    <p>You misunderstand the difference between <a href="http://php.net/manual/en/language.types.string.php" rel="nofollow">strings</a> and <a href="http://php.net/manual/en/language.types.array.php" rel="nofollow">arrays</a> in PHP. Distinguishing between the two is <strong>critical</strong>. I'll assume your data is in string format.</p> <p>String manipulation to the rescue! If there's no identifiable pattern or format to your data, extracting the desired information will be difficult. If your string <em>always</em> begins with <code>test type:</code> and the value following it <em>always</em> ends with a semicolon, you might do something as follows (not ideal, but it's simple):</p> <pre><code>$str = 'test type: human; Including all the test; number of participants 2 persons + additional $50'; $testType = substr($str, 11, strpos($str, ';')-11); // 11 == len('test type: ') </code></pre> <p>Similarly, if your string always contains the text <code>number of participants</code> immediately before the desired data, and if there is a space immediately after that data, you might use:</p> <pre><code>$start = strpos($str, 'number of participants') + 23; $numPart = substr($str, $start, strpos($str, ' ', $start+1) - $start); </code></pre> <p>I hardcoded the indices for brevity, but they're easily replaced with string search functions (especially regex).</p> <p>Resources:</p> <ul> <li><a href="http://php.net/manual/en/ref.strings.php" rel="nofollow">String Functions in PHP</a></li> <li><a href="http://php.net/manual/en/function.substr.php" rel="nofollow"><code>substr</code> (substring)</a></li> <li><a href="http://php.net/manual/en/function.strpos.php" rel="nofollow"><code>strpos</code> (basic search)</a></li> </ul>

    1. COGranted, it answers and uses the OP's current code (so no downvote), but isn't this crying out for an `array()`?

    2. COHow so? His question is related to string manipulation, not array syntax. Would you prefer to instead split the string into an array and lose the ability to perform search operations on it?

    3. COTheir question is about arrays. The title and first sentence is asking about arrays. "I am looking for retrieving specific data from an array". The code looks like it should be handled with an array, not regex on what is likely to be different text each DB query. The fact they misunderstand what an array is and so used a variable/string doesn't therefore define the question :)

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.
