PHP - Looking For A String Within Some Text And Wrapping It With A Link
I am trying to wrap a string with an anchor tag if it finds a match with a block of text. Here is an example text block: CONOCO 1'10x8 VC DF TP SGN||PRINCIPAL ILLUMINATION||ENG: CO3028TP_0VPR||DWG: CO200428||TO BE: DYED DIESEL (SPEC)|| The string I would want to wrap with a link would be "CO200428". The next problem is the drawings (what I'm searching the text for) has over 115,000 possibilities. The text blocks to search are over 1300. I have the drawing names stored in a simple mysql table...but doing a foreach takes forever...I imagine it will take even longer when looking in the text blocks... Is there a way to easily to do the anchor wrap? I don't know regex very well... Similar TutorialsHi I'm creating a program that creates an image from an input using imagettftext(). Is there a way I can force a new line if the text exceeds the permitted image width? Thanks in advance Ste I am looking for a dynamic image script that handles word wrapping and possible font resizing. Basically, I have a dimensions, a font and a company name. So, lets say I am trying to make a 300x300 image for Bob's Boats in verdana. I want a script that not only creates the image, but tries to use up the available space (putting each word on a line, using a large font, horizontally and vertically aligning everything) Worst case I'll write my own, but the algorithm seems pretty complex. For example, lets say the companies name was: Chocolates in a Basket, it could be: Chocolates in a Basket Or: Chocolates in a Basket But never: Chocolates in a Basket Worst case, I might make it so that it supports 3 lines, but only ever puts the company name on 2 by default, and if the user wants to manually change it, they can. Even that isn't perfect though, because if the dimensions are something like 300x35, you wouldn't want a second line, let alone a 3rd. Hi Support, I have a form, where it collects user description input. I can collect the inputs and store it with newline. The issue is - how to collect the http link to actual hyperlink ref during display. The following is my code: <textarea name="description" cols="50" rows="10" id="description"><?php echo str_replace("<br>", "\n", $description);?></textarea></td> For example, User input: Hi, Check it out - http://www.google.com/ I would like to display google link as href so that Viewers can click the link and go to the page. Right now, it is not href and user need to copy the link to new tabs or pages and then it can come. Thanks for your help. Regards, Ahsan I have been becoming more and more familiar with PHP over the past few months, but this problem stumps me. How can I take a string of words separated by spaces taken from an XML feed (example: word1 word2 word3 word4) and turn it into something like this: <a href="word1">word1</a> <a href="word2">word2</a> ... and so on. This has to be done on the fly, since it is taking the words from the XML feed, they change depending on the page. I want them to be in a vertical column, and be able to link each one to the search page for that word, so each link has to be different. An even more in-depth problem, how can I sort it then so that there are multiple columns if necessary, say one page only has 3 words, but another has 50. How can I split them up into multiple vertical columns, say with 10 words in each? Have I confused anyone yet? Hello, Any help would be great. I'm filtering and rss feed and to create a new feed with some <item>'s removed. Here is a snippet from the source file. <item> <title><h1>Indians, Pacers and Colts attendance is only part of story</h1></title> <link>http://www.newsweek.com/the-score/2010/07/29/indians-pacers-and-colts-draw-similar-sized-crowds/PARAMS/post/21385</link> <description></description> </item> <item> <title><h1>Declining attendance forcing Speedway to make changes</h1></title> <link>http://www.newsweek.com/declining-attendance-forcing-speedway-to-make-changes/PARAMS/article/21369</link> <description></description> </item> <item> <title><h1>Three issues that could derail Indy's 2012 Super Bowl</h1></title> <link>http://www.newsweek.com/the-score/2010/07/27/three-issues-that-could-derail-indys-2012-super-bowl/PARAMS/post/21341</link> <description></description> </item> I'm wanting to use the link tag to detect the item that need to be removed for the new rss feed. All <item>with <link> that contain http://www.newsweek.com/the-score/ as the beginning of the link need to be filtered out. Here is my code so far. <?php echo '<?xml version="1.0" encoding="UTF-8"?> <rss version="2.0" xmlns:media = "http://search.yahoo.com/mrss"> <channel> <title>CLE Calendar</title> <description>CLE Calendar</description> <language>en-us</language> <pubDate>June 14, 2010</pubDate> <lastBuildDate>June 14, 2010</lastBuildDate> <ttl>15</ttl>'; ?> <?php $rss = new SimpleXMLElement('http://www.newsweek.com/mobile-app/rss/feed?rssId=18&premium=false', null, true); ?> <?php foreach ($rss->channel->item as $items): ?> <item> <title><?php echo '<h1>' . $items->title . '</h1>'; ?></title> <link><?php echo $items->link; ?></link> </item> <?php endforeach; ?> </channel> </rss> Thanks in advance, MK Hi.. I am relatively new. I am trying to show an image link in my code below: $image = "<img src=<imgpg/" . $part_no . ".JPG />"; <td class = "guide_body" width = "66%"></td><td align = "center"><?php echo $image;?> There is more code but these are the problem lines I believe. Both are within the php environment.
This is producing:
It is supposed to look like this: So it is adding %3C for some reason between localhost and imgpg directory. I have no idea why this is happening. Is there something I can do to prevent this from happening? Or is there something I can do to erase the extra characters. (I'm not sure if they might be different though at some point. I have the same problem both on my local computer and the remote server.) Thanks very much for any help!! I have a line like this it prints text link but I prefer image link how should i edit it I would appreciate some feedback Code: [Select] $templates['etiket'] = array('name' => t('ETİKET'), 'module' => 'uc_invoice_pdf', 'path' => $templates_uc_invoice_pdf_path, 'pdf_settings' => $pdf_settings); Hi all just a bit like twitter i have a message system where when one recieves a mail i want there username to be like @user in blue but when sending a message the @user is in the message itself along with the actual message itsself, so i am trying to get the @ and everything after it so i can then change its color, can anyone help with this? 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 do want to validate a password input field to only allow numbers and letters without special character and spaces, and I also do want the same for the name input field. Since the old fashioned ways are deprecated. How would one approach to solve this issue the new way? I have the following variable: $text = "javascript:openimage('http://images.icecat.biz/img/norm/high/5966342-254.jpg',850,850)" Now I want to put the string "http://images.icecat.biz/img/norm/high/5966342-254.jpg" into a variable called $url ( $url = "http://images.icecat.biz/img/norm/high/5966342-254.jpg" ) How do I do this? Hey, I need a simple bit of code to do the following: I am trying to strip out a username in a string. This string will distinguish the username because the string will contain a * right before the username. For example: $string = "blah blah *username blah blah blah" The username can only contain numbers and letters. no spaces. And from that string all I want is the username, for example: $string = username (which will vary of course) Hope this makes sense, made it as clear as I possibly could. Thanks ahead! Hi, I am trying to take a string from a database and replace everything within {} with code... similar to how posting in a forum works. so say I have "...Lorem ipsom {gallery:1} sit imet..." it will take that string (from a DB) and replace "{gallery:1}" with "<?php gallery('1'); ?>". How can this be done? Or is there keywords I can search on to find the answer? Thank you in advance. Hello, Okay for some reason i cannot do this, when i open a file in php and search for string, it doesn't seem to work, some codes i tried: Code: [Select] $filename = 'example.txt'; $searchfor = 'hello'; $fh = fopen($filename, 'r'); $olddata = fread($fh, filesize($filename)); if(strpos($olddata, $searchfor)) { //fount it } else { //can't find it } fclose($fh); (above it just sample text, i was hoping you could give me sample code that will work) I tried many others like strstr, stristr, preg_replace etc etc, doesn't seem to find it.. this is my text file: Code: [Select] sdfsdfsdfsdfsdf[b]hello[/b]sdvsdf dfadfsdfsdfsddfsdf sdfsdfsdfs sdffffffffffffffffffffdv vsvdsdsf I don't want to find it by line, i want to simply open the text file and find the string.. thanks.. The table in the script has a set max-width. How can now a too long continuous text string as in "blaaaaaaaa", which also does not contain a space or dash, be broken, so the table does not become stretched to far? Which function is used for this? I wanted to replace a strings in a large text file .. what would be the fastest way ?! e.g the text file contains .. INSERT INTO `subjects` VALUES (1, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (2, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (3, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (4, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (5, 'some text here', 'some text here', 'some text here'); I wanted to replace the string " VALUES (1, " with "VALUES (" in each line .. I'm new in PHP so any response would be much appreciated .. thanks This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=342245.0 This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=327134.0 Hello, I am attempting to create a script where a user puts a text string into a form and clicking on submit. Then it adds that text string to a mysql database and gives the user a link back to it. Something like mysite.com/key.php?id=4 and when going to that link it will display the text string from the database but printed in an image. I wrote something up but I cannot get it to work. I may be a little in over my head. Any help is appreciated.
The way I coded this all to work is the user inputs the information into index.php which givekey.php inserts that into the database. I have not yet figure out how to do this in one single step. After that I wanted it to navigate directly to key.php which would display the key and the link to that page with the ?key=XX attribute. getkey.php
<?php
require_once 'dbinfo.php';
// database connection
$id = $_GET['id'];
// do some validation here to ensure id is safe
$link = mysql_connect($servername, $username, $password);
if (!$link) {
die('Could not connect: ' . mysql_error());
}
@mysql_select_db($database) or die( "Unable to select database");
$sql = "SELECT ukey FROM keycode WHERE id=$id";
$result = mysql_query("$sql");
$row = mysql_fetch_assoc($result);
mysql_close($link);
header("Content-type: image/png");
echo $row['ukey'];
?>

I have this but of php i have been trying relentlessly to get working.. for over a month.
<?php
$abs="one two three four words";
$mT = "testing for matching words";
$words=explode(' ', $abs);
//$sf=($words);
if (preg_match($words, $mT))
{
echo "the url $mT contains a Word";
}
else
{
echo "the url $mT does Not contain a Word";
echo "$words[4]";
}
?>
You see, I get a responce only using the last line "$words[4]", (obviously, because I am pointing it the Matching word, (ie: with [4]) Edited June 9, 2020 by x1705 better description. |
