Edit Question
Title
Body
The following PHP code will output 3 . function main() { if (1) { $i = 3; } echo $i; } main(); But the following C code will raise a compile error. void main() { if (1) { int i = 3; } printf("%d", i); } So variables in PHP are not strictly block-scoped? In PHP, variables defined in inner block can be used in outer block?
