Mostrar todos los errores y advertencias
ACTUALIZAR 2:
Ahora he eliminado lo siguiente de la .archivo php:
<?php error_reporting( E_ALL ); ?>
He establecido display_erros en php.ini según se indica:
Display_errors = On
El reporte de errores se establece como sigue en php.ini
Error_reporting = E_ALL | E_STRICT
Después de reiniciar apache, todavía no recibo errores/advertencias.
ACTUALIZAR 1:
He cambiado error_reporting en php.ini de:
Error_reporting = E_ALL & ~E_DEPRECATED
A
Error_reporting = E_ALL | E_STRICT
Después de lo cual reinicié apache, por ejemplo,
/etc/init.d / apache2 restart
Pero la página todavía no mostrará errores/advertencias de ningún tipo.
PREGUNTA ORIGINAL:
El siguiente script está generando una advertencia porque el er err está dentro de la instrucción if. Por qué es esta advertencia no se muestra en la página php en un navegador web? Tengo que mirar los registros de Apache para ver la advertencia. Además, si delibarately cambio el " insertar en "a" eliminar en", no muestra un error en la página de php. ¿Por qué los errores no se muestran en la página php actual?

Los errores de visualización se pueden desactivar en el archivo php.ini o en su archivo de configuración de Apache.
Puede activarlo en el script:
error_reporting(E_ALL);
ini_set('display_errors', 1);
Debería ver los mismos mensajes en el registro de errores de PHP.

Directamente desde php.archivo ini:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; This directive informs PHP of which errors, warnings and notices you would like
; it to take action for. The recommended way of setting values for this
; directive is through the use of the error level constants and bitwise
; operators. The error level constants are below here for convenience as well as
; some common settings and their meanings.
; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
; those related to E_NOTICE and E_STRICT, which together cover best practices and
; recommended coding standards in PHP. For performance reasons, this is the
; recommend error reporting setting. Your production server shouldn't be wasting
; resources complaining about best practices and coding standards. That's what
; development servers and development settings are for.
; Note: The php.ini-development file has this setting as E_ALL. This
; means it pretty much reports everything which is exactly what you want during
; development and early testing.
;
; Error Level Constants:
; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
; E_ERROR - fatal run-time errors
; E_RECOVERABLE_ERROR - almost fatal run-time errors
; E_WARNING - run-time warnings (non-fatal errors)
; E_PARSE - compile-time parse errors
; E_NOTICE - run-time notices (these are warnings which often result
; from a bug in your code, but it's possible that it was
; intentional (e.g., using an uninitialized variable and
; relying on the fact it is automatically initialized to an
; empty string)
; E_STRICT - run-time notices, enable to have PHP suggest changes
; to your code which will ensure the best interoperability
; and forward compatibility of your code
; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
; initial startup
; E_COMPILE_ERROR - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR - user-generated error message
; E_USER_WARNING - user-generated warning message
; E_USER_NOTICE - user-generated notice message
; E_DEPRECATED - warn about code that will not work in future versions
; of PHP
; E_USER_DEPRECATED - user-generated deprecation warnings
;
; Common Values:
; E_ALL (Show all errors, warnings and notices including coding standards.)
; E_ALL & ~E_NOTICE (Show all errors, except for notices)
; E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.)
; E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors)
; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
; Development Value: E_ALL
; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
; http://php.net/error-reporting
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
Para el desarrollo puro voy por:
error_reporting = E_ALL ^ E_NOTICE ^ E_WARNING
También no olvides poner display_errors en
display_errors = On
Después de eso reinicie su servidor para apache en Ubuntu:
sudo /etc/init.d/apache2 restart

Pude obtener todos los errores a través del siguiente código: -
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);

Los errores de Php se pueden mostrar como cualquiera de los siguientes métodos:
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
Para más detalles:

Pon estos en php.ini
;display_startup_errors = On
display_startup_errors=off
display_errors =on
html_errors= on
Desde su página php use un filtro adecuado para reportar errores.
error_reporting(E_ALL);
Los declarantes se pueden hacer de acuerdo con los requisitos.
E_ALL
E_ALL | E_STRICT

Puede ver la descripción detallada aquí.
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
// Report all PHP errors
error_reporting(-1);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
