PHP - Limiting The String Length By The Number Of Words
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.
Similar Tutorialshello all - I have a social network for the cystic fibrosis community and we've had a spammer the passed couple of days. I have captchas set up and they work well, but in addition to those I want to limit the amount of blogs a user is allowed to post a day. I have been able to count and echo out the amount a user has made, but for some reason, when I use an if statement to stop the blog from posting it still post's. I have been working on this going on hour 8 now and need some major help Thanks in advnace. Here is my code Code: [Select] if(isset($_POST['subComposeBlog'])) { $query = "SELECT COUNT(`id`) FROM `cysticBlogs` WHERE `Author` = '".$auth."' && `date` = NOW() && `status` = 'active'"; $request = mysql_query($query,$connection) or die(mysql_error()); $result = mysql_fetch_array($request); $valid = true; if($_POST['Category'] == "null") { $valid = false; $error_msgs[] = "Whoops! Please select a category for this blog."; } if(empty($_POST['blogTitle'])) { $valid = false; $error_msgs[] = "Whoops! Cannot submit a blog without a title,how are you going to attract people's attention to read your masterpiece?"; } if(empty($_POST['blogBody'])) { $valid = false; $error_msgs[] = "Whoops! Cannot submit a blog without a body,that would not be a blog now would it?"; } if($result['COUNT(`id`)'] > 3) { $valid = false; echo "Whoops! You can only write three blogs per day due to spam"; } if($valid) { $query = "INSERT INTO `cysticBlogs` ( `blogTitle`, `blogBody`, `date`, `time`, `Author`, `Category` ) VALUES ( '" . mysql_real_escape_string($_POST['blogTitle']) ."', '" . mysql_real_escape_string($_POST['blogBody']) ."', '" . date("Y-m-d") ."', '" . date("G:i:s") ."', '" . $auth->id ."', '" . mysql_real_escape_string($_POST['Category']) ."')"; mysql_query($query, $connection) or die (mysql_error()); header("Location: BlogsSecurity.php"); } } This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=326004.0 I have a database of 100 lines which have echoed onto the page so each line within the database is printed. I would like to limit it to ten. However, I have tried a whole range of different loops but none of them seek to work. Some of them print the database ten times so I have 1000 lines on the page. Can anyone advise the best method of limiting how many lines within a database are printed on the page? This isn't for anything practical, I'm just fiddling. Anyways, I'm wondering if there's anyway to make this more efficient since at higher lengths it could become really heavy. $l is length of the number. function fixed_random($l) { $number = ""; do { $r = mt_rand(0, $l); $number .= $r; } while (strlen($number) < $l); return $number; } Hi all,
The output of the following line of code where user is Jack1234
$user = filter_input(INPUT_POST, 'user', FILTER_SANITIZE_STRING);using var_dump is string 'Jack1234' (length=8)I would like to know if there is someway we can use/retrieve the length value of the string that is displayed in the output or verify the string length against it. Thanks. Howdy, I have a page on my site that displays events I have uploaded. Below is the code that displays the event title. I want to know if there is a simple way to limit the characters of the title that a view will see. For example, limiting the title to 10 characters. So, if I had an event titled "My awesome new event". You would see "My awesome..." Hope this makes sense. I'm not sure if you will need to see more of the code to help me, thank you! <a href ="event-description.php?eid=<?php echo $data->EventId?>"<span class="events-title"><?php echo $data->EventTitle ?> <?php require_once('upper.php'); if(isset($_POST['submit'])) { //This is code in which we can choose the type and size file uploaded or upload anything. We can declare the path of folder or can do without it. if($_FILES['uploaded_file']['size']< 200000) { /*if($_FILES['uploaded_file']['error']>0) { echo "Error occurs".$_FILES['up_test']['error']."<br/>"; } else{*/ $Title=$_POST['Title']; $City=$_POST['City']; $Content=$_POST['Content']; $Date=$_POST['Date']; echo "Uploaded Title--$Title<br/>"; echo "Uploaded City--$City<br/>"; echo "Uploaded Content--$Content<br/>"; echo "Uploaded Date of Event--$Date<br/>"; /*if(file_exists("upload/". $_FILES['uploaded_file']['name'])) { echo "File".$_FILES['uploaded_file']['name']." already exists"; } else {*/ move_uploaded_file($_FILES['uploaded_file']['tmp_name'],"upload/".$_FILES['uploaded_file']['name']); echo "File uploaded-- ".$_FILES['uploaded_file']['name']."<br><br><br>"; } else{ echo "File size is too large or Not Uploaded "; } $path="upload/".$_FILES['uploaded_file']['name']; require_once('database.php'); $result=mysqli_query($dbc,"insert into events (Title,City,Content,Photo,Date) values ('$Title','$City','$Content','$path','$Date')") or die ('Not Connected Events'); //echo "PAth"; } ?> <html> <head> <link rel="stylesheet" type="text/css" href="css/style.css" /> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post" enctype="multipart/form-data"> <h4>Enter Events</h4><br> Enter Title <br><textarea rows="10" cols="10" name="Title"></textarea><br> Enter City <br><input type="text" name="City"><br> Enter Content <br><textarea rows="10" cols="10" name="Content"></textarea><br> <label for="file">Upload Photo<br></label> <input type="file" name="uploaded_file" /> <br /> Enter Date of Event<br> <input type="text" name="Date" value="yyyy-mm-dd"><br> <input type="submit" name="submit" value="Upload" /> </form> <?php require_once('lower.php');?> </body> </html> Hi friends...............

A way of comparing the words in one static array against other dynamically created arrays (created from mysql queries) 2. Work out how many similar words there are - then assign that number to that array My static array is...$comparewithme = array with values = this is an example of an array Mysql_query("select id, words from table_example") Results from query are put into an array that is named according to id.. $result2 = array with values = this is an example of queries $result3 = array with values = this is not an example of php Comparison should give the following info Comparing $comparewithme with $result2 should generate a hit rate of 5 (similar words=this is an example of)... Comparing $comparewithme with $result3 should generate a hit rate of 4 (similar words=this is an example)... Any ideas greatly appreciated...thanks in advance Hi all - I'm setting up a custom PHP blog. It pulls the data from a MySQL database which includes HTML tags (<p><div><span> etc...). I would like to display only up to 50 words per post on the blog page, which users can then read and click a link to then see the entire post. I've developed some code which does this, however, it seems to be stripping my HTML tags... Very sad! Would be very very grateful if one (or more) of you kind lot would have a look at my code and let me know if there is a easier (I'm all for easy) and proper way of implementing this so that it works without stripping my HTML tags. Cheers!!! Code: [Select] // Counts number of blog words in the content $blog_content_words = str_word_count($blog["content"], 1); // Sets the blog_words variable to 0 $blog_words = 0; // Prints title on page as a permalink to a post echo '<h1><a href="blog.php?id='.$blog["id"].'">'.$blog["title"].'</a></h1><p>'; // Loops while blog_word is under 50 while($blog_words < 50) { // Prints a word from blog_content_words array of blog post and adds a space afterwards echo $blog_content_words["$blog_words"]." "; // Adds 1 to the blog_words counter ++$blog_words; } // Adds a read more link to the post which links to full blog post echo '... <a href="blog.php?id='.$blog["id"].'">[read more]</a></p>'; 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." 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! Hi, how can I match two keywords in a string? eg. if keywords (Kids,Hoody) are in this string (Animal Kids Basic Hoody Blue) do something..... Thanks. 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.

Does such function exist? Hi, I have a Flash contact form that sends its name, e-mail, and message variables to a PHP script. The script works fine if the message is under ~700 characters, but anything more and the script won't post the message at all. An e-mail with just the name and e-mail address will come through to my inbox (which is embarrassing as a potential client sent me a contact form e-mail about a development job ). Is there some way to check the maximum character length for a string variable? Or to set its length to something higher? This is my php. Thank you!! <? $senderName = $_POST['userName']; $senderEmail = $_POST['userEmail']; $senderMessage = $_POST['userMsg']; $senderName = stripslashes($senderName); $senderMessage = stripslashes($senderMessage); $senderMessage = strip_tags($senderMessage, '<p><br>'); $to = "kevin@kevinburkeportfolio.com"; $from = "email@kevinburkeportfolio.com"; $subject = "E-mail from $senderName"; $message = "<p><font size='2.5' face='Helvetica Neue, Helvetica, Sans Serif'><b>FROM:</b> $senderName <br><br> <b>E-MAIL:</b> <a href='mailto:$senderEmail'>$senderEmail</a> <br><br> <b>MESSAGE:</b> $senderMessage</p>"; $headers = "From: $from\r\n"; $headers = "MIME-Version: 1.0\n"; $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; $to = "$to"; mail($to, $subject, $message, $headers); $my_msg = "Thanks $senderName, your message has been sent."; print "return_msg=$my_msg"; exit(); ?> 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! 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.
