Como fazer para ignorar caracteres depois da virgula


Olá amigos!

Como eu faço para ignorar os caracteres depois da virgula?


$valor1 = 15;

$valor2 = 2;

$valor3 = $valor1/$valor2;

echo $valor3;

Resultado = 7.5

Mas eu gostaria que ele sempre arredondasse para menos


Resultado = 7

Use a função floor, ela arredonda para baixo, também tem a função ceil que arredonda para cima, e round que segue as regras de arredondamento.
