So this is my explanation. (Before you read the answer try to read code below on how things are being executed - especially notice how the last print() statement are being printed normally.) First of all in PHP, a print() returns a value 1. Keeping that in mind, now let us see the first print statement. 1) print("hey") && print(" ") && print("you"); // you11 this is being treated something like print(("hey" && print(" " && print("you"))); by the compiler during the execution. And we know parenthesis has the highest precedence/priority so that the first part that is being executed is print("you") giving "you", then this print(" " && print("you")) is being executed(we know that print() always give 1) so this statement is simply print(1)[(" " && print("you")) equals to 1] and therefore we have something like "you1" as of now. Similarly this print(("hey" && print(" " && print("you"))); is simply print(1) and hence the final output is "you11".
