PHP Coding Specification (_php) tutorial

6 If and ELSE statements

The If-else statement should have the following format:

if (condition) {/* conditions to operate on */
statements;
}

if (condition) {/* The condition of the operation. */
statements;
} else {/* conditions for Operation */
statements;
}

if (condition) {/* conditions to operate on */
statements;
} else if (condition) {/* conditions to operate on */
statements;
} else{/* conditions of operation */
statements;
}

NOTE: The If statement is always enclosed in "{" and "}", avoiding the following formatting that is prone to error:

if (condition)//Avoid this notation, he ignores "{}"
Statement

Note Formats can also be written in this way as follows

if (condition) {
/* Conditions for Operation */
statements;
} else {
/* Conditions for Operation */
statements;
}
