我有一个字符串列表var_dump($key)
:
string(6) "samuel"
string(4) "john"
string(4) "alan"
string(5) "frank"
string(3) "bob"
它们是来自多维数组的循环的结果:
foreach ($array as $key => $item) {
if(is_array($item)){
if (stripos($key, $keySearch) !== false){
var_dump($key);
}
}
}
是否可以对此字符串列表进行排序?
我试过了:
foreach ($array as $key => $item) {
if(is_array($item)){
if (stripos($key, $keySearch) !== false){
asort($key);
var_dump($key);
}
}
}
以及
foreach ($array as $key => $item) {
if(is_array($item)){
if (stripos($key, $keySearch) !== false){
array_multisort($key);
var_dump($key);
}
}
}
我的排序不起作用。问题是我无法对array
进行排序,因为它是一个复杂的多维数组。所以我不知何故只想对结果进行排序。但我不知道该怎么做。
我希望var_dump($key)
的结果是:
string(4) "alan"
string(3) "bob"
string(5) "frank"
string(4) "john"
string(6) "samuel"

PHP - 为数组排序函数
sort() - sort arrays in ascending order
rsort() - sort arrays in descending order
asort() - sort associative arrays in ascending order, according to the value
ksort() - sort associative arrays in ascending order, according to the key
arsort() - sort associative arrays in descending order, according to the value
krsort() - sort associative arrays in descending order, according to the key
