String concatination

[blasto333]

echo 'a'.false ? 'b' : 'c';

 

Why does this echo b?

 

Thank you,

'a' is true. concatenating false to the string doesn't change that. what are you trying to do?

This is what PHP is doing:

echo 'a'.false ? 'b' : 'c';
//becomes
echo strval('a'.false) ? 'b' : 'c';
//becomes
if ( strval('a' . false) == true ) {
  echo 'b';
} else {
  echo 'c';
}

A simple way to understand this is;

 

echo $isTrue ? 'YES' : 'NO';

 

This is relatively the same as;

 

if($isTrue) {
echo 'YES';
} else {
echo 'NO';
}
