[RESOLVED] Getting a value out of a multidimensional array

[spivey]

I have been tearing through the PHP books trying to find out how to do what I'm trying to do.

I have a multidimensional array:

Array ( [errorCode] => 0 [errorMessage] => [results] => Array ( [http://the_url_being_shortened] => Array ( [hash] => CRWYp [shortKeywordUrl] => [shortUrl] => http://bit.ly/18jXxp [userHash] => 18jXxp ) ) [statusCode] => OK ) 

I want to grab the value for the key [shortUrl] and write it into a document.

I have assigned the array to a variable, "$url". I have tried to do stuff like:

print_r($url['results']['shortUrl']);

but that doesn't get me to the value.

How do I parse the array to get to this value, in the above example, "http://bit.ly/18jXxp" so I can add it to my fwrite statement?

Thanks

The problem is the array you are starting with. IT looks like it is using "[http://the_url_being_shortened]" as the key for the nested array that contains shortURL. You might want to revisit the code that generates your multidimensional array and sort that out.

The result print_r() returned would have been formatted like this:

Array
(
	[errorCode] => 0
	[errorMessage] =>
	[results] => Array
		(
			[http://the_url_being_shortened] => Array
				(
					[hash] => CRWYp
					[shortKeywordUrl] =>
					[shortUrl] => http://bit.ly/18jXxp
					[userHash] => 18jXxp
				)
		)
	[statusCode] => OK
)

(If you're displaying it in a browser, use <pre></pre> tags or just view the page source itself instead of the rendered HTML).

Which shows that, as sneakyimp says, that the 'shortUrl' key is nested three levels deep: $url['results']['http://the_url_being_shortened']['shortUrl'].

Hi,
u could try this:

$count = count ($YourArray);
for ($i=0; $i<$count; $i++){
$countmore=count($YourArray[0]);
for ($j=0; $j < $countmore; $j++){
//print ($YourArray[$i][$j] . "<br> ");

$text =$YourArray[$i][$j];
//echo $text ;
$str = stristr ($text, "SearchedValue");
echo $str ;

Hope this could be helpful.

Hm. I tried that, but using the variable for the url when it is passed from the form input (a user inputs a url in a form:

$formurl = $_POST['input_url'];

So I tried

$url['results'][$formurl]['shortUrl']

but that didn't work.

When one level fails, the best thing to do is start stepping through them.

<pre><?php
echo 'Posted URL: '.$_POST['input_url']."\n\n";

$formUrl = $_POST['input_url'];

print_r($url)."\n";
print_r($url['results'])."\n";
print_r($url['results'][$formUrl])."\n";
print_r($url['results'][$formUrl]['shortUrl'])."\n";
?></pre>

Something somewhere along the way is not equalling what you think it does. I'm guessing that the posted URL and the url used for the key are different.

bpat1434, I had to go back and make sure I was grabbing the submitted value. I got it and it works. Thanks!
