PHP - Moved: Cleaning A String And Extracting Only First And Last Two Words In New String
This topic has been moved to PHP Regex.
http://www.phpfreaks.com/forums/index.php?topic=326004.0 Similar TutorialsHi there I allow users to make new albums. For each album they give a full display name, eg "New Years Eve 2012 at Persons' place", and a shorter display eg "New Years Eve 2012". The first string should be stored in a db and should be shown exactly as it is, so for that string I have: Code: [Select] <?php //$fullname gets stored in the db $fullname = myql_real_escape_string(htmlentities($fullname)); //when pulled from the db, it is only echoed, nothing else: echo $fullname; ?> Now I presume it is safe so far. Now is the 'tricky' part. Currently this is what I do to the short name: Code: [Select] <?php //$shortname gets stored in the database $shortname = mysql_real_escape_string(urlncode(str_replace(' ','',strtolower($shortname)))); ?> Now from this shortname, before the mysql_real_escape_string(), it makes a directory with that name. Now what happens is, if there are special charcters like '@', the '@' changes into '%40'. So the directory would be eg 'fun%40myplace'. The directories get made without a problem, but for some reason my uploader won't upload to this directory. It isn't the uploaders fault because in folders without these special characters there is no problem with uploading. Any ideas on how to fix this, or what the best method is to clean a string for url/directory names? hey guys i need to extract all the IP's of a string and loop them for more operations but for some reason i only get the first one <?php $string = '80.37.14.13 80.37.14.14 80.37.14.15'; preg_match("/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/", $string, $matches); foreach ($matches as $ip){ echo "$ip<br>"; } ?> The string is not really seperated by spaces ... it can actualy be messy and have ips rapped arround a lot of code. The regex works because i do get the first one ... What did i miss? I have managed to get this to work but it seems like it is a very long and messy solution. I was wondering if anyone had an idea of how this can be done better. I am new to php and don't know a lot. It shows the text between the tags <h1> and </h1> from the content of a different file Basically I had to start the substr() from the fourth position so it would actually skip the "<h1>" being included, and because I started on the fourth postion I then had to finish four places back to skip the "</h1>" being included. Code: [Select] <?php $id = $_GET['id']; $homepage = file_get_contents("./".$id.".php"); $title = stristr($homepage,"<h1>"); $titlepos = strpos($homepage,"</h1>"); $endpos = $titlepos - 4; echo "Title " . substr($title,4,$endpos); ?> I have a string that looks like /index.php?g1=111&g2=222&g3=333. How can I obtain the value of g1 (i.e. 111)? It does not represent the current state of the server thus I cannot just use $_GET. It also is not necessarily the first item. The script below appears to work, however, http://php.net/manua...n.parse-url.php states This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid. It appears that my string is a URI and not a URL, but I might be wrong. How should this be accomplished
<?php
$str='/index.php?g1=111&g2=222&g3=333';
$array=parse_url($str);
parse_str($array['query'],$get);
echo("<p>{$get['g1']}</p>");
?>
so I'm working on this system which requires me to inject anime show names into a DB for an index. I get them in this form: [Kira-Fansub]_HIGHSCHOOL_OF_THE_DEAD_-_04_(BD_1920x1080_x264_AAC) [F0E73009].mkv I need to get it in this form: Highschool Of The Dead sometimes the words are space seperated. the main part is to extract the text in between the ] and ( and with that i mean [stuff]extract this(other stuff) and sometimes it looks like this: [stuff]extract[stuff] I have NO CLUE how to do this preg_match_all doesn't get me any further.. maybe in stages? I have a string Code: [Select] <p>Bollywood romcom: a pair of wouldbe suicides choose the same bridge at the same time.</p><p><a href="http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema">Vue Cinema</a> (<a href="http://www.myvue.com/cinemas/index.asp?SessionID=0D86903A19334C93A7491563A77862A3&cn=1&ln=1&ci=66" target="_blank">www.myvue.com/cinemas/index.asp?SessionID=0D86903A19334C93A7491563A77862A3&cn=1&ln=1&ci=66</a>), Ozone Leisure Park, Grenoble Road (next Kassam Stadium), Oxford OX4 4XP; Tel. 08712 240 240 (10p per min from BT).<br /> </p> Using php i want to extract Code: [Select] http://www.myvue.com/cinemas/index.asp?SessionID=0D86903A19334C93A7491563A77862A3&cn=1&ln=1&ci=66 from the <a> tag. I have already tried using <?php $pattern = "/<a href=\"([^\"]*)\">(.*)<\/a>/iU"; preg_match_all($pattern, $link, $matches); var_dump($matches); ?> The output I get is array 0 => array 0 => string '<a href="http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema">Vue Cinema</a>' (length=81) 1 => array 0 => string 'http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema' (length=56) 2 => array 0 => string 'Vue Cinema' (length=10) I can't seem to find a decent code function to search for "curse" words that i would deem inappropriate in an array. Count the number of instances the function finds a curse word and then if the number is greater than one halt the script. something like the following but not really.... Code: [Select] $words = array('ass','fuck','shit'); $string = 'Blah blah blah ass blah blah fuck blah blah shit!'; //code to count the instances of the curse words(3) if($instances > 0) { echo "no cursing please."; } ; any help on how to do this would be much appreciated! Hello again to all I would like to ask if how can i removed the first 3 words on this string? Quote Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Thanks. hi folks, i have a variable in which some common words are stored and another variable in which a sentence is stored. I want to remove the common words from the sentence> Is there any way of doing this in PHP? Code: [Select] <?php $common_words = "to, this, all, the, from"; $sentence = "I want to remove all the common words from this sentence"; ?>the final output should be: "I remove common words sentence." hi there - hello dear PHP-Friends, good evening! - i want to extract some data ouf of a large html-file. i have - a very very large amount of data: approx 5000 x the following line-sheme!: Quote 67003 Cato Bontjes Vice Versum House 1 28832 Achim 62042 Cato Bontjes Vice Versum House 2 28832 Achim 41798 Cato Bontjes Vice Versum House 3 37139 Adelebsen 40034 Cato Bontjes Vice Versum House 4 21365 Adendorf 46218 Cato Bontjes Vice Versum House 5 31855 Aerzen 42481Cato Bontjes Vice Versum House 6 21702 Ahlerstedt 49761 Cato Bontjes Vice Versum House 7 26197 Ahlhorn Question: how can i extract the first 5 first digits...!? I have allready some solutions here - i need a very very robuste solution diblertone1 What I'm trying to do is take two arrays and combine them using array_combine. After they are combined I want to take each key and value pair and use them in a string to build a MySQL query. See below for some pseudo-code =D <?php $fields = array('first_name', 'last_name'); //the fields that will be set with an UPDATE query. $newvals = array('Joe', 'Blow');//The values that will go into $fields $arr = array_combine($fields, $newvals);//Each value now has a key of the field it will update. /** This is where I want to return my SET string with something like 'SET ' . $arr['first_name'] ' = ' . $arr['first_name_value'] ', etc etc. */ There it is, I suppose. Are there any easier ways of doing what I'm trying to accomplish, that is, am I on the right track or just making things harder for myself? Both arrays will have dynamic values throughout my application, so I need to be able to get both each field and value for each query. Any links to some constructs, etc, etc? That's all I really need and I can post the solution when I've figured it out. I want to check if a string has any of words listed in array; Code: [Select] $array=array('word1', 'word2', 'word3'); $string="This is a sentence containing word2"; Now I want to make an 'if else' to check if the string contains any of the words listed in the array. Thanks Dead simple, I know it is but I'm still a little newbie. I have this chat box, and I don't want people to be able to swear in it so I need help making a function where you call the string as an argument and it returns true if the string has any words from an array in it, Even if the word is walking and not just walk. If it's true I can replace the entire string with something else. Can someone tell me what functions I need? I prefer you didn't do it all for me I need to learn Thanks in advance! Hello, I'm having trouble getting a piece of code to work and as a result right now i have bloated code on a simple task. Currently my code looks like this: Code: [Select] //convert responses into one string to check for spam $full_string = $name.' | '.$email.' | '.$message; //look for spam words if ( (stristr($full_string, 'test')) || (stristr($full_string, 'http')) || (stristr($full_string, 'www')) || (stristr($full_string, 'site')) || (stristr($full_string, 'fake')) || (stristr($full_string, 'viagra')) || (stristr($full_string, 'cialis')) || (stristr($full_string, 'asdf')) || (stristr($full_string, 'txt')) || (stristr($full_string, 'doc')) || (stristr($full_string, 'xls')) || (stristr($full_string, 'htm')) || (stristr($full_string, 'sale')) || (stristr($full_string, 'free')) ){ I would like to instead place all my 'spam' words in an array like this Code: [Select] $spam_array = array('test', 'viagra', cialis...etc If i had all my spam words in an array, how would i write an if statement to check if any of those words appeared in $full_string ? Thanks for your help! hello, i seem to be stuck again and this bug is difficult for me to solve.
if(isset($_POST['boards']))
$boards[] = $_POST['boards'];
$allboards = implode("",$boards[0]);
echo $allboards;
outputs (browser source)...hello world I have a combobox with the "multiple" property. when two items are selected, the combobox "name" property has an array that passes to the $_POST variable. what i would like is those two words to be displayed on the same line. I have tried rtrim($var, "\r\n") but that does nothing. the reason i need them on the same line is because i would change then to "hello, world" and then add them as a mysql query, for example... $query = "SELECT hello, world FROM table... I have a string in the form of "word1-word2-word3-word4-word5-word-6-word7", but I want to shorten it to 5 words only. Hello, I am EXTREMELY new to PHP, and coding in general. I have attempted to search for an answer to this already, but I'm not sure I'm using terminology that will lead me to an solution, as I haven't come up with much. I'm hoping that someone can provide some assistance, or at least point me in the right direction for some reading. What I am trying to do it search a string for a match to any of 12 words. I'm wondering if there is a smarter way to do this than coding 12 different lines, each one looking for a specific word. If you can point me in the right direction, then thank you very much =) Hi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago! Thanks, Nick |
