Search array for value.

[gammaman]

I have this function I am using which returns all the meta-data from a given website. I am trying to come up with something so that I can search the array that is returned to see if it contains a value.

Here is an example of what the function returns. Please also see my code comments

Array
(
    [title] => Video Games, Wikis, Cheats, Walkthroughs, Reviews, News & Videos - IGN
    [metaTags] => Array
        (
            [description] => Array
                (
                    [html] => <meta name="description" content="IGN is your site for Xbox 360, PS3, Wii, PC, 3DS, PS Vita &amp; iPhone games with expert reviews, news, previews, trailers, cheat codes, wiki guides &amp; walkthroughs" />
                    [value] => IGN is your site for Xbox 360, PS3, Wii, PC, 3DS, PS Vita & iPhone games with expert reviews, news, previews, trailers, cheat codes, wiki guides & walkthroughs
                )

            [robots] => Array
                (
                    [html] => <meta name="robots" content="noodp, noydir" />
                    [value] => noodp, noydir
                )

            [copyright] => Array
                (
                    [html] => <meta name="copyright" content="IGN Entertainment, Inc." />
                    [value] => IGN Entertainment, Inc.
                )

        )

)

I am trying to use something like the following to search the array

<?php
function recursive_array_search($needle,$haystack) {
	$count = 0;
    foreach($haystack as $key=>$value) {
        $current_key=$key;
        //if($needle===$value OR (is_array($value) && recursive_array_search($needle,$value) !== false)) {
		if(in_array($value)){
		    $count++; 
			echo "VIOLATION";
           // return $count;
        }
    }
    //return false;
	return $count;
}
?>

$link = getBaseURL();
      
$metadata = getUrlData($link)   //stores the meta-data from the website

$needle = array("PC","asadf");  //set of values to search for

$violation = recursive_array_search($needle,$metadata);  // I want this to return a count of 1 since the value PC is found in the meta-data

The problem I am having is that taking the following piece of the meta-data array


[description] => Array
(
[html] => <meta name="description" content="IGN is your site for Xbox 360, PS3, Wii, PC, 3DS, PS Vita &amp; iPhone games with expert reviews, news, previews, trailers, cheat codes, wiki guides &amp; walkthroughs" />
[value] => IGN is your site for Xbox 360, PS3, Wii, PC, 3DS, PS Vita & iPhone games with expert reviews, news, previews, trailers, cheat codes, wiki guides & walkthroughs
)


the value is one long string. I want to search this for single words. How can I achieve this?

Use strpos().
