Depending on the density of cases of multiple instructions per line of code, and based on specific threshods, Highlight counts penalty points for the scanned file.

The following patterns are used to detect them:
– more than one “;”
– “{” … statement … “;”
– statement … “; }”
– “;” and one of the following keywords: while, for, foreach, if else, switch, try, catch, finally, do…
– more than one keyword listed above, except for “else if” [/vc_column_text][vc_separator color=”grey” align=”align_center”][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]

Why you should care

Having multiple instructions in one line of code remarkably decreases readability of your software. In addition to making source code harder to understand, developers may miss some important instructions – because they’re in the middle of others – that could impact the software execution (e.g. if(today == “Monday”) { echo “Have a good week”; formatUserDrive(); echo “and a great week-end too!”; }

CAST recommendations

Although in some cases there may be a good reason to have more than one instruction per line (e.g. very simple code like “if(found) { break; }”), it is generally agreed by the developer community that each instruction should have its own code line.[/vc_column_text][vc_separator color=”grey” align=”align_center” style=”” border_width=”” el_width=””][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]
