Finding needle, in an array, based upon kind

[tgavin]

I can't put my finger on exactly how to do this. I want to check $string and $kind against $search. For example, if $kind == movie and $string contains '(widescreen)', we would have a match. However, if $kind == 'tv show' and $string contained '(widescreen)' we would not have a match. If $string contained '[region 2]', it wouldn't matter what $kind was, as it's a catchall and we would have a match.

$search = array();
$search = (
    '(widescreen)' => 'movie',
    '[region 2]' => '',
    '(director\'s cut)' => 'movie',
    'season 1' => 'tv show'
);

// match
$kind = 'movie';
$string = 'The Dark Knight (widescreen)';

// match
$kind = 'movie';
$string = "Meatballs (director's cut)";

// match
$kind = 'tv show';
$string = 'Frasier - season 1';

// no match
$kind = 'movie';
$string = 'The Dark Knight';

// match
$kind = 'tv show';
$string = 'Batman [region 2]'; 

Hopefully this makes sense!

Nope.

How is the searched data contained? Is it within an array, file, database...?

[AnthonySterling]

This seems to meet your initial outline and the specifications supplied, is it of any use?

<?php

/**
 * @param Array $aSearchParams The search parameters
 * @param String $sTitle The item title
 * @param String $sKind The item kind
 * @return Boolean
 */
function performSearch( $aSearchParams, $sTitle, $sKind )
{
    foreach ($aSearchParams as $sKindParam => $sTitleParam){
        if( (false !== strstr($sKind, $sKindParam)) && (false !== strstr($sTitle, $sTitleParam)) )
        {
            return true;
        }
    }
    return false;
}

$aSearchParams = array(
    '(widescreen)' => 'movie',
    '[region 2]' => '',
    '(director\'s cut)' => 'movie',
    'season 1' => 'tv show'
);

$sKind = 'movie';
$sTitle = 'The Dark Knight';

echo ( performSearch($aSearchParams, $sKind, $sTitle) ) ? 'Match.' : 'No Match.' ;

?>

It's in a string.
$string = $_POST['foo'];

I want to parse that string to see if there's a match. if there's a match, then die('error message');

Not at neat but explains the logic

$search = array( 
     'widescreen' => 'movie',
    '[region 2]' => '',
    '(directors cut)' => 'movie',
    'season 1' => 'tv show',
);

//match
//$kind = 'movie';
//$string = 'The Dark Knight (widescreen)';
// match
//$kind = 'movie';
//$string = "Meatballs (directors cut)";
// match
//$kind = 'tv show';
//$string = 'Frasier - season 1';
// no match
$kind = 'movie';
$string = 'The Dark Knight';
// match
//$kind = 'tv show';
//$string = 'Batman [region 2]'; 

$match=0;

foreach ( $search as $k=>$v ){

 if( $v == $kind && strpos( $string , $k ) ) {
  $match++;
 }elseif( strpos( $string, '[region 2]')){
  $match++;
 }

}

if( $match) echo 'Match ' . $kind .'-' . $string ;

Thanks guys!

SilverBulletUK, I think yours is the one that's gonna do it. However, I receive an error if trying to use the generic 'region 2'. prolly 'cause the field is empty.

So, what about changing that empty field to 'any' and then telling the function if that shows up in *any* string, regardless of movie, tv show, whatever, it's a match?

$aSearchParams = array(
    'region 2' => 'any',
);
// match
$sKind = 'TV Show';
$sTitle = 'Cops [region 2]';

// match
$sKind = 'Movie';
$sTitle = 'Hulk [region 2]'; 

it would probably be a good idea to make it case-insensitive as well. Which I was thinking of doing like this, unless there's a better way?

$sKind = strtolower('movie');
$sTitle = strtolower('The Dark Knight'); 

Thanks again, this is sweet!

[AnthonySterling]

What error are you getting? I don't seem to be getting any.

Here's the revised case-insensitive function.

/**
 * @param Array $aSearchParams The search parameters
 * @param String $sTitle The item title
 * @param String $sKind The item kind
 * @return Boolean
 */
function performSearch( $aSearchParams, $sTitle, $sKind )
{
    foreach ($aSearchParams as $sKindParam => $sTitleParam){
        if( (false !== stristr($sKind, $sKindParam)) && (false !== stristr($sTitle, $sTitleParam)) )
        {
            return true;
        }
    }
    return false;
} 

[Edit] I've found the error, let me have a quick play.

[AnthonySterling]

Bug fixed.

/**
 * @param Array $aSearchParams The search parameters
 * @param String $sTitle The item title
 * @param String $sKind The item kind
 * @return Boolean
 */
function performSearch( $aSearchParams, $sTitle, $sKind )
{
    foreach ($aSearchParams as $sKindParam => $sTitleParam){
        if( false !== stristr($sKind, $sKindParam) )
        {
            if( (empty($sTitleParam)) || (false !== stristr($sTitle, $sTitleParam)) )
            {
                return true;
            }
        }
    }
    return false;
}

Beautiful. Works like a charm!

Thank you very much
