I had not implemented this feature back then because I'm not sure it makes sense to support it in the context of a templating system. I'm still not convinced that this is useful.

Fix strict mode in extension when building in ZTS mode
This removes a few misplaced TSRMLS_CCs causing if() expressions to always evaluate to true. This caused twig_template_get_attributes to always behave as if strict mode were disabled.

Fix crash in twig_template_get_attributes when input is not an array or object
This fixes a crash when the input of twig_template_get_attributes() is not an array or object, and strict mode is enabled.

Could you maybe place the exception tests in a different method?
---------------------------------------------------------------------------

This method already expects many of its inputs to cause an exception to be thrown (it tests getAttribute() in strict mode, and in many cases the attribute isn't defined). I don't see a real benefit from moving these tests in a separate method in this case.

String interpolation syntax
This adds support for string interpolation:
```
{{ "foo #{ any expression here } bar" }}
```
I find string interpolation to be often more readable than concatenation, and doesn't have the precedence ambiguity of the concatenation operator:
```
Interpolation:
{{ "foo #{bar} baz" }}
{{ "foo #{1+2} baz" }}
{{ "foo #{1+2} baz"|escape }}
Concatenation:
{{ "foo "~bar~" baz" }}
{{ "foo "~(1+2)~" baz" }} extra parentheses
{{ ("foo "~(1+2)~" baz")|escape }} more extra parentheses
```

Really nice idea. We should discuss the exact syntax though :) Dart for example uses `${expr}` for interpolation or `$name` if the expression is just a name. I think it makes sense to have a special short syntax for the name case, because it is the most common one.

@nikic could you comment on the PR instead of commenting on each commit individually ? it would make it easier to see what is concerned in the PR.
---------------------------------------------------------------------------
by arnaud-lb at 2011/11/12 14:22:14 -0800
@nikic Thanks for your review, I'll take care of your remarks.
For the syntax, I have no preference. I've taken this one because it has the same semantics. In Ruby and Coffeescript the `#{...}` allows any expression between the brackets. In PHP the expression in the `${...}` must start with a variable name. As you mentioned Dart's `${...}` seems to allow any expression.
---------------------------------------------------------------------------
by nikic at 2011/11/12 15:03:48 -0800
@arnaud-lb If Ruby and Coffeescript use this, the #{...} syntax should be okay. Especially as ${...} might be confusing for PHP developers as it has the semantics of variable variables in PHP.
@stof Thanks, will do so next time.

@stof he doesn't need to - this is something github handles already. in the PR view, beside the "@nikic commented" bits, there's a set of links that shows where exactly the comment was in the format of commit sha, filename, and line inside the diff.
You can see for yourself right here, upper left:
---------------------------------------------------------------------------
by stof at 2011/11/13 01:20:38 -0800
@damianb The comment appears, but not the context in which the comment was. We have to follow each link to see it whereas comments done on the PR appear directly with their context. This is why I said it is easier when comments are on the PR.

So what about this now?
Btw, `REGEX_STRING` and `REGEX_DQ_STRING_PART` still are hardcoded and do not depend on the specified `interpolation` tags. But this looks hard to change, at least the regexes are quite complicated.
---------------------------------------------------------------------------
by arnaud-lb at 2011/12/02 15:22:45 -0800
I think I've addressed all issues (except hardcoding of `#{` and `}` in `REGEX_STRING` and `REGEX_DQ_STRING_PART`.)
Can this be merged after v1.4 is release if the syntax is accepted ?
---------------------------------------------------------------------------
by nikic at 2011/12/03 01:53:41 -0800
This would be my go for `STRING` and `DQ_STRING_PART` (isn't tested):
```php
<?php
$interpolChar = preg_quote(substr($options['interpolation'][0], 0, 1), '/');
$interpolPart = '[^' . $interpolChar . '"\\\\]*';
if (strlen($options['interpolation'][0]) > 1) {
$interpolRest = preg_quote(substr($options['interpolation'][0], 1), '/');
$interpolRegex = $interpolPart . '(?:(?:\\\\.|' . $interpolChar . '(?!' . $interpolRest . '))' . $interpolPart . ')*';
} else {
$interpolRegex = $interpolPart . '(?:\\\\.' . $interpolPart . ')*';
}
$this->options['dq_string_part_regex'] = '/' . $interpolRegex . '/As';
$this->options['string_regex'] = '/"' . $interpolRegex . '"|\'([^\'\\\\]*(?:\\\\.[^\'\\\\]*)*)\'/As';
```
It should allow both a single char interpolation syntax (like `{`) and multichar ones (like `#{`).
By the way, could we maybe move the compiled regexes out of `$this->options` into `$this->regexes`?

Help the developer when they specify an invalid filter by providing some...
... alternatives.
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Uses a simple `strpos` search (no fancy diff to determine what the filter could be). There is no impact to runtime performance because this is all happening during template compilation.
Examples:
```jinja
{{ my_entity|json }}
```
Shows exception:
`The filter "json" does not exist. Did you mean "json_encode"?`
```jinja
{{ my_date|dat }}
```
Shows:
`The filter "dat" does not exist. Did you mean "date"?`
```jinja
{{ my_var|f }}
```
Shows:
`The filter "f" does not exist. Did you mean "format", "default", "_default", "format_args", "format_args_as_text", "file_excerpt", "format_file", "format_file_from_text", "file_link"?`
Also good for custom filters created in your own domain `st_`:
```jinja
{{ my_var|st_ }}
```
Shows:
`The filter "st_" does not exist. Did you mean "st_friendly_date", "st_site_test_url"?`

Fixed bug that was trucating integers large then PHP_INT_MAX
The following code
{% set sizes = [7077888, 452984832, 28991029248, 1855425871872, 9223372036854775807] %}
{% for i in sizes %}
{{ i }}

7077888
452984832
2147483647
2147483647
