Try this: <pre><code>$pattern='~\A(.+?) {2,}(.+?)\R{2,}(.+?)\R{2,}(.+?)(?:\R{2,}|\Z)~s'; preg_match($pattern, $subject, $match); </code></pre> <a href="http://ideone.com/oSQDx" rel="nofollow">See it in action on ideone.com</a> I'm assuming all those <code>&nbsp;</code>'s in your sample text represent regular spaces, and you only used them so we could see that there was more than one space. If you been using SO's code formatting from the beginning, that wouldn't have been necessary. That's the indentation style of formatting; in text formatted with backticks, whitespace still gets collapsed. I'm also assuming you're reading the whole file into memory, not processing it line-by-line. The regex is pretty straightforward. Starting at the beginning of the text (<code>\A</code>), it reluctantly matches and captures everything it sees (<code>(.+?)</code>, in single-line mode) until it sees two or more consecutive spaces (<code>{2,}</code>). After that, it reluctantly matches and captures until it sees two or more newlines in a row (<code>(.+?)\R{2,}</code>). Then it does the same thing twice more to capture the second and third paragraphs. The final <code>(?:\R{2,}|\Z)</code> is there in case there's no more text after the third paragraph. <code>\R</code>, if you're not familiar with it, is a shorthand for any kind of line separator: <code>\n</code>, <code>\r</code>, <code>\r\n</code> and a few other, less common ones. It's supported by Perl, PHP (PCRE), Ruby 1.9+ (Oniguruma) and a few other flavors, but not (so far) by JavaScript, Python, Java or .NET.

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.
