本文介紹了PHP應用：php數(shù)組實現(xiàn)根據(jù)某個鍵值將相同鍵值合并生成新二維數(shù)組的方法，希望對您有用。如果有疑問，可以聯(lián)系我們。
PHP應用本文實例講述了php數(shù)組實現(xiàn)根據(jù)某個鍵值將相同鍵值合并生成新二維數(shù)組的方法.分享給大家供大家參考,具體如下：
PHP應用源數(shù)據(jù)：
PHP應用
$infos = array(
array(
'a' => 36,
'b' => 'xa',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 3,
'b' => 'vd',
'c' => '2015-08-20 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 6,
'b' => 'wwe',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 36,
'b' => 'se',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 6,
'b' => 'aw',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 36,
'b' => 'bv',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 12,
'b' => 'xx',
'c' => '2015-08-27 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
)
);
PHP應用處理要求：將數(shù)組中a相同的二維數(shù)組合并到一個數(shù)組中,生成一個新的數(shù)組
PHP應用代碼：
PHP應用
<?php
$result= array();
foreach ($infos as $key => $info) {
$result[$info['a']][] = $info;
}
print_r($result);
PHP應用輸出：
