    <p>Regex is an overkill in this case.</p> <p><strong>From the <a href="http://php.net/urlencode" rel="nofollow">urlencode manual</a>:</strong></p> <blockquote> <p>Returns a string in which all non-alphanumeric characters except <code>-_.</code> have been replaced with a percent (<code>%</code>) sign followed by two hex digits and spaces encoded as plus (<code>+</code>) signs. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-www-form-urlencoded media type. This differs from the <a href="http://www.faqs.org/rfcs/rfc3986" rel="nofollow">» RFC 3986</a> encoding (<strong>see <a href="http://php.net/rawurlencode" rel="nofollow"><code>rawurlencode()</code></a>) in that for historical reasons, spaces are encoded as plus (<code>+</code>) signs</strong>.</p> </blockquote> <p>It clearly states that if you want spaces to be encoded as <code>%20</code>, and not <code>+</code>, you should use <a href="http://php.net/rawurlencode" rel="nofollow"><code>rawurlencode()</code></a>.</p> <p><strong>Code example:</strong></p> <p> <pre><code>$strings = array( '36 2543541284', '1234 5678', 'this is a string' ); $strings_encoded = array(); foreach($strings as $string) { $strings_encoded[] = rawurlencode($string); } var_dump($strings_encoded); </code></pre> <p><strong>Outputs:</strong></p> <pre><code>array(3) { [0]=&gt; string(15) "36%202543541284" [1]=&gt; string(11) "1234%205678" [2]=&gt; string(22) "this%20is%20a%20string" } </code></pre>

    1. COI understand why your answer describes url encodings, as that is the subject of the OP's question and he may find the information useful. But the actual issue is that the regex wasn't matching the input strings correctly regardless of how the spaces were encoded - whether as `+` or `%20` or left simply as whitespace. Your 'overkill' comment does not make sense in this context.

    2. CO@MikeM OP was obviously looking for an easier way out, hence his comment on having tried urlencode already (**From OP: I have also tried urlencode but to no avail.**). My answer is very much relevant. His goal is to encode a URL, and I posted the easiest way.

    3. CO@thordarson, sorry good people. I didn't know that we still have conversations going on about the post. Both of you have really good points. Initially, I was looking for url encode that would add something like %20 to a space. However, even that didn't solve my problem when I did it manually. Truth is that the goal was to have a single space after first 2 digits and Mike's solution of adding \s to ND provided that solution. I am still having issues though as something still isn't right. I will post shortly. Thanks to all of your for your kindness at StackOverflow forum.

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.
