Block Syntax
Most programming languages use curly brackets { } to group statements, forming a block. However, this has the inherent problem that it is often a fight between style fanatics to either save space and write it on the same line as the condition, or style fanatics to write it on a seperate line, aligning the opening and closing brackets. There are better alternatives for curly brackets (most language designers feel that curly brackets where a terribly idea in the first place). Bellow are some alternatives.
C syntax with starting bracket on same line as the conditional statement:
if (x==3) { echo "three!"; return; }
C syntax with the starting bracket aligned with the closing bracket:
if (x==3) { echo "three!"; return; }
C syntax, with Whitesmiths style C indentation, arguing that { and } are not part of the if statement:
if (x==3) { echo "three!"; return; }
Pascal Syntax: begin and end instead of { }:
if (x=3) then begin echo "three!"; return end;
Shell syntax: as Pascal, but with if/then/fi instead of if/begin/end:
if [ $x -eq 3 ] then echo "three!"; return 0; fi
Shell syntax: with if/then on the same line:
if [ $x -eq 3 ]; then echo "three!"; return 0; fi
PHP (deprecated): using endif (or fi) as end statement, if automatically implies begin of a block:
if (x===3) : echo "three!"; return; endif;
Python syntax: indentation implies nesting, no need for end or } syntax:
if (x==3): echo "three!" return
