How do I make PHP output all error information programatically?

Question

I can't change the php.ini for some reason,

how can I do it in code level?

If you have access to your php.ini, I would first try to find out why you can't change any values in there. — Pekka

note that ini_set won't help with parse errors. .htaccess is another option where available — Your Common Sense

Try

ini_set — Sets the value of a configuration option

Example from Manual:

if (!ini_get('display_errors')) {
    ini_set('display_errors', 1);
}

but keep in mind your hosting service might have disabled programmatic setting of ini settings.

Also keep in mind that you have to have error_reporting enabled:

error_reporting — Sets which PHP errors are reported

Example from Manual:

// Report all PHP errors
error_reporting(-1);

Isn't error_reporting(-1); enough ? Do I also set display_errors to on?

@user198729 error_reporting just sets what is reported, not if it is displayed.

Use ini_set (https://www.php.net/manual/en/function.ini-set.php)

Specifically,

ini_set('display_errors', 'E_ALL');

should work

@Col. Shrapnel What's so ridiculous about it?

Runtime configuration of error reporting can be finetuned with a number of functions, listed here: http://www.php.net/manual/en/errorfunc.configuration.php

But most directly related to your question, use error_reporting(E_ALL), and display_errors(1)

error_reporting(-1); //Passing in the value -1 will show every possible error, even when new levels and constants are added in future PHP versions
ini_set('display_errors', 'On');

Doc available there:

Another way (if your server supports it) is with an .htaccess file:

php_flag display_errors on
php_value error_reporting -1

(tip) Passing in the value -1 will show every possible error, even when new levels and constants are added in future PHP versions.

AlexV Over a year ago

I guess because it's bytewise and -1 equals to all flags raised?

because Rasmus said so twitter.com/rasmus/status/7448448829 ;) well, actually, it's also at the bottom of the manual page for error_reporting.

In PHP:

error_reporting(E_ALL | E_STRICT);

From an .htaccess file:

php_value error_reporting 6143

6143 is the integer value of E_ALL, since apache won't understand "E_ALL"
