PHP - Conditional Regex Matching
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. Subject: Security ID: S-X-X Account Name: USER-PC$ Account Domain: INTERNAL Logon ID: 0x3e7 Logon Type: 2 New Logon: Security ID: S-X-X Account Name: John.Doe Account Domain: INTERNAL Logon ID: 0xa4062 Logon GUID: {23-xx-22} Process Information: Process ID: 0x2fc Process Name: C:\Windows\System32\winlogon.exe Network Information: Workstation Name: USER-PC Source Network Address: xx.x.x.x Source Port: 0 Any help would be appreciated:) Similar TutorialsIn 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.
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? 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 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. Hey, I need a bit of help replacing some variables in a string. 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. 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.

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. 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 .

$result = array_intersect($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 I'm working a membership application page for my amateur radio club. I'm currently stumped passing a variable from HTML to PHP. The variable is called "nametag" and it's a "radio" type. No Matter if I select 10 or 0. I still get 15 being passed to PHP.
Any help is appreciated.

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('.', $gapEnd->format('H.i.s.u')));
if($fillEndModified->diff($fillEnd)->format('%a') >= 7) {
$fillEndModified = $fillEndModified->add(new \DateInterval('P7D'));
}
$fillStartModified = $fillEndModified->sub($gapInterval);
if($fillStartModified < $fillStart) {
$fillStartModified=null;
$fillEndModified=null;
}
}
else {
//The fill is newer than the gap so make the fill's startTime match the gap's startTime
$fillStartModified = $fillStart
->modify('next '.$gapStart->format('D'))
->setTime(...explode('.', $gapStart->format('H.i.s.u')));
if($fillStart->diff($fillStartModified)->format('%a') >= 7) {
$fillStartModified = $fillStartModified->sub(new \DateInterval('P7D'));
}
$fillEndModified = $fillStartModified->add($gapInterval);
if($fillEndModified > $fillEnd) {
$fillStartModified=null;
$fillEndModified=null;
}
}
return [$fillStartModified, $fillEndModified];

The problem is how do i approach an algorithm to do this in the first place. Cards are stored and structured by 2 characters seperated by a full stop. Example - 2 of diamonds and 3 of clubs is: D.2,C.3 now imagine a line of 5 cards (the river) and im trying to work out what they have and return the answer such as: 2 pairs or royal flush etc I so far decided my easiest way is to explode on the comma to get each card - then explode a second time on the full stop to get the suit and value into different variables. How ever - after that point im lost how i can do this up against the river to check what hand the user has. Any one got any tips on the best approach ? This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=311251.0 Say i have two arrays with custom keys.

Thanks in advance, samanj hi im testing out my site and basically when users register their passwords and encrypted for security obs however when i go to test the login with the exact same password as the one used to register the system detects it as invalid when its not, I've literally copy pasted the password so that i was sure it was the same therefore the issue is within the encryption does anyone have an idea how to overcome this I've tested changed names of variables but nothing seems to help I've even got an error reporting function but no error is detected
<?php
error_reporting(E_ALL);
include_once("conninfo2.php");
if(isset($_POST['username']) && trim($_POST['username']) != ""){
$username = strip_tags($_POST['username']);

$hmac = hash_hmac('sha512', $password, file_get_contents('textfiles/key.txt'));
$stmt1 = $db->prepare("SELECT usersid, password FROM login WHERE username=:username AND activated='1' LIMIT 1");
$stmt1->bindValue(':username',$username,PDO::PARAM_STR);
try{
$stmt1->execute();
$count = $stmt1->rowCount();
if($count > 0){
while($row = $stmt1->fetch(PDO::FETCH_ASSOC)){
$uid = $row['usersid'];
$hash = $row['password'];
