下列程序的运行结果是（）。class student{function _construct(){echo "I am a student .<br>";}function teacher(){echo "I am a teacher";}}$per=new student();
A: I am a studentI am a teacher

- 已知s1="I "am a student.",s2='I \'am a student',则print(s1,s2)的输出结果为( ) A: I 'am a student. I 'am a student B: I "am a student. I 'am a student C: I "am a student. I \'am a student D: 程序报错
- 设串S1='I AM'，S2=' A STUDENT'，则ConcatStr(S1,S2)=( )。 A: 'I AM' B: 'A STUDENT' C: 'I AM A STUDENT' D: 'IAMASTUDENT'
- “I am a student”=“am”的值是
