PHP - Preg_replace Matching @username
Hi
I'm trying to match @USERNAME in a string and replace it with @<a href="message.php?member=USERNAME">USERNAME</a> I've tried a few different methods: Code: [Select] preg_replace ('/@(.*?)/', '<a href="message.php?member=$1">$1</a>', $str)and also * and \@ but i just can't seem to get it to work. any help would be appreciated!

Using Inline Php; <h1><font Color="000088">the Username <?php '.$username.' ?> Already Exists";</h1>
I am wanting to replace certain words to make them bold and also linked. The code below is working however it is also replacing images that have the same filename therefore causing the image to be broken. How can I replace the word when it appears without replacing the filename when it appears. <?php $find = array ("/$word/i","/A Duty of Care/i"); $replace = array ("<a href=/link.php?word=$word><b>$word</b></a>","<a href=/link.php>A Duty of Care</a>"); Echo preg_replace ($find, $replace, $definition); ?> ISSUE. A User enters information into a form. If the 'username' is already taken, a 'message' in Red and with larger font-size will be returned, for example, "The username $username already exists." If the username is 'mattd' then the message should say, "The username mattd already exists." Within my php application, I have included 'inline html'. Here is part of the code: .... if (mysql_num_rows($query_run)==1) { // it will never = more than one because only //one user will or will not exist ?> <html> </body> <h1><font color="#FF0066">The username <?php echo $username; ?>already exists.</h1> </body> </html> <?php }else{ //start the registration process $query = "INSERT INTO `Names` VALUES .... 1. At one point I did get this: "The username mattd already exists." 2. But now I only get "The username already exists." I am not retrieving the $username variable. This screenshot is found he http://imgur.com/lIwLZ1G thanks. While we're on the subject, is there a way to ensure that the first letter of a name is captalized, and the rest lowercase? Or is this best handled later on, when the name is being used and called from the DB. PS: some of us comment are code as to WHAT we are doing because we're just not that good yet, and we need to explain it to ourselves. Wondering if someone could help me. What I am trying to do is display the information from each row. I am trying to read from 2 tables and display them on a page. I want them to show like this name,make,type, price,"images/listings/a1.jpg,images/listings/a2.jpg,images/listings/a3.jpg,images/listings/a4.jpg,images/listings/a5.jpg,images/listings/a5.jpg" name,make,type, price,"images/listings/b1.jpg,images/listings/b2.jpg,images/listings/b3.jpg,images/listings/b4.jpg,images/listings/b5.jpg,images/listings/b5.jpg" Example. the table structures are as so: Code: [Select] listings -------------------------------- id name make type price (then a couple more columns I dont need data from) -------------------------------- 1 name1 make1 type1 price1 2 name2 make2 type2 price2 3 name3 make3 type3 price3 listimages ---------------------------------------------------- id imagepath mainimage listingid ---------------------------------------------------- 1 images/listings/a1.jpg 1 1 2 images/listings/a2.jpg 0 1 3 images/listings/a3.jpg 0 1 4 images/listings/a4.jpg 0 1 5 images/listings/a5.jpg 0 1 6 images/listings/a6.jpg 0 1 7 images/listings/b1.jpg 1 2 8 images/listings/b2.jpg 0 2 9 images/listings/b3.jpg 0 2 10 images/listings/b4.jpg 0 2 11 images/listings/b5.jpg 0 2 12 images/listings/b6.jpg 0 2 13 images/listings/c1.jpg 1 3 etc Here is the code I am using. Everything works except some of the listing images don't match up to the names. I think when certain names don't have pictures it just moves up the images to the next person. I need to somehow associate the listingid column from listimages table with the id column from the listings table. The mainimage column tells what image of the group of images is default for that name. 1 being the default 0 not the default Here is the code I am using. Code: [Select] <?php // Make a MySQL Connection mysql_connect("localhost", "xxxxxx", "xxxxxx") or die(mysql_error()); mysql_select_db("xxxxxx") or die(mysql_error()); $result = mysql_query("SELECT * FROM listings l JOIN listimages li ON l.id = li.listingid ORDER BY l.id DESC") or die(mysql_error()); $last_listingid = null; $curRow = array(); while($row = mysql_fetch_array($result)) { // Check for a difference in listing ID - and if it is, then we should show the previous row first if ($last_listingid != $row['listingid'] && $last_listingid !== null) { // Implode the array with quotes around it echo $row['name']; echo ","; echo $row['make']; echo ","; echo $row['model']; echo ","; echo $row['type']; echo ","; echo $row['price']; echo ","; echo '"' . implode(',', $curRow) . '"<br />'; // And start fresh $curRow = array(); } // Now we can save it to the array $curRow[] = $row['imagepath']; // And set the new ID $last_listingid = $row['listingid']; } // Finally, we'll need to implode it one last time since there should always be at least one value in the array echo '"' . implode(',', $curRow) . '"'; ?> Please let me know what I am doing wrong Anyone Thanks Hi, I am in the procress of creating discussion system however I am a bit puzzled about the best way to go about it. I am starting the discussion by creating an ID number and then match the answer to the initial ID number. However, I dont know whether if is best to put the responses into a different database. I'm a bit puzzled how ID matching systems works. Lets say: Question 1 = ID1 Question 2 = ID2 Question 3 = ID3 Question 1 Answer 1 = ID4 (How is this matched to ID1) Question 2 Answer 1 = ID5 (How is this matched to ID2) is this based on preg_match? Basically i want to take an array of numbers let's say: Code: [Select] <? $array1=array("1","2","3","4"); ?> Now say i reprint that same array, but the 3 is missing. Code: [Select] <? $array2=array("1","2","4"); ?> How would i print what's missing from $array1 out of $array2? Sorry if this is confusing, i'll be happy to go into details if needed. Hello
So I want to try and match everything preceding a file extension in a string using preg_match.
An example file name: "Images_home_blah.blah.jpg" .
I've tried the following regex:
/^([a-z0-9_\-\.]+)(?!\.jpg)/iBut this sadly appears to capture the whole string instead of ignoring the '.jpg' part. Can anyone point me in the right direction? Thanks, Drongo I have a list of companies I have to look up information for on the entity search page for the state. here is what i have so far except there seems to be a verification error. Anyone know how to fix this so the page will display results? <?php // INIT CURL $ch = curl_init(); // SET URL FOR THE POST FORM LOGIN curl_setopt($ch, CURLOPT_URL, 'http://appext9.dos.state.ny.us/corp_public/CORPSEARCH.SELECT_ENTITY'); // ENABLE HTTP POST curl_setopt ($ch, CURLOPT_POST, 1); //set curl options curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.

I know its done with preg_replace. Here is the string: Code: [Select] Header 1 <|header 2|> header 3 <b>header 4</b> I would like to get ONLY <|header 2|> from the above string. But "header 2" is variable so please its useless if the preg_replace isn't flexible to find whatever word is in there regardless. Thanks you. In the below example, we match 0 or more alphanumeric characters in the beginning and 0 or more alphanumeric characters in the end. Then we create 4 groups. Each group has "?=" which means "the next text must be like this". Now in first group we match any character 8 or more times. The next group we match 0 or more characters and a digit. In the next group we match 0 or more characters and a lowercase letter. In the next group we match 0 or more characters and an uppercase letter.
<?php
$password = "Fyfjk34sdfjfsjq7";
if (preg_match("/^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$/", $password)) {
echo "Your passwords is strong.";
} else {
echo "Your password is weak.";
}
?>
My question is do these four groups impact each other? That is, the fact that the first group has 8 or more characters means that all the groups must have 8 or more characters. The fact that the second group has a digit means that all the groups must have a digit. Or do they work exclusively meaning that a 4 character word with a single digit would match this pattern, even though first group says it must have 8 characters.
What I'm trying to do is have it match up the image file name wiht the same name as the link. Sometimes it does but sometimes obviously the image is random. Any ideas? Code: [Select] function spotlight($dbc){ $query = " SELECT * FROM characters WHERE characters.statusID = 1 AND characters.styleID = 1 ORDER BY RAND() LIMIT 1"; $result = mysqli_query($dbc, $query); $row = mysqli_fetch_array($result); $shortName = $row[ 'shortName' ]; $labels = array('shortName'); $img = array(); if($handle = opendir('images/spotlight/')) { $count = 0; while (false !== ($file = readdir($handle))) { if(strlen($file) > 2){ $img[$count] = $file; $count++; } } } echo "<a href='bio.php?shortName=" . $shortName . "'><img src='/images/spotlight/".$img[rand(0, (count($img)-1))]."' alt=Spotlight border=0 /></a>"; }
I wish to find the closest two DateTimes which are within $fillStart and $fillEnd and have the same week and 24 hour times as $gapStart and $gapEnd. For instance, the following results in $fillStartModified and $fillEndModified which meets that criteria. fillStart 2019-07-23 00:15:00 Tue fillEnd 2019-09-23 13:00:00 Mon gapStart 2019-05-23 00:15:00 Thu gapEnd 2019-06-23 13:00:00 Sun fillStartModified 2019-07-25 00:15:00 Thu fillEndModified 2019-08-25 13:00:00 Sun I came up with the following which seems to work, but it is kind of complicated and I am not positive it will meet all edge conditions. Any recommendations? Thanks
function getFill(\DateTimeImmutable $fillStart, \DateTimeImmutable $fillEnd, \DateTimeInterface $gapStart, \DateTimeInterface $gapEnd)
{
//$gapInterval = $gapStart->diff($gapEnd); // Doesn't work
$gapInterval = new \DateInterval('PT'.($gapEnd->getTimestamp() - $gapStart->getTimestamp()).'S');
if($gapStart > $fillStart) {
//The fill is older than the gap so make the fill's endTime match the gap's endTime
$fillEndModified = $fillEnd
->modify('previous '.$gapEnd->format('D'))
->setTime(...explode('.', $gapEnd->format('H.i.s.u')));

Hello group. I need some help with my code.
<?php
$a1 = array("line1"=>"1-2-3-10-14","line2"=>"1-2-3-10-34","line3"=>"1-2-7-16-35","line4"=>"1-2-3-17-19","line5"=>"2-5-11-15-32");
$result = array_intersect($a1,$a2); ?> Right now, I can only search and find an exact match of all 5-Numbers. I want to code a PHP form that will take a (5-number string) as input and then compare that string against an array database of (5-number strings) to find all matching number occurrences for each “LINE 1 thru LINE 5”. For instance, if I were to type the 5-number string “1-2-3-10-34” as input. The Output populated results would look like this .. Edited February 21, 2019 by Jayfromsandiego Hi there im just trying to understand how to compare and output results in a table. For example lets say i have the following table: Beans ID Type Location And say 3 records: 1 Baked kitchen 2 Runners Garage 3 Broad Kitchen I want to select only the beans that have matching locations and output the Type: Baked, Broad. I'm trying to get my head around how to work this out, if you could nudge me in the right direction that would be excellent. Thank you. I am trying to identify the username from a series of windows logs. I have been using (?:User Name:|Account Name:)\s*([\S]+) and it works for examples 1-4, however I'm having problems with example 5. Because it has two occurrences of the pattern Account Name: in the string I can only get the regex to return the first match, i.e. USER-PC$. How can I tell regex, that if there are two Account Name: patterns in the string, or the string contains the pattern "New Logon:" then return the second Account Name: match, i.e. John.Doe? eg 1 - The screen saver was invoked. Subject: Security ID: S-X-X Account Name: John.Doe Account Domain: INTERNAL Logon ID: 0xa4091 Session ID: 1 eg 2 - User initiated logoff: Subject: Security ID: S-X-X Account Name: John.Doe Account Domain: INTERNAL Logon ID: 0x3d95c This event is generated when a logoff is initiated. No further user-initiated activity can occur. This event can be interpreted as a logoff event. eg 3 - User Logoff: User Name: John.Doe Domain: INTERNAL Logon ID: (0x0,0x458E4AB4) Logon Type: 8 eg 4 - Successful Network Logon: User Name: John.Doe Domain: INTERNAL Logon ID: (0x0,0x43) Logon Type: 8 Logon Process: Advapi Authentication Package: Negotiate Workstation Name: USER-PC Logon GUID: {2e483a4f-} Caller User Name: USER-PC $ Caller Domain: INTERNAL Caller Logon ID: (0x0,0x7) Caller Process ID: 4816 Transited Services: - Source Network Address: xx.xxx.xx.x Source Port: 35029 eg 5 - An account was successfully logged on.
