How to "unlock" any text at the time of "echo" and turn each word into a link

Question

I made a database and in this database register a phrase, I would like that when I was going to give the "echo" in that sentence, each word would become a unique link. Ex:

recue o código em 4 espaços

The phrase is simple, but I would like each word to create a link. The purpose of this is to improve the search media.

In the example phrase is the word code. In case I click on the word code I’d like to go to a search page that uses that word.

Using the word is simple, the biggest problem is unlocking that phrase and turning each word into a link.

Answer 1

This is a tag system, usually keywords and not part of a text. They should be individual and not a phrase.

$str = 'recue o código em 4 espaços';
$str = explode( ' ' , $str );

foreach( $str as $palavra )
{
    if( mb_strlen( $palavra ) > 3 )
    echo '<a href="'.$palavra.'">'.$palavra.'</a>';
}

Note that each word will be a link. I added a check to accept words longer than 3 characters.

Javascript:

To break that sentence in the blanks you can do it this way:

var frase = 'recue o código em 4 espaços';
var palavras = frase.split(' ');
var links = palavras.map(function(palavra) {
    var link = document.createElement('a');
    var casulo = document.createElement('div');
    link.href = '?busca=' + palavra;
    link.innerHTML = palavra;
    casulo.appendChild(link);
    return casulo.innerHTML;
});
document.getElementById('resultado').innerHTML = links.join(' ');

<div id="resultado"></div>

This is a simplified way, could join more checks as for example delete short words like ou, a, é etc....

The variable links will have an array of anchors with word text.

Answer 3

And let the games begin! D

Another approach:

$str = 'recue o código em 4 espaços';

echo implode( ' ',

    array_map(

        function( $word ) {
            return sprintf( '<a href="%1$s">%1$s</a>', $word );
        },

        explode( ' ', $str )
    )
);

If you do not want the words to remain united by a space the way they were before the substitution, simply remove the implode().
