there is a confusion among a few about the following example,

if(condition)
echo “i am first line”;
echo “i am not executed”;

the above code doesn’t mean that the second line will never be executed. One should interpret this example with context to my explanation of IF statement before this example. I have not posted exact code but it’s kinda pseudo code to explain that if you are not making block of code using braces for your IF statement then the first line after IF will be executed as the part of IF statement and the lines following will not be executed as the part of IF though the control will go to them.

therefore to execute more than one line as part of IF statement you should use braces to make block of code.
