PHP - How To Check A String For Words In An Array
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 Similar TutorialsHello, 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 $full_string ? Thanks for your help! Dead simple, I know it is but I'm still a little newbie. I have this chat box, and I don't want people to be able to swear in it so I need help making a function where you call the string as an argument and it returns true if the string has any words from an array in it, Even if the word is walking and not just walk. If it's true I can replace the entire string with something else. Can someone tell me what functions I need? I prefer you didn't do it all for me I need to learn Thanks in advance! hello, i seem to be stuck again and this bug is difficult for me to solve.
if(isset($_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... $query = "SELECT hello, world FROM table... I have a web server which contains a public site and a private site. I want to be able to test for public or private using the page title and return the appropriate header which contains a different banner, css etc. Firstly - the syntax below seems to be incorrect because it doesnt work correctly. More importantly how do I add all the values to an array and than iterate through it to check for a matching page title? Code: [Select] public function publicSite() { if ($this->getTitle()== 'Home' || 'About Us'||'Registration' || 'Sitemap' || 'Contact Us' || 'Useful Links' || 'Feedback') { return true; } return false; } Then later on I would have: Code: [Select] if ($this->publicSite()) { require($ROOT.'interface/pages/publicheader.php'); } else { require($ROOT.'interface/pages/privateheader.php'); } Thanks heaps!

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. 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 =) <?php $title = "This is an example of a sentence in a paragraph"; $title_array = explode(" ", $title); $count = strlen($title_array[0]); ?> what i want to do is store the count for every characters of every word in the array using a loop e.g the count will be stored in a variable $chr_count then when i access the count for "This" it should be like this $chr_count[0]=4, $char_count[1]=2 etc. hi every1 im driveing crazy with this... i have a database with a field with descriptions of products named "DESCRIP" in the main page i have a text field where user write the words to search for i wanrt make an "SELECT * FROM models where descrip like xxx OR descrip like xxx... bla bla bla" i wrote this code but send me an error... waht can be wrong??? $word='"SELECT * FROM models WHERE descrip LIKE ' ."'"; $srched=$_POST['words']; $pieces = explode(" ", $srched); $all=count($pieces)-1; for($i=0;$i<=$all;$i ++) { $word = $pieces[$i] ."'"; if($i!=$all) { $word .= $word . ' OR descrip like ' . "'"; } else { $word .= $word .'"' . ";"; } } $colname=$word; mysql_select_db($database_zero1, $zero1); $query_srch = $colname; $buscar = mysql_query($query_srch, $zero1) or die(mysql_error()); $row_srch = mysql_fetch_assoc($srch); $totalRows_srch = mysql_num_rows($srch); tnx in advcd Say I have this array: Code: [Select] array( 0 => time 1 => time 2 => to 3 => to 4 => to 5 => fly ); and 2 variables - $occMin and $occMax as number of occurrences. If: Code: [Select] $occMin = 2; $occMax = 3; I want to produce sorted list with most occurrences at the top: Code: [Select] array( 0 => array('to', 3), 1 => array('time', 2) ); My face just melted at the thought of even beginning to tackle this. Is this somewhat possible? would it require a monster function or am I missing some native php functions which could lend a hand? Hey, I have an if statement that requires to check a $_POST to make sure its an integer not a string but cant remember how to do this. Anyone able to assits Thanks Hi, How can i check if a string is a multiple of 0.1 without anything being left over? like 1.6 = true, 1.46 = false Hello, I'm working on an error form, and I want to check if the user inserted a number into the name field, and if so return an error.
