Question

今天我尝试将PHP版本从5.6更改为7.0。而且大部分代码都能正常工作，但是我遇到了数组问题。

CODE：

$settings = Core_Settings::find_by_sql("SELECT * FROM core_settings");
foreach($settings as $setting) 
{
    $array =  (array) $setting;
    $$array['name'] = $array['data'];
}

$settings = 
Array ( [0] => Core_Settings Object ( [name] => WWW [data] => http://10.20.31.230/ ) [1] => Core_Settings Object ( [name] => SITE_NAME [data] => Istracom - VPN Access Manager ) [2] => Core_Settings Object ( [name] => SITE_DESC [data] => UPRAVLJAČKI SUSTAV ZA VPN VEZE! ) [3] => Core_Settings Object ( [name] => SITE_KEYW [data] => vpn ) [4] => Core_Settings Object ( [name] => ADMINDIR [data] => admin/ ) [5] => Core_Settings Object ( [name] => SITE_EMAIL [data] => Istracom d.o.o. ) [6] => Core_Settings Object ( [name] => DATABASE_SALT [data] => 293847 ) [7] => Core_Settings Object ( [name] => PAGINATION_PER_PAGE [data] => 20 ) [8] => Core_Settings Object ( [name] => TIMEZONE [data] => Europe/Sarajevo ) [9] => Core_Settings Object ( [name] => ADMIN_LEVEL [data] => 293847 ) [10] => Core_Settings Object ( [name] => THEME_NAME [data] => istracom ) [11] => Core_Settings Object ( [name] => BRUTEFORCE_LIMIT [data] => 5 ) [12] => Core_Settings Object ( [name] => BRUTEFORCE_TIMEOUT [data] => 0 ) [13] => Core_Settings Object ( [name] => LOGO [data] => https://vpn.jadranka.hr/vpn/assets/img/jadlogo.png ) [14] => Core_Settings Object ( [name] => ADMIN_EMAIL [data] => itpodrska@jadranka.hr ) [15] => Core_Settings Object ( [name] => VERIFY_EMAIL [data] => YES ) [16] => Core_Settings Object ( [name] => PRAVILA [data] => https://vpn.jadranka.hr/vpn/downloads/VPN%20-%20korisni%C4%8Dka%20pravila.pdf ) [17] => Core_Settings Object ( [name] => PRAVILAUSERA [data] => VPN korisničko ime ne možete naknadno promijeniti. Korisničko ime VPN-a se koristi za ostvarivanje VPN veza.

数组到字符串转换

未定义的变量：XXX

Answer 1

带数组的双元符号会产生问题，因为$ array变量本身就是一个数组。因此，分别解析完整的$ array [＆＃39; name＆＃39;]。使用此解决方案：

foreach($settings as $setting)
{  
    $array =  (array) $setting;
    ${$array['name']} = $array['data'];
}

OR

foreach($settings as $setting)
{  
    $array =  (array) $setting;
    $name = $array['name'];    
    $$name = $array['data'];
}
