PHP - Explode Limit?
I am in need of a alimit on the explode() fucntion but reading through the php explode manual on php.net there doesn't seem to be one that is right for me.
Basically I'm making a command system for a php chat and it has a command called ban. I have code that find out if it is a command or a normal string, I also have code that starts to break up the command into segments that can be places in the database. I want to split up "ban user lengthID "Reason why you were banned"" using explode($string, " ") but I notice that that will also break up the "reason why you are banned". How do I get it to split up the command but NOT thereason why you were banned string? Confusing I know, Please ask any questions that would help me explain it better Thanks in advance! Similar TutorialsI'm curious, is there any reason to use array_pop($value) at all when you can explode(' ', $value, -1) ??? Besides being php version < version 5.1.0 compatible of course. If I explode a string well using a substring when I implode that substring is now missing. for example. Code: [Select] $exploded = explode("[MAC]",$data); $data = implode($exploded); Now [MAC] would be missing in the $data string. any way to get around this? Unless buffer overflows or breaking out of code to perform a new command are problems that have been solved.... I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP? Hi all, I posted a similar question before and got some of the way but still need a little help. I have a product database with a description column where there are strings broken into lines. I need to find a way to explode() by line break. Currently explode("/n") doesn't work - it only returns one array item. Can anyone help me out? Thanks! Hi, I have an array for prices : forfait="158|Group Session,95|Group half session,45|Private Course,90|zumba course" which is used in a dropdown list where it shows as Group Session (158$) Group half session (95$) etc... The prices need to be used as an 'amount' field on the gift certificate as the descriptions must show as a 'label' on the gift certificate. So, I need to ' explode ' both the prices and the descriptions separately. I can 'explode' de prices using $tmp_forfait=explode("|", $value) and I get 158 95 45 and 90 But, how do I get the descriptions separately, without the prices meaning I need to 'explode' the digits and '|' ... Anyone can help me with that cope please?

Ok so what I have is a list of 32,000 IDs in a separate file called 32kIDs.txt and it has a list of roughly 32,000 user IDs for facebook which look like 100000233850312;1521225383;100000282767638;1252335882;1804268242 They're all separated by a semi-colon. What I need this script to do is echo each and every ID on screen, echoing each ID on a new line. I have been using the explode function but having trouble with it since I'm very new to PHP and don't have much experience yet. Here is my current code: <?PHP $iFile = "32kIDs.txt"; $login = file($iFile, FILE_SKIP_EMPTY_LINES); if(!is_file($iFile)) echo "The 32k add list couldn't be found...".sleep(999999); foreach($login as $line_num => $line) { $login = explode(" ", htmlspecialchars(str_replace(";"," ",$line))); echo $login[0]."\n"; } sleep(20); ?> So I bet there are going to be things in there that I don't even need and thing's I'm missing, if anyone can help it would be much appreciated. And I'd like to keep the code short, I could just put in: echo $login[0]."\n"; echo $login[1]."\n"; echo $login[2]."\n"; echo $login[3]."\n"; all the way up to echo $login[32246]."\n"; but yeah I don't like the thought of a 32k+ line script. Anyways... I have a script that connects to another server to pull data... When it pulls the data it comes back in the following format: Code: [Select] t1.sh t2.sh t3.sh test.sh However using the code bellow does not separate it like it should, it should put one file per line but I think I did something wrong... Code: [Select] // Pulls the output from the server: $var_test = $ssh->exec('./test.sh'); // Explodes it... $var_test2 = explode(" ", $var_test); // Echos it one per line... foreach ($var_test2 as $variable) { echo '<br>'.$variable; } Hi, I have a database that is going to contain recepies and ingredients tables. The recipe table is going to store the ingredients like this: 1,5,6,8 This refers to the table ingredients id. I now want to explode these vaules and count them up so they can be outputted like this: sugar (2) honey(1) flour (3) I have no idea of how to count all of the exploded id's and ouput them like above how to take a word in php or explode based on luas Bangunan :xxx For example I have string $string =" Kondisi Properti : Bagus Dilengkapi Perabotan : Unfurnished Sertifikat : Lainnya Daya Listrik : 2200 Watt Kamar Tidur : 3/1 Kamar Mandi : 2/1 Luas Bangunan : 92 m² Luas Tanah : 126 m² Jumlah Lantai : - Kondisi Properti : Bagus Sekali Dilengkapi Perabotan : Unfurnished Sertifikat : SHM - Sertifikat Hak Milik Daya Listrik : 6600 Watt Saluran Telepon : 1 Garasi : 3 Kamar Tidur : 4/1 Kamar Mandi : 3/1 Luas Bangunan : 300 m² Luas Tanah : 228 m² Jumlah Lantai : 2.5 "; eg I want to take every "Luas bangunan: xxx" Thanks I am having a nightmare with an explode and cant get it to work. I am posting a string using JQuery to a PHP form which needs to explode the string into an indexed array to be inserted into a database. This is what the string looks like "importance%5B101%5D=50&importance%5B100%5D=50&importance%5B99%5D=50&importance%5B98%5D=50" The original array has been serialised into the above string. The arrayname is importance. The array's index (inside the square brackets) is referenced from an ID from the page. The square brackets have been replaced by '%5B' and '%5D' and surround the array index by the JQuery. The value for each of these array items is shown as =50. So its basically the same as a GET when we have name=value&name1=value1etc') How would i explode the string above to remove the '%5B' and '%5D' to make the '[' and ']' reappear and then from then it can be read as a GET post? like 'name=value&name1=value1etc'. Using the new array of that index ready to be inserted into a MySQL database. Im going mad trying to solve this!!! hi, now i have something like this: $pizza = "piece1 piece2 piece3 piece4"; $one_word = explode(" ", $pizza); but i want to get 2 words together, like that: $two_words[0]='piece1 piece2'; $two_words[1]='piece3 piece4'; $two_words[2]='piece2 piece3'; $two_words[3]='piece1 piece4'; if it's impossible with explode, then it's fine if you use some other function, i don't care as long as it works. thank you, tastro With a database of synonyms, how do I compare a fragment of a texarea sentence split by the php explode function to return only five synonyms out of say 100 synonyms of the same word for each fragment.

Lets say I have a URL of http://mydomain.com/somename/ I need a function to grab USERNAME However I need it to work if someone uses http://www.mydomain.com/USERNAME/ OR With or without the trailing / after USERNAME I can't see to figure anything out which accounts for the many different variables that a person could type it. And yet another way is that the URL could be http://www.mydomain.com/USERNAME/SOME-CAT/SOME-POST/ Thanks Code: [Select] $newrating = round($imageinfo['rating'],2); this outputs: 4.49 in my db rating is 4.4884 all i need is the 4.... would i use some type of preg_replace or something just to grab the first 1 before the decimal? (all i need is the first number before the decimal) I store date data in MySql in this format DD-MM-YYYY , and now I need to explode this format when get information from database to get this: $day = DD , $month = MM , $year = YYYY. $result = $db->query("SELECT user_birthday FROM users WHERE user_id = " . mysql_real_escape_string($_SESSION['user_id']) . " LIMIT 1"); $row = mysql_fetch_assoc($result); $birthday = $row['user_birthday']; and I get this date format: 12-07-1980 How to explode this 3 values in day, month, year? Hi all! This is probably fairly simple for someone who is used to dealing with arrays. I have an array of data(Parsed from an XML document) containing a string I would like to further split into another array. The string is along the lines of: "<name>":<value>,"ID":20251,"ID2":2300,"ID3":2000 How can I split the above into: Array[<NAME>] => <VALUE> Notes: <name> changes often. depending on the query, it may have different <name> values. I have been trying to do it with preg_split and got to: Array ( => "<NAME>":<VALUE> [1] => "ID":20251) but I need to split it further at ":". I tried a foreach, but I failed miserably. Can anyone point me in the direction of better practice for arrays/preg_split? I have looked into the PHP documentation, but it is not enough for me. Thanks in advance I'm trying to add options to products. Currently, I have them in this format: Leather reinforced hilt,5.00::Stabbing tip,3.00::Logo,10.00 Code: [Select] $option_results = mysql_query("SELECT product_options FROM products WHERE product_id='".$product."'"); while($option_row = mysql_fetch_array($option_results)){ $option = explode("::", $option_row[0]); $option_part = explode(",", $option[0]); $option_part[0] = $option_name; $option_part[1] = $option_price; echo "<li><a href=\"#\">".$option_name.", Add $".$option_price."</a></li>"; } I would like the output to be: <li><a href="#">Leather reinforced hilt, Add $5.00</a></li> <li><a href="#">Stabbing tip, Add $3.00</a></li> <li><a href="#">Logo, Add $10.00</a></li> |
