$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),

$tem_moeny [] = $arr['moeny'];

$tem_moeny [] = $tArr['moeny'];

}

$tem_moeny[] = $tArr['moeny'];

$n_arr['moeny'] = $tem_moeny;

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);
