Summary: "array to string conversion" notice should contain
more information

This is not just difficult, this is to the most part impossible. In this
particular case where the array->string conversion happens to be the result of
a concatenation of variables, sure, one could in theory (with a sufficient
amount of special casing) give you a variable name.
But usually this is not the case. Instead the error happens as part of some
other operation or using the result of some other operation. This particular
notice for example often occurs inside functions like array_diff. There is no
responsible "variable name" in such cases.

Ok. The correct status would be "won't fix", however.
This is a more general issue, actually. It applies to most error messages. Line
number is often not enough, and having to split a line of code into multiple
lines every time you have to debug an error (and then, get them back to one
line
so the code doesn't become unreadable) is definitely not viable.

That's actually surprisingly difficult to do given how bison (the parser
generator) works. You can do it quite easily in userspace though. Just break up
the line you are having trouble with over multiple lines and the line number
will
tell you which variable it is.

Description:
------------
The "Array to string conversion" notice message should at the very least
include
the name of the array variable that is being converted to string.
A line of code may contain a lot of variables, so figuring out which one is the
unexpected array can be a pain in the ass.
Even the backtrace won't contain enough information since it only gives the
line
but not the position within the line.
Test script:
---------------
$string1="foo";
$string2="bar";
$string3=array("Whoops, this is an array");
$string4="bla bla";
echo $string1.$string2.$string3.$string4.
Expected result:
----------------
PHP NOTICE at /path/to/file.php (6): Array to string conversion for variable
'string3'
Actual result:
--------------
PHP NOTICE at /path/to/file.php (6): Array to string conversion
------------------------------------------------------------------------
