PHP - How To Filter Out Certain Part Of Text
Hi,
I have spend a few day's trying to get my head around how to make this code work as I'm still quite new to PHP The code below so far matches all text from a webpage within the <h3></h3> tags as within them is a url I need. Then that URL within all those h3 tags I only need the text after the last slash of the link so I can put into a flash object and load the requested value. As shown below heres what I have: <html> <head> <title>Find SC Links</title> </head> <body> <?php /* Have a look at the url below within the tags I only need the last part of the url after the / from all the text string <h3><a href="/anyfolder/recording-1-week">link1</a></h3> so just need recording-1-week <h3><a href="/anyfolder/recording-2-week">link2</a></h3> so just need recording-2-week <h3><a href="/anyfolder/recording-3-week">link3</a></h3> so just need recording-3-week then echo them out within this below echo '<div class="bbvideo"><object height="81" width="550"><param name="movie" value="'.$text_string_after_last_slash.'"></param><param name="allowscriptaccess" value="always"></param><embed allowscriptaccess="always" height="81" src="http://player.soundcloud.com/player.swf?url='.$text_string_after_last_slash.'" type="application/x-shockwave-flash" width="550"></embed></object></div><p>'; */ $data = file_get_contents('http://soundcloud.com/dj-handsfree/'); preg_match_all ("/<h3>([^`]*?)<\/h3>/", $data, $matches); $content = $matches[1]; //echo $content; $total = count($content); for($i=0; $i<$total; $i++) { echo $content[$i]."<br />"; } ?> </body> </html> Any help on pointing me in the right direction on this one be much help spend to much of my little time on this one.. Similar TutorialsCode: [Select] <? $out = preg_replace('/^(.{701}[^.]*).*/i','$1.',$detrsltnewsrow[news_desc]); echo $out; ?> </td></tr><tr><td colspan="2" class="para" style="padding-left:10px;"> <?= substr(stripslashes(trim($detrsltnewsrow[news_desc])),701) ?> </td></tr> I have the above snippet.. The first php statement, basically grasp the first 701 characters with the closet next stop "." character and out puts it. then out puts the HTML tags I have a problem with the second statement. I want to output anything after what has been outputted by: Code: [Select] <? $out = preg_replace('/^(.{701}[^.]*).*/i','$1.',$detrsltnewsrow[news_desc]); echo $out; ?> So need the correct syntax for Code: [Select] <?= substr(stripslashes(trim($detrsltnewsrow[news_desc])),701) ?> Currently it breaks at exactly the 701 character, want it to continue from the sentence the first code ended in. I am in the middle of a project on my own website and want to add a filter on it, the results are displayed in a HTML table and are pulled in from a mysql database using php and want to add a text filter on the site. I want the filter to work by clicking on a status text link such as open, pending or closed and it filters the results that match that on the same page for that relevant text value. I was not sure if it's more a php question or if can be done with ajax/javascript
Hello, I am new to the php community Hello. After much searching I dont seem to be able to find anyone who has had this issue. I am writing a bounce handler. To get the bounced email of the original recipient I need to download the TEXT part of the bounced message. The original message contained INLINE Images. Many of the bounced messages are returned what appears to be the INLINE image embedded as text in the TEXT part of the email. This means I am having to download TEXT parts which are many MB in size when all i need is about the first 1Kb to get the email address and status code. Does anyone know if there is an IMAP parameter/command that I can tell it to only download the first NNN BYTES of the TEXT Part. I have seen this done using FOPEN to read messages. My query gets the results and orders by one of the fields. Once I get the MySQL results I would like to find the first entry that has a letter as the first character of the same field that the list was ordered by, then split the results in to two parts and swap them. So that the results that have a letter at the start of the same sorted field are as the begining and the results that have the numbers as the start at the end of the array. But also so that the array works the same way as the original results string, so i can use say $results['mysqlfield'] Hi All I have a script which imports values from a csv file created using excel. However there are several blank values within the file where the person creating it has used blank columns to create whitespace in the file. I have used array_filter to remove these from the array, however how do I remove the redundant keys and 'squash' everything together so it is nice and neat? eg import would be , ,id, , surname, ,firstname, ,DOB, , address, , which returns array after array_filter [1]-> id [3]->surname [5]->firstname [7]->DOB [9]->address I want to return as an array which would be Quote [0]-> id [1]->surname [2]->firstname [3]->DOB [4]->address Is there a function to do this or would I need to create a custom one? HI all, Yesterday i read quite alot about htmlentities() htmlspecialchars() mysql_real_escape_string But today i stumbled upon filter() (http://www.w3schools.com/php/php_filter.asp). Does anyone know if this is also a good way to sanitize and may even be an alternative for the other functions? OR is it something completly different? I am still a novice with this so please enlighten me : ) TY Hello Guys, I need some help here.. I want to implement a Bad word filter and not quite sure how to do it.. I am grabbing the following vars from the text fields $ad_title = filter_var($_POST['ad_title'], FILTER_SANITIZE_STRING,FILTER_FLAG_NO_ENCODE_QUOTES); $ad_body = filter_var($_POST['description'], FILTER_SANITIZE_STRING,FILTER_FLAG_NO_ENCODE_QUOTES); Then its inserted into the db. I would like to run it through this function first.. Code: [Select] FUNCTION BadWordFilter(&$text, $replace){ // fill this array with the bad words you want to filter and their replacements $bads = ARRAY ( ARRAY("butt","b***"), ARRAY("poop","p***"), ARRAY("crap","c***") ); IF($replace==1) { //we are replacing $remember = $text; FOR($i=0;$i<sizeof($bads);$i++) { //go through each bad word $text = EREGI_REPLACE($bads[$i][0],$bads[$i][1],$text); //replace it } IF($remember!=$text) RETURN 1; //if there are any changes, return 1 } ELSE { //we are just checking FOR($i=0;$i<sizeof($bads);$i++) { //go through each bad word IF(EREGI($bads[$i][0],$text)) RETURN 1; //if we find any, return 1 } } } // this will replace all bad words with their replacements. $any is 1 if it found any $any = BadWordFilter($wordsToFilter,1); I really would also like to query a table for any words that match and then use a replacement like [censored] Any help would be greatly appreciated! Code: [Select] SELECT * FROM table1,table2,table3,table4,table5 WHERE table1_f = table2_id AND table1_g = table3_id AND table4_p = table1_id AND table5 _m = table4_id ORDER BY RAND() LIMIT 1 Right, Now What I want to do, is have a filter form, which posts to the above, and if: $filter1 = ""; it wont be include in the above code $filter1 = "word"; then i want to include AND table3_n = '$filter1'; in the above code thanks in advance. Hi. I was hoping someone could tell me whether this is possible and if so how I could go about doing it preferably with a tutorial as im pretty new to programming. I have a database that will contain 100's of records. I want users to be able to select filter parameters on this data by both text and checkboxes with it automatically updating the results (hopefully without page reload). I managed this so far using this Jquery filter script: http://www.picnet.com.au/picnet-table-filter.html. As this will table will have so many rows however I think it would take ages to load so instead I would like to paginate the table but still allow filters applied to affect all records not just the ones displayed on the current page. Any ideas on how i could do this? Thanks in advance for your help. I have some text boxes for searching the students in database also i have a drop down box for selecting student with balance amount to be paid tell me how to filter or search the list of stuents Code: [Select] <select> <option value="">All </option> <option value="">Unpaid </option> <option value="">Paid </option> </select> hi all i just read an article at http://www.phpro.org/tutorials/PHP-Security.html about not trusting server variables like $_SERVER['PHP_SELF'] so they explain, it can't be trusted and so on, but when it comes to a real life example i have difficulty understandig what someone could do with it since i assume it only has effect at client side. they use a form and say that Code: [Select] <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> ... </form> They give as example that someone could do the following: add Code: [Select] <script>alert("XSS HERE");</script> But i don't see how that would have effect to anyone except for the one that inserts that. Could someone maybe explain this a little to me. Hey, I have a word filter which is dectecting strings that are only embedded in words. Which i don't want it to do. For example: If i want to filter "FR" and some one puts france - it flags it because france contains FR. How do i make it only look for "FR" on its own seperated from a word instead of it flagging nearly all words with the two letters together? Heres my filter: $text = 'testing'; //this should not return 1 // fill this array with the bad words you want to filter and their replacements $bads = array ("test"); foreach($bads as $key => $search_needle) { if(stristr($text, $search_needle) == TRUE) { return(1); break; } } I have a MySql table full of records. id owner car location on my page i have these results in a table i want to set a filter up so the table will only show cars from eg location England. at the minute its just set to show cars that owner has but i want a location filter any help Hi ! I have an 2d array like this: column 1 column 2 column 3 $data[0][0] $data[0][1] $data[0][2] $data[0][0] RDR -1.3 0.001 $data[1][0] RQR 0.4 0.01 $data[2][0] DDR 1 0.00004 and more... Now i need to filter this data. I only need the rows with column 3 < 0.01 AND column2 > 1 or column 2 < -1 . I have this, but it doesn't work: $teller = 0; for($i = 0; $aantal>$i; $i++) { if($data[$i][2]<=0.01) { $p[$teller][0] = $data[$i][0]; $p[$teller][1] = $data[$i][1]; $p[$teller][2] = $data[$i][2]; $teller++; } } $teller2 = 0; for($i = 0; $teller>$i; $i++) { if($p[$i][1] < -1 || $p[$i][1] > 1 ) { #als de p value kleiner is dan 0.01 dan alles kopieren in een nieuwe array $r[$teller2][0] = $p[$i][0]; $r[$teller2][1] = $p[$i][1]; $r[$teller2][2] = $p[$i][2]; $teller2++; } } Can you help me? Hello, I have a client with a "contact us" form who has recently been receiving a lot of spam emails from the form. I already have a session set in place so the form is only active one time. I am now creating a filter for the message to look for things like a url or bb style codes etc. What I've got seems to be working but would like your thoughts on maybe a better way of doing it or if you see something I may be missing. IF an offending text is detected the ip address is sent to me and I can block ip from the site. If the message passes it is sent to the client. This is the related code. Code: [Select] <?php $themessage=str_replace("\r",'<br>',$_POST['message']); $badwords=array("[", "url", "http", "link", ".com", ".net", ".org", ".biz", "<"); $o=0; foreach($badwords as $key2 => $value2){ $pos = strpos($themessage, $value2); if ($pos==0) { } else{ $o=$o+1; } } if ($o==0) { //compose and send email to client } else{ $useraddress=$_SERVER['REMOTE_ADDR']; //compose and send email to me containing offending address } ?> Hi there, I have one question about the function rand(), What if i want to have an number between 0 and 360 Without 90 to 180 so 91,92,93,94.....180 can't be the number how can i do that? btw, I know its possible through if,while,for and so on. But is there an other way to do this? so I'm running a query on a database to get address's $address = $row['address']; it returns "1234 Test St" I want to be able to sort all the records by the street name without the numbers How do I know if Filter extension is on with my webhost? Or does it always work with PHP5? If I cannot use it, can someone recommend a good regex to validate EMAIL addresses?? Thanks, Debbie |
