    <p>Hey all. I have a string of names separated by commas. I'm exploding this string of names into an array of names with the comma as the delimiter. I need a RegEx to remove a white space(if any) only after the comma and not the white space between the first and last name.</p> <p>So as an example:</p> <pre><code>$nameStr = "Sponge Bob,Bart Simpson, Ralph Kramden,Uncle Scrooge,Mickey Mouse"; </code></pre> <p><strong>See the space before Ralph Kramden?</strong> I need to have that space removed and not the space between the names. And I need to have any other spaces before names that would occur removed as well.</p> <p><strong>P.S.:</strong> I've noticed an interesting behavior regarding white space and this situation. Take the following example:</p> <p><strong>When not line breaking an echo like so:</strong></p> <pre><code>$nameStr = "Sponge Bob,Bart Simpson, Ralph Kramden,Uncle Scrooge,Mickey Mouse"; $nameArray = explode(",", $nameStr); foreach($nameArray as $value) { echo $value; } </code></pre> <p><strong>The result is:</strong> Sponge BobBart Simpson Ralph KramdenUncle ScroogeMickey Mouse </p> <p><strong>Notice the white space still there before Ralph Kramden</strong></p> <p>However, when line breaking the above echo like so:</p> <pre><code>echo $value . "&lt;br /&gt;"; </code></pre> <p>The output is:</p> <p>Sponge Bob</p> <p>Bart Simpson</p> <p>Ralph Kramden</p> <p>Uncle Scrooge</p> <p>Mickey Mouse</p> <p><strong>And all of the names line up with what appears to be no white space before the name.</strong></p> <p><strong>So what exactly is PHP's behavior regarding a white space at the start of a string?</strong></p> <p>Cheers all. Thanks for replies.</p>

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.
