Question about Array keys--in reverse!

[sfullman]

Hi there,

suppose I had the following complext aarray keys and values

$fDOM['form']['formname']['id']=9000;
$fDOM['form']= 'myForm';
$otherArr[1][3][0] = 9000;
$otherArr[1][3][1] = 7000;

I'm just kind of making these up but they represent some of the complexity I need to work with.

Now, here's the question -- in English-- that I want to ask in "php":

"Give me tne array name, and the key indices in order, of any array variable that has value of 9000."

What I want to get back is the following:
(fDOM, form, formname, id)
(otherArray, 1, 3, 0)

Is there ANY way to do this at all using PHP? Certainly someone has thought of this!

Thanks in advance.

The code is nightmarish, but the usage is simple:
$results = array_search_r($needle, $haystack);

Where needle represents the string or number you seek and haystack is the complex array.

This function returns an array of arrays, where the first dimension is the result number, and the second dimension represents each step inward. For example, in your array above this function would return:

$results[0][0] = form
$results[0][1] = formname
$results[0][2] = id

If you have trouble with it let me know, this was a bugger to get working reliably. Fortunately I can use this in my own work.

function array_search_r($needle, $haystack, $path = null) {
	static $resultCount = 0;
	static $results = array();
	do {

		if (is_array($val)) {
			$path[sizeof($path)] = $key;				
			array_search_r($needle, $val, $path);
		} else if ($val == $needle) {
			$path[sizeof($path)] = $key;
			$results[$resultCount] = $path;
			unset($path[sizeof($path) - 1]);
			$resultCount++;

		}
	} while (list ($key, $val) = each ($haystack));
	return($results);
}

I will take a look at this thanks.

BTW Majic, I'm interested in writing some articles for phpbuilder.com, and I also have some scripts I'd like to submit. I tried emailing once but no response. Know anyone I could speak to? Thought you might be associated with the site.

For an example, here's a script I developed for testing PCRE expressions:

http://samuelfullman.com/team/php/tools/regular_expression_tester_p.php

Here are some sample strings that can be used with this (give them a try!):

Find a select element on a form:
/<\sselect\s[^>]\s>\s((<\soption\s>\s[^<]\s)|(<\soption\s[^>]+\s>\s[^<]\s)|(<\soption\s[^>]+\s>\s[^<]\s<\s\/option\s>\s))+\s<\s\/select\s*>/i

Find a form:
/(<form\s[^{>]((name\s=\s'['} "]+'\s)|(name\s=\s"[^' "]+"\s)|(name\s=\s[^' "]+\s))[^>]>)((.)|(\s))?(<\s\/form\s*>)/i

Find an href:
/<\sa\s[^>]href\s=\s("?|'?)[^{>]+("?|'?)[>]>.?<\s\/a\s*>/i}

my email is [e-mail]

Thanks

I wish I was associated with this site, because my account is messed up and I need it fixed. Unfortunately no one has returned my e-mails regarding it. I'm currently working on my own PHP development website. I'm going to need some contributors when it's ready, are you interested?

[sfullman]

Yes, definitely, I also have another idea for tech people like ourselves which you may be interested in. My email, again, is [e-mail].

Give me an email sometime outside the forum and let's touch bases.

Did you try that URL?
