    <p>I'm trying to extract all words from a string into an array, but i am having some problems with spaces (<code>&amp;nbsp;</code>).</p> <p>This is what I do:</p> <pre><code>//Clean data to text only $data = strip_tags($data); $data = htmlentities($data, ENT_QUOTES, 'UTF-8'); $data = html_entity_decode($data, ENT_QUOTES, 'UTF-8'); $data = htmlspecialchars_decode($data); $data = mb_strtolower($data, 'UTF-8'); //Clean up text from special chrs I don't want as words $data = str_replace(',', '', $data); $data = str_replace('.', '', $data); $data = str_replace(':', '', $data); $data = str_replace(';', '', $data); $data = str_replace('*', '', $data); $data = str_replace('?', '', $data); $data = str_replace('!', '', $data); $data = str_replace('-', ' ', $data); $data = str_replace("\n", ' ', $data); $data = str_replace("\r", ' ', $data); $data = str_replace("\t", ' ', $data); $data = str_replace("\0", ' ', $data); $data = str_replace("\x0B", ' ', $data); $data = str_replace("&amp;nbsp;", ' ', $data); //Clean up duplicated spaces do { $data = str_replace(' ', ' ', $data); } while(strpos($data, ' ') !== false); //Make array $clean_data = explode(' ', $data); echo "&lt;pre&gt;"; var_dump($clean_data); echo "&lt;/pre&gt;"; </code></pre> <p><strong>This outputs:</strong></p> <pre><code>array(58) { [0]=&gt; string(5) " " [1]=&gt; string(5) " " [2]=&gt; string(11) "anläggning" [3]=&gt; string(3) "med" [4]=&gt; string(3) "den" [5]=&gt; string(10) "erfarenhet" [6]=&gt; string(3) "som" } </code></pre> <p>If i check source for output i see that the first 2 array values is <code>&amp;nbsp;</code>.<br> No matter how I try, I can't remove this from the string. Any ideas?</p> <p><strong>UPDATE:</strong><br> After some tweaking with code i manage to get following output:</p> <pre><code>array(56) { [0]=&gt; string(1) "�" //Notice change. Instead of string length 5 it now says 1. But still its garbage. [1]=&gt; string(1) "�" [2]=&gt; string(11) "anläggning" [3]=&gt; string(3) "med" [4]=&gt; string(3) "den" [5]=&gt; string(10) "erfarenhet" [6]=&gt; string(3) "som" [7]=&gt; string(5) "finns" [8]=&gt; string(4) "inom" </code></pre> <p>Thanks!</p> <p><strong>ANSWER (for lazy people):</strong> </p> <p>Even thou this is a slightly different approach to the problem, and it never really answers why I had the problems I had above (like leftover <code>&amp;nbsp;</code> and other extra weird spaces), I like it and it is a lot better than my original code.</p> <p>Thanks to all who contributed to this! </p> <pre><code>//Clean data to text only $data = strip_tags($data); $data = html_entity_decode($data, ENT_QUOTES, 'UTF-8'); $data = htmlspecialchars_decode($data); $data = mb_strtolower($data, 'UTF-8'); //Clean up text from special chrs $data = str_replace(array("-"), ' ', $data); $clean_data = str_word_count($data, 1, 'äöå'); echo "&lt;pre&gt;"; var_dump($clean_data); echo "&lt;/pre&gt;"; </code></pre>

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
