		if(
			!bBoolean[iClient]
#if defined MY_CHECK_BOTS
			|| IsFakeClient( iClient )
#endif
		)
			MyFunction( iClient );

error 057: unfinished expression before compiler directive

A bug?

[_AeonOne_]

Seems intended.
Just do this:

PHP Code:

#if defined MY_CHECK_BOTS
        if(!bBoolean[iClient] || IsFakeClient( iClient ))
#else
        if(!bBoolean[iClient])
#endif

"Compiler directives may only occur between statements, not inside a statement. This error typically occurs when an expression statement is split over multiple lines and a compiler directive appears between the start and the end of the expression. This is not supported."
