Using this string:
{$var1: $var2}
of course it doesn't work as some might expect.
But why in the name of [whatever, too many to list] doesn't this one
below work?
\{$var1: $var2}
If \ is an escape character why does it also appear in the string output?
Why does the above \ escape {$var1 and not only the {?
Miserable.
First up:
http://uk2.php.net/manual/en/language.types.string.php#language.types.string.syntax.double
Excerpt:
Again, if you try to escape any other character, the backslash will be
printed too! Before PHP 5.1.1, backslash in \{$var} hasn't been
printed.
Then:
http://uk2.php.net/manual/en/language.types.string.php#language.types.string.parsing.complex
Excerpt:
Since you can't escape '{', this syntax will only be recognised when
the $ is immediately following the {. (Use {\$ to get a literal
{$).
Does that help?
HTH,

Not really, John.
===
$var1 = 1; $var2 = 2;
print({\$var1: $var2});

will output {$var1: 2}. I need this output {1: 2}.
What I need is an escape character for the {, but it looks like
PHP doesn't have any.

Horrendous workaround.

Within a quoted string, you can surround variable names with braces for
clarity. This is especially helpful for situations like this, where the
rest of the string interferes with syntax.
Heh. It was a rhetorical question. He said there was no way to escape
the {'s
Of course there is... that was my point.
I suggest you bring yourself up to speed on what escaping really means.
Your suggestion under no circumstances escaping.
Actually, PHP Documentation does mention it:
Since you can't escape '{', this syntax
See here(thanks go John Wells for posting about it):
http://uk2.php.net/manual/en/language.types.string.php#language.types.string.parsing.complex
Now you may go on a rampage about what escaping means, but honestly, I
don't want to hear about it.

Don't use it is my solution.

Bingo. That is what I am trying to do. But I am not allowed since there
is no escaping for this thing.
Thanks all for the replies. My intention was to bring to light YA PHP
design problem. Looks to me like I didn't really succeed, but at least
it's out.

Re: [PHP] Miserable escape string problem
Is this really worth all the keystrokes? Do we not have any more valuable
ways to spend our time?

Good point Dave. But on the wrong side.
By counting all the keystrokes the PHP developers have to type extra
for code like this:
{{$foo}: {$bar}}
'{'.$var1.': '.$var2.'}'
etc.
vs. such code
\{$foo: $bar}
and actually not accounting for the ease of reading and assimilating
such code, guess what's better? Ramp about it? Or try rise the problem?

My prefered way is definitely this one. It's simple really, let me sing
it for you...
in, out... in, out... shake it all about... ;)
When adding variable data to strings, by using the in, out (shake it all
about method), the technique is identical whether you are using object
properties, nested array fields, simple variables, functions, constants.
That's right, I said one way fits every last one of them, try that with
your precious interpolation :B Interestingly, it also happens to be the
fasted method from a processor standpoint :)
Cheers,
Rob.

I have a PHP coprocessor embedded in my skull, it's all easy to read...
well as long as the braces are properly formatted anyways *haha* ;)
