You can use:
您可以使用:
substr ($getstring->string, -4)
Because of (-) it will start form the end of the string and it will take the next 4 characters.
由于 (-) 它将从字符串的末尾开始,并将占用接下来的 4 个字符。
Take care that first() it will return an object and not the string you want.
注意 first() 它将返回一个对象而不是您想要的字符串。

string substr ( string $string , int $start [, int $length ] )
string substr ( string $string , int $start [, int $length ] )
$dynamicstring = "12-07-2017"; $newstring = substr($dynamicstring, -4);
$dynamicstring = "12-07-2017"; $newstring = substr($dynamicstring, -4);
