While it's understandable that the PHP developers don't consider this a bug, or don't consider it a bug worth their time, jsimlo was right to point out that mixing alternative if syntaxes might lead to unexpected results. Instead of concluding that the else statement was intended to match the if($b) statement (and erroring out), the parser could match the else statement to the if($a) statement, which shares its syntax. In other words, one would expect that this would work: Let me show you by example two scenarios. We also cover the alternative syntax for if and switch statements (often used in applications like WordPress) and the ternary operator for simple if/else statements.

PHP IF ELSE STATEMENT SHORTHAND HOW TO

So, this is why PHP shorthand exists What is a PHP shorthand If statement It is a short version of the full IF statement that you can directly echo out. In this tutorial we learn how to control the flow of our PHP application through conditional logic with if, else if, else and switch statements.

The following is illegal (as it should be):īut since the two alternative if syntaxes are not interchangeable, it's reasonable to expect that the parser wouldn't try matching else statements using one style to if statement using the alternative style. But to output the data in the DOM using a straight php if statement can be messy at best. The parser doesn't handle mixing alternative if syntaxes as reasonably as possible. Making statements based on opinion back them up with references or personal experience. Of elseif in a single word becomes necessary. Will only be considered exactly the same when using curly bracketsĪs in the above example. Preceding if expression and any preceding The one liner if is also known as the ternary operator if you want to look it up in the PHP documentation.

The elseif statement is only executed if the The shorthand if/else or ternary operator is a concise way to write if/else statements in PHP, as it allows you to write an if/else statement on a single line. //Make the variable today hold the value Thursday today Thursday //Test if the variable today is Friday, //if it is then we can go to the pub for lunch.

0 will be returned when both operands are equals, 1 when the left operand is larger, and -1 when the right operand is larger. Is that both would result in exactly the same behavior. It will always return one of three values: 0, -1 or 1. Is slightly different (the same behavior as C) but the bottom line In PHP, it's possible to writeĮlse if (in two words) and the behavior would be identical

There may be several elseifs within the sameĮlseif expression (if any) that evaluates to It has also been called the short if statement and the single line if statement.
