However i would like the first paragraph to be converted into a header. string replacement will not work as it will replace all the p tags. i just want the 1st set of p tags to be replaced. can anyone help? thanks hi everyone, did not know what to make the subject, but here is what I want to do: I have a string, which gets returned to me from a linux app on my server, it looks something like this: Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <META HTTP-EQUIV="CONTENT-TYPE" CONTENT="text/html; charset=utf-8"> <TITLE> </TITLE> <META NAME="GENERATOR" CONTENT="OpenOffice.org 3.2 (Linux)"> <META NAME="AUTHOR" CONTENT="Administrator"> <META NAME="CREATED" CONTENT="20110106;14170000"> <META NAME="CHANGEDBY" CONTENT="HOD"> <META NAME="CHANGED" CONTENT="20110522;16540000"> <STYLE TYPE="text/css"> <!-- @page { margin: 0.26in } P { margin-bottom: 0.15in; direction: ltr; color: #000000; line-height: 0.15in; text-align: justify; widows: 2; orphans: 2 } P.western { font-family: "Arial", sans-serif; font-size: 10pt; so-language: en-US } P.cjk { font-family: "Batang", "바탕", serif; font-size: 10pt } P.ctl { font-family: "Times New Roman", serif; font-size: 10pt; so-language: ar-SA } A:link { color: #0000ff } --> </STYLE> </HEAD> <BODY LANG="en-US" TEXT="#000000" LINK="#0000ff" DIR="LTR" STYLE="border: 5.05pt double #000000; padding: 0.67in 0.92in"> <P>I want this and the tags around it, just not the html, head, body and their closing tags.</P> </BODY> </HTML> within the body, the tags are each styled for example: <p style="color: red"></p> so I cannot just get rid of all html, I want to get only all the content within the body tags, but without the body tags obviously strip_tags does not work as i need, I only want to strip certain tags. If someone can help me with this i will much appreciate it. I am asking out of curiosity, how does this problem usually get solved, when using a tag system to sort content, and users enter similar tags. For example: flower and flowers... which means the difference between singular and plural. Judging by other sites which are around, this problem is not solved at all, they simply let you add as many tags as you want and then rank the most used tags, it indeed is a solution, but seems more like a walk-around solution to me. Any ideas how somebody could approach to solve this one? EDIT: My suggestion would be an analysis function, which analyzes the entered tag and then suggests the user that similar tags have been already entered and perhaps he wants to choose one of those which have been already entered. This does work though with a high traffic websites what can happen is the following: php and php5 You can end up with two similar tags which are both widely used though have different meanings to the user base. This one could be solved by simply prohibiting similar tags with little additions or changes, and so to speak "forcing" the user to choose something which is already there. May be a way, though it can turn out as a bad solution as well. Do anyone know how i can put the html tags in the same line as the other html tags? Here's an example: Code: [Select] Images | Link | Delete | Enabled On my code, it break the tags to the new line without put on the same line as the other tags. Here's the code: Code: [Select] [code]<?php session_start(); define('DB_HOST', 'localhost'); define('DB_USER', 'myusername'); define('DB_PASSWORD', 'mypass'); define('DB_DATABASE', 'mydbtable'); $errmsg_arr = array(); $errflag = false; $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } function clean($var){ return mysql_real_escape_string(strip_tags($var)); } $username = clean($_GET['user']); $password = clean($_GET['pass']); if($username == '') { $errmsg_arr[] = 'username ID missing'; $errflag = true; } if($password == '') { $errmsg_arr[] = 'PASSWORD ID missing'; $errflag = true; } if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; echo implode('<br />',$errmsg_arr); } else { $qry="SELECT * FROM members WHERE username='$username' AND passwd='$password'"; $result=mysql_query($qry) or die('Error:<br />' . $qry . '<br />' . mysql_error()); if(mysql_num_rows($result) > 0) { $qrytable1="SELECT images, id, public FROM members WHERE username='$username'"; $result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error()); while ($row = mysql_fetch_array($result1)) { echo '<p id="images"> <a href="images.php?id='.$row['id'].'">Images</a></td> | <a href="http://' . $row["links"] . '">Link</a> </td> | <a href="delete.php?id='.$row['id'].'">Delete</a> </td> | <p> <p id="test">'.$row['Public'].'</td>''; } } } ?>[/code] Say I have the following text stored in a MySQL database... Code: [Select] <b>Classic Quote from movie</b> and I retrieve it into a variable called $text, how do I properly echo that so that it keeps the bold tags and actually display the text "Classic quote from movie" in BOLD? I'm doing something wrong somewhere along the line (simply doing "echo $text;") because it displays on the page as... Code: [Select] <b>Classic Quote from movie</b> Instead of... Classic Quote from movie Any info on properly storing and echoing back HTML would be very appreciated. Please help. I am trying to replace parenthesises () in a string with <>. I tried preg_replace and str_replace, but was not success. Here is what I have for str_replace: $word = "(test)"; $word = str_replace('(', '<', $word); $word = str_replace(array('(', ')'), array('<','>'), $word); How come this is not replacing correctly? $rp = strtr($rp,"[TIMES]","<span style='font-family: Times New Roman, Times, serif'>") Hey guys, I have a quick question. Im going to be making a script that will output the name of a news article along with the poster's name beside it. There is only a certain amount of space where that stuff can go so I want to know how I can make it so that say after 20 characters, it ends and puts "..." beside it. Is this possible with php? How would I do it? Hello, Is str_replace the best way to go about this? In MYSQL, a html template is stored, such that: Quote <table width="{$width}">lots of other ........</table> This is extract from the database, and stored in a string. I would use eval(), but, any user can update this template, so I need to be able to set which variables will be replaced with what the variable is. Thanks! Hey all, i need a function or a way to replace each letter in a string to a star (*) Thanks Hi first post here and very new to php. I built a form so that a data entry perosn can "build" new pages for our companies website. I pretty much have the basics of the form and the action page coded correctly, however my issue is that I need this final page where the form inputs are posted too to be an html document. I read some about the str_replace() function, but I'm not understanding how I could use that to replace the file extension of a page. Maybe I'm going about this all wrong. I also read that one can edit the htaccess folder to allow an html file to run php script. Not sure which way would be the best. One thing to mention though, is this application would be run locally to our back up files which is then scheduled to be uploaded to the remote server very night. Any help or suggestions would be greatly appreciated. Hi, I have 2 arrays, named $old_teams1 and $old_teams2. The arrays have from 6 values upwards. If $old_teams1 looks like this: Code: [Select] Array ( [0] => 3 [1] => 4 [2] => 3 [3] => 4 [4] => 1 [5] => 2 ) and $old_teams2 is the has the same mixture of values from 1-4..... .. How do I create a loop that will change all values of $old_teams1 and $old_teams2 to new values such as, 1->3, 2->4, 3->1, 4->2.... (The new values have been randomly generated). I have phrases in a string with the structure of "Note: some description" I want to replace "Note with (, but how can I replace the second " with )? Hello, I have been trying to replace a variable's value inside a function in case it matches a certain criteria but I can't seem to get it right. Let me give an example: Code: [Select] <?php function replace_value($obj) { if($obj==1) { $obj=2; } } $number = 1; replace_value($number); echo $number; So how do I go about making $number = 2, because it still has a value of 1 even after I pas it through the function replace_value. Hi I wonder if anyone will be kind enough to help. I am getting into forking with pcntl_fork() I intend to create a script that runs 24/7 running 100 forks/children/'threads' simultaneously. Once a child has finished it's task and exited how can I start a new child to replace it? I need some kind of infinite loop that can continually check for exited children and set up new ones. I'm finding it hard to get my head round since I'm new to forking. Can anyone suggest a way to do this? Thanks in advance. //$x = ereg_replace('[-a-z0-9!#$%&\'*+/=?^_`{|}~]+@([.]?[a-zA-Z0-9_/-])*','<a href=\'mailto:\\0\' '.$style.'>\\0</a>',$x); If this were an example post in a forum: Code: [Select] $post = '[quote author=james]hello this is a quote[/quote] here is some mor text between the next coming quote [quote author=david]hello this is another quote[/quote]'; What is the best way to replace the [quotes author=x] with opening html tag eg: Code: [Select] <div class="quote"><div class="quoteTitle">author=x</div> And then determine if the next is a [/quote ] is an opener or close quote? And then of course there is the issue of the user deleting a [/quote] or even placing a [/quote] before an open quote... Does anyone know of an example to look at? I want to be able to replace, let's say, every fifth letter from a string. The string is unknown, though, it could come from database, or a POST form. So I'm unsure if I could use str_replace. I think I may need to use preg_replace(), but I'm not not sure. Ok mixing javascript with php.... im having bugs . I basically want to replace any broken image links with a picture "noimage.gif" in the images folder. I tried this code but am getting the error: Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/wormste1/public_html/tilburywebdesign/shop/FTPServers/barryottley/showroom.php on line 78 This is the javascript header - all seems fine: <script language="JavaScript" type="text/javascript"> function ImgError(source){ source.src = "/images/noimage.gif"; source.onerror = ""; return true; } </script> this is the code thats erroring... is it the way ive written in the code into the IMG tag? while($row = mysql_fetch_array($result)){ echo "<TABLE CELLPADDING=0 CELLSPACING=0 WIDTH=100% BORDER=0>"; echo "<TR />"; echo "<TD WIDTH=30% VALIGN=TOP />"; echo " <A HREF='images/".$row['photo']."' target=_blank><IMG SRC='images/".$row['photo']."' width=186 height=155 border=0 onerror="ImgError(this);" /></A> "; echo "<br />"; echo "</TD>"; echo "<TD WIDTH=10 VALIGN=TOP />"; |
