Several questions on “what is the shortest code for this?“:

1. Without {}

   if($match->name == "Marry") {
       $match = true;
   }
   

2. Without {}

   }
   

3. How to ask if $match = true?

4. How to ask if array() has any value?

5. How to ask if $variable has numeric value (0-9)?

6. How to ask if $variable's first symbol isn't a letter or number?

7. How to ask if $match = false?

Answer 1

1)

$match = ($match->name == "Marry") ? true : $match;

2)

$match = ($match->name == "Marry");

3)

if ( $match === true ) {}

4)

$array = array();
if ( !empty( $array ) ) {}

5)

if ( is_numeric( $variable ) ) {}

6)

if ( ctype_alnum($variable[0]) ) ) {}
