    <p>Since I rarely write my own regular expressions, this is one of few times I'm not sure where to begin. I am faced with a problem dealing with an unknown number of integers delimited with dashes. Since it's hard to visualize, I'll give an example...</p> <pre><code>LHZ345-347-348-349-362-363-LMZ323-342-344-345-346-180100- </code></pre> <p>Given this statement, a regex should return:</p> <pre><code>LHZ345-347-348-349-362-363- LMZ323-342-344-345-346-180100- </code></pre> <p>With this is mind, I need to write a regex that checks for a 3 A-Z characters followed immediately by a 3 digit integer. From then on, any number of 3 digit integer + dash pairs may follow except for the last digit pair which may be of any length. Only dashes, integers 0-9, and capital characters A-Z are used.</p> <p>If there are any regex geniuses out there willing to help me out if this is a simply enough problem, that would be awesome. If not, It would be great if you could direct me to a site that you feel would be helpful. Thanks in advance for any assistance! - Brandon</p> <p><strong>Edit 1:</strong> As to show some attempts, <code>[A-Z]{3}...\d+-</code> is all I have. To my knowledge this should work, but I'm stuck at the unknown number of integers in the middle part.</p> <p><strong>Edit 2:</strong> What changes to the regexes posted in the answers below are needed to accept dashes OR > signs in between the 3 digit integers? Also, I can't seem to input the regex into preg_match() and have all test cases work yet the same regex works in online testers such as regexpal.</p>

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.
