What exactly do you need to do?

This works for me: $pages =<<<TEXT <li class="page_item page-item-27"><a href="http://www.domain.tv/news/" title="News">News</a></li> <li class="page_item page-item-30"><a href="http://www.domain.tv/resources/" title="Resources">Resources</a></li> <li class="page_item page-item-31"><a href="http://www.domain.tv/submit/" title="Submit">Submit</a></li> TEXT; $pages = preg_replace('~\s*class="page_item page-item-[0-9]+"\s*~', '', $pages); echo $pages; Output: <li><a href="http://www.domain.tv/news/" title="News">News</a></li> <li><a href="http://www.domain.tv/resources/" title="Resources">Resources</a></li> <li><a href="http://www.domain.tv/submit/" title="Submit">Submit</a></li>

Post your exact code and what you're exactly trying to match, I tested the code I posted with what you provided and it worked fine.

And to do something like that this should work: $new = array(); foreach($withoutBreaks as $val) { $parts = explode(' ', $val); $new[substr(array_shift($parts), 1)] = implode(' ', $parts); } I made the assumption that the first word is the name and the rest is the value. Wasn't completely sure if it should be like 'Site Room' => 1 or 'Site' => 'Room 1', this code should do the latter.

I was thinking you could do something like this, to avoid having to do multiple preg_*() calls (but I wasn't sure which would be faster, so I did a benchmarking test): preg_match_all("/(?<=\A|[^A-Za-z0-9_])@([A-Za-z0-9_]+)(?=\Z|[^A-Za-z0-9_])/", $text, $matches); for($i = 0, $n = sizeof($matches[0]);$i < $n;++$i) { $text = str_replace($matches[0][$i], "<a href='/user/{$matches[1][$i]}' target='_blank'>{$matches[0][$i]}</a>", $text); } // Use $matches[1] for the usernames to notify Ran 1000 times took an average of about 0.15 Seconds This turned out to actually be faster: $text = preg_replace("/(?<=\A|[^A-Za-z0-9_])@([A-Za-z0-9_]+)(?=\Z|[^A-Za-z0-9_])/", "<a href='/user/$1' target='_blank'>$0</a>", $text); preg_match_all("/(?<=\A|[^A-Za-z0-9_])@([A-Za-z0-9_]+)(?=\Z|[^A-Za-z0-9_])/", $text, $matches); // Use $matches[1] for the usernames to notify Ran 1000 times took an average of about 0.10 Seconds Just because I was curious I ran my original solution through too, and that took an average of about 0.085 seconds / 1000 loops.

You misunderstood the question. mapleleaf was simply asking how to search a string of words for a certain word and did not want, for example, "Color" to match because "Colorado" was in the string.

Something like this? $string = preg_replace('~\s*class="page_item page-item-[0-9]+"\s*~', '', $string);

In your array it's [EventDate 2010.06.18 not [Date 2010.06.18 Edit: Since you modified your post it leads me to believe you want something more like this: foreach($withoutBreaks as $key => $val) { if(substr($val, 0, 11) == '[EventDate ') { echo "Key: $key<br />\n"; break; } }

You can use preg_match along with the \b modifier. if(preg_match("~\b{$_GET['word']}\b~", $file)) { // Found } else { // Not found }

You can't get the MAC address of a visitor in PHP. You'll have to look into another method of user verification.

Use preg_replace_callback, and in the callback you can do whatever you need to do to each match. It might look something like this: $text = preg_replace_callback( "/(?<=\A|[^A-Za-z0-9_])@([A-Za-z0-9_]+)(?=\Z|[^A-Za-z0-9_])/", create_function( '$matches', /* do whatever you need to do */ 'return "<a href=\'/user/{$matches[1]}\' target=\'_blank\'>{$matches[0]}</a>";' ), $text );

Yea, this is a much better idea. Using $_SERVER['PHP_SELF'] leaves you open to XSS attacks. Or if you want it to be 'valid' you can just put the name of the file.

Oh yeah, I meant to mention that in my post as well. I think 3 would be the best.

No. You will have to use OR like so: SELECT * FROM table WHERE col LIKE '%something%' OR col LIKE '%somethingelse%' If you have an array containing terms you want to use with LIKE you can do something like this: $terms = array( 'term1', 'term2', 'term3' ); $sql = "SELECT * FROM table WHERE col LIKE '%" . implode("%' OR col LIKE '%", $terms) . "%'";

You can use imagecolortransparent to set a color to transparent on the image.

Use urlencode to encode the & for the url.

Well that's what I get for blindly looking at the code I guess. You don't need the single quotes there regardless. $sql = "SELECT * FROM $table";

$_REQUEST = array_map('urldecode', $_REQUEST);

Your first error is because single quotes don't have variable interpolation. Meaning that in this statement: $sql = 'SELECT * FROM "$table"'; $table is being taken as a literal string, not a variable. So you need to do this: $sql = "SELECT * FROM '$table'"; You're also forgetting a $ here: function listQuery(categories, $connection) { It should be: function listQuery($categories, $connection) {

You need to pass the connection, $connection in your case, to mysqli_error().

Are you sure you have the GD library installed? Use phpinfo to see if you do.

You should really look into variable scopes. Your problem is that $connection is not defined within your function, listQuery(). One solution is to pass $connection as a parameter like so: require_once("/functions/db_fns.php"); $connection = dbConnect(); echo listQuery("categories", $connection); function listQuery($table, $connection) { // prepare the SQL query $sql = 'SELECT * FROM $table'; $result = $connection->query($sql) or die(mysqli_error()); // find out how many records were retrieved $numRows = $result->num_rows; while ($row = $result->fetch_assoc()) { echo strtoupper("<li>{$row["cat_name"]}</li>"); } }//end function

Look into mod_rewrite. If you have further questions about mod_rewrite there's a board you can ask questions on here.

The first parameter has to either be a string of name of the class you're testing or either an instance of the class. So in your example either 'test' or $test. The second parameter has to be a string, 'test2'. if (method_exists($test, 'test2')){ echo "found method"; } or if (method_exists('test', 'test2')){ echo "found method"; }
