php复杂数组如何重组
$arr = array(
array('fid'=85,'fup'=23,'type'='sub'),
array('fid'=66,'fup'=3,'type'='sub'),
array('fid'=188,'fup'=2,'type'='sub'),
array('fid'=57,'fup'=41,'type'='gro'),
array('fid'=35,'fup'=98,'type'='wc'),
array('fid'=54,'fup'=22,'type'='bfo'),
);
$result = array();
foreach($arr as $k=$v){
if($v['type']=='sub'){
$result[$v['fid']] = $v;
}
}
print_r($result);
这样既可。
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);
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 数组分割重组
?php
$arr = array(
array("title"="w15","url"="l2","url2"="width","value"="3.2"),
array("title"="w15","url"="l3","url2"="width","value"="3.1"),
array("title"="w15","url"="l4","url2"="width","value"="3.0"),
array("title"="w15","url"="l5","url2"="width","value"="3.1"),
array("title"="w15","url"="l6","url2"="width","value"="3.4"),
array("title"="w16","url"="l8","url2"="width","value"="3.8"),
array("title"="w16","url"="l9","url2"="width","value"="3.9")
);
$new_arr = array();
foreach($arr as $item) {
$k = $item['title'];
if(!isset($new_arr[$k])) {
$new_arr[$k] = array(
'title' = $k,
'url' = array($item['url']),
'url2' = array($item['url']),
'value' = array($item['value'])
);
} else {
$new_arr[$k]['url'][] = $item['url'];
$new_arr[$k]['url2'][] = $item['url2'];
$new_arr[$k]['value'][] = $item['value'];
}
}
//print_r($new_arr); // 如果用 title 做 key, 到这儿就可以了
$new_arr = array_values($new_arr);
print_r($new_arr);
