$laArray = array(
0 = array("id"=11,"name"="happy","age"="20","moeny"=100),
1 = array("id"=29,"name"="lucy","age"="20","moeny"=100),
2 = array("id"=34,"name"="happy","age"="20","moeny"=235),
3 = array("id"=42,"name"="happy","age"="15","moeny"=100),
4 = array("id"=51,"name"="happy","age"="20","moeny"=600),

PHP 一个数组中 根据某个相同的值 将不同的值重组一个新数组
例子：
复制代码 代码如下:
?php
$array1 = array("color" = "red", 2, 4);
$array2 = array("a", "b", "color" = "green", "shape" = "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?
上例将输出：
复制代码 代码如下:
Array
(
[color] = green
[0] = 2
[1] = 4
[2] = a
[3] = b
[shape] = trapezoid
[4] = 4
)
如何将 php 二维数组重组
?php
$a=array(
0 = array(
"yw" ="85",
"sx" ="97",
"yy" ="100"
),
1= array(
"yw"= "85.5",
"sx" = "96",
"yy"= "96"
),
2= array(
"yw" = "84.5",
"sx" = "90",
"yy" = "98",
)
);
$f=array();
foreach($a as $b=$c){
foreach($c as $d=$e){
$f[$d][]=$e;
}
}
echo 'pre/';
print_r($f);

php数组重组
是固定的么？
?php
$a = array('0' = array('id' = 151,'name'='leo'),
'1' = array('id' = 120,'name'='john'),
'2' = array('id' = 153,'name'='hello'),
'3' = array('id' = 118,'name'='word'),
);
foreach($a as $k = $v){
if($v['id']==151 || $v['id']==120){
$b['0'][] = $a[$k];
}else{
$b['1'][] = $a[$k];
}
}
var_dump($b);
