php - 构建php变量的名称

Question

$service3_step1_person = ‘999’;    
echo $service3_step1_person;    //999

进而...

$service = "service3";    
echo "$".$service."_step1_person;  //$service3_step1_person

它没有给我999，只是给我一串$service3_step1_person.

如何使字符串成为新的变量名？谢谢！

变量变量：

$service3_step1_person = ‘999’;
$service = "service3";
$variableName = "{$service}_step1_person";  
echo $$variableName; // 999

试试这个：

 $service = "service3";
 $temp = "_step1_person";
 echo ${$service.$temp};
