Errores en PHP 7

PHP 7 cambia la mayoría de los errores notificados por PHP. En lugar de notificar errores a través del mecanismo de notificación de errores tradicional de PHP 5, la mayoría de los errores ahora son notificados lanzando excepciones Error.

Al igual que las excepciones normales, las excepciones Error se propagarán hasta alcanzar el primer bloque catch coincidente. Si no hay bloques coincidentes, será invocado cualquier manejador de excepciones predeterminado instalado con set_exception_handler(), y si no hubiera ningún manejador de excepciones predeterminado, la excepción será convertida en un error fatal y será manejada como un error tradicional.

Debido a que la jerarquía de Error no hereda de Exception, el código que emplee bloques catch (Exception $e) { ... } para manejar excepciones no capturadas en PHP 5 encontrará que estos Errores no son capturados por dichos bloques. Se requiere, por tanto, un bloque catch (Error $e) { ... } o un manejador set_exception_handler().

You can catch both exceptions and errors by catching(Throwable)

Throwable does not work on PHP 5.x.

To catch both exceptions and errors in PHP 5.x and 7, add a catch block for Exception AFTER catching Throwable first.
Once PHP 5.x support is no longer needed, the block catching Exception can be removed.

try
{
   // Code that may throw an Exception or Error.
}
catch (Throwable $t)
{
   // Executed only in PHP 7, will not match in PHP 5
}
catch (Exception $e)
{
   // Executed only in PHP 5, will not be reached in PHP 7
}

An excellent blog post on the difference between exceptions, throwables and how PHP 7 handles these can be found here: https://trowski.com/2015/06/24/throwable-exceptions-and-errors-in-php7/

the node said that i can get the error by catch{Error $e}block or a set_exception_handler() handler is required.
here is my code:
try{
    array_key_exists('key',null);
}
catch(\Throwable | \Error | \Exception $e){
    echo 'hello error';
}

I deliberately wrote a warning code and the output is "Warning: array_key_exists() expects parameter 2 to be array, null given in"

the result i want is "hello error" but i didn't get it.

and in the other code :
set_error_handler('show_error');

try{
    array_key_exists('key',null);
}
catch(\Throwable | \Error | \Exception $e){
    echo 'hello error';
}

function show_error(\Error $e){
    echo "show_error:"
    echo $e->getMessage();
}

the output is "hello error".

i don't know how the error can be caught  by the catch block.

What should I do to let the program to react to warnings? I've already tried to write try/catch construction, but it doesn't working.

Maybe you want to suppress warnings in errlog? If so, then just prepend function name with @ sign.
