PHP - If/else, for, foreach, while - without curly braces?

Question

Something that really would like to know but never found out are shortcuts in PHP.

I am currently coding a function with a foreach loop with just a sing

Answer 1

The answer is easy. This is the same in C/C++.

if, if/else, if/else if/ else and loops => If the next statement is one single line, you can omit the curly braces.

Ex:

for($i= 0; $i<=100; $i++)
{
    if($i % 7 == 0)
    {   
        echo $i . "
";
    }

}

It can also be written in this way:

for($i= 0; $i<=100; $i++) if($i % 7 == 0) echo $i . "
";
