3[$value[$field1]] = $value;
}
foreach ($array1 as $key => $value) {
$ret[] = array_merge($array3[$value[$field1]], $value);
}
return $ret;
}
$ret = _mergerArray($test1, $test2, 'id', 'id');
print_r($ret);exit;
