if (expr)
   statement

The general format of if construct is like shown below:

if (expr1) {
   //  statement if expr 1 true
} else if (expr2) {
   // statement if expr 2 true
} else {
   // statement if expr 1 and 2 false
}

You may find useful documentation about if construct, else and else if in php.net.

But how if you only need two condition to produce a word or digit, and then save it into a variable or just echo it? You may write it like shown below:

if ($status = '0')
   echo 'Draft';
else
   echo 'Published';

In code example above, you need to write four lines. Compare with code shown below:

echo $status == '0' ? 'Draft' : 'Published';

The syntax is show below

echo expr ? 'value if true' : 'value if false';

You may change echo with variable assignment such as:

$var = expr ? 'value if true' : 'value if false';

Easy right? It cuts down four lines into one line only.
