【PHP-switch条件类型、排序】
例1：
$a=array(0,707,708,'ssid');
$b=array();
foreach ($a as $key => $value) {
switch ((string)$value) {
case 'ssid':
$c='ssid';
break;
case 0:
$c='sindex';
break;
case 707:
$c='login';
break;
case 708:
$c='register';
break;
}
if(!isset($b[$c])){
$b[$c]=array();
}
}
print_r($b);
结果：array('sinde'=>array(),'login'=>array(),'register'=>array(),'ssid'=>array())
例2：
$a=array(0,707,708,'ssid');
$b=array();
foreach ($a as $key => $value) {
switch ($value) {
case 'ssid':
$c='ssid';
break;
case 0:
$c='sindex';
break;
case 707:
$c='login';
break;
case 708:
$c='register';
break;
}
if(!isset($b[$c])){
$b[$c]=array();
}
}
print_r($b);
结果：array('sinde'=>array(),'login'=>array(),'register'=>array())
例3：
$a=array(0,707,708,'ssid');
$b=array();
foreach ($a as $key => $value) {
switch ((string)$value) {
case 0:
$c='sindex';
break;
case 707:
$c='login';
break;
case 708:

case 'ssid':

break;
}
if(!isset($b[$c])){
$b[$c]=array();

print_r($b);
结果：array('sinde'=>array(),'login'=>array(),'register'=>array())
PHP中switch，十点睡觉。有时间分析源码再看细节
