Implode string problem

[glinky]

Hi,

 

I´m building a search module for a website and I wrote a function to take out undesirable extra spaces from a string. This way I will only get a single space between words.

The function is this:

 

function cleanSpaces($string){

	$newString = explode (' ', $string);
	$array_dimension = count($newString);

	for ($i=0;$i<$array_dimension;$i){
		if($newString[$i] == ' ' || $newString[$i+1] == ' '){
		unset($newString[$i+1]);	
		}else{
		$i++;	
		}
	}

	$string = implode(' ',$newString);

	return $string;
} 

 

 

The problem is that after this function returns the new string (and it returns it right cause I tested) a query to the Database can´t no longer find the searched words.

 

Example: If I search for "two clocks" the query to Db will find it and give me back the result. But if I search for "two      clocks" my function turns it to "two clocks" but que query to Db is now empty.

 

Is there some king of problem with the blank space enconding??

 

Apreciate some Help!

Thanks

Your function looks fine, could you show us the code that does the query?

Hi

 

Thanks for qe quick answer!

 

my query is this:

 

$search = cleanSpaces($get);
$query = "SELECT * FROM conteudos WHERE titulo like '%$search%' OR subtitulo LIKE '%$search%'";

 

 

[ReKoNiZe]

Your query looks fine, try making it echo your query so you can see if you have any weird spacing or anything.

Correction ...sorry

 

There was and extra "OR" that doesnt make sense...

 

Query:

$search = cleanSpaces($get);
$query = "SELECT * FROM conteudos WHERE titulo like '%$search%'";

[glinky]

I echo the query and it looks the fine...

 

SELECT * FROM conteudos WHERE titulo like '%two clocks%'

 

I really can´t understand this...

[ReKoNiZe]

Try changing it to WHERE titulo='$search' to see if that changes anything

[glinky]

I tried that before and nothing...

[ReKoNiZe]

Hmm.. Show us more code if you can then, sounds like it should work fine.

[glinky]

Im not getting the searched value from a form because Im testing it so it comes from the var $get

Theres also another function running but it´s after the query (as you can see ) so i soudn´t be because of that...

 

$get = "two    clocks";
$search = cleanSpaces($get);
$searched = array();
$query = "SELECT * FROM conteudos WHERE titulo like '%$search%'";
echo $query;
$result = mysql_query($query)or die(mysql_error());	
	while ($row = mysql_fetch_assoc($result)) {

		$titulo = $row['titulo'];
		$texto = $row['texto'];

		$words = LimpaString($titulo, $get);

		if ($words != null){
			$titulo = highlightWords($titulo, $words);
			$texto = highlightWords($texto, $words);
			echo "<a href='search.php?section=".$row['section']."'>".$titulo."</a>"."<br>".$row['subtitulo']."<br><br>".$texto."<br><br><br>";
			$searched[]=$row['id'];
		}
	}

[ReKoNiZe]

That doesn't make. It should work, I'm not 100% why its not working. Your function must be adding some character we can't see.

[glinky]

The problem ist´s actually in that other function...

 

I´m sorry I´ve been wasting your time...

 

I´m posting all the code including tha other function ... but I dont know if it is too big for you to take a look at ( I might think that because I´m not a PHP Pro).

 

Anyway it worked before I used that cleaSpaces function...so I really can´t figure this out!

mysql_select_db("search");
mysql_query("SET NAMES 'utf8'");
mysql_query('SET character_set_connection=utf8');
mysql_query('SET character_set_client=utf8');
mysql_query('SET character_set_results=utf8');

function LimpaString($string,$search, $enc = 'UTF-8'){

$acentos = array(
    'A' => '/À|Á|Â|Ã|Ä|Å/',
    'a' => '/à|á|â|ã|ä|å/',
    'C' => '/Ç/',
    'c' => '/ç/',
    'E' => '/È|É|Ê|Ë/',
    'e' => '/è|é|ê|ë/',
    'I' => '/Ì|Í|Î|Ï/',
    'i' => '/ì|í|î|ï/',
    'N' => '/Ñ/',
    'n' => '/ñ/',
    'O' => '/Ò|Ó|Ô|Õ|Ö/',
    'o' => '/ò|ó|ô|õ|ö/',
    'U' => '/Ù|Ú|Û|Ü/',
    'u' => '/ù|ú|û|ü/',
    'Y' => '/Ý/',
    'y' => '/ý|ÿ/',
    'a.' => '/ª/',
'a.' => '/ª/',
    'o.'=> '/º/'
);

// Limpar o texto onde procurar
    $newString = preg_replace($acentos, array_keys($acentos), htmlentities($string,ENT_NOQUOTES, $enc));
$newString = ereg_replace("[^a-zA-Z0-9 ]", "", strtr($newString, "-", " "));
$newString = strtolower($newString);
// Limpar o texto procurado
$search = preg_replace($acentos, array_keys($acentos), htmlentities($search,ENT_NOQUOTES, $enc));
$search = ereg_replace("[^a-zA-Z0-9 ]", "", strtr($search, "-", " "));
$search = strtolower($search);

//Separar os textos em palavras
$palavrasNewStr = explode(' ',$newString);
$palavrasStr = explode(' ',$string);
$palavrasSearch = explode(' ',$search);

//Contar palavras do texto procurado
$searchLength = count($palavrasSearch);

$words = array();
//Se a busca tiver mais que 1 palavra
if($searchLength>1){
	for( $i=0; $i < $searchLength; $i++ ){
		$search = $palavrasSearch[$i];
		$position = array_search( $search , $palavrasNewStr );
		if($position != null){
			$words[]=($search);

				$numLetras = count($letrasPalavra);
				if( $letrasIguais >= ($numLetras)/2 && $numLetras > 2 ){
					$words[$i] = $palavrasStr[$i];
					//return $words;
				}
			}return $words;	

		}
		}return $words;

}else{

	$position = array_search( $search , $palavrasNewStr );

	if($position != null){
			$palavra = $palavrasStr[$position];	
			$words[$i] = $palavra;
			return $words;

					//return "sdsdgsfg";
					//return $words;

			return $words;
