PHP - Set Variable And Compare In One Command
I typically only use the first two solutions. Is there anything wrong with the third? Is there any more streamlined way to do it?
function f1($x){return $x*1;} function f2($x){return $x*1;} $x=2;$y=1; if(f1($x)>f2($y)){echo(f2($y)."\n");} // or $f2_y=f2($y); if(f1($x)>$f2_y){echo($f2_y."\n");} // or if(f1($x)>$f2_y=f2($y)){echo($f2_y."\n");} Similar TutorialsI run an article directory. I was wondering how I could check an article that is currently pending review against published articles in our database. What I am looking to do is to place the content of the body in the pending article into a variable. That much is easy and I know how to do that. Then I would like to use that variable to compare against other content in our database and have it output a percentage of how close it is to any other article already published in our database. Any direction our guidance with this would be so greatly appreciated. Thanks! Hi again everyone, I am trying to compare a php variable to the value of a row in mysql, but keep getting the following error: Code: [Select] Wrong perameter count for mysql_result() What syntax would I use to accomplish this? Here is my code: // connects to server and selects database. include ("../includes/dbconnect.inc.php"); // table name $table_name = "availability"; // split up date into 3 separate fields $date = "12/25/2010"; $date_split = explode("/", $date); $month = $date_split[0]; $day = $date_split[1]; $year = $date_split[2]; // check if earth room is already reserved $taken = "Reserved"; $sql = "SELECT earth_room FROM $table_name WHERE month='$month' AND day='$day' AND year='$year' LIMIT 1"; $result = mysql_query($sql) or trigger_error("A mysql error has occurred!"); $row = mysql_result($result); if($row == $taken){ echo "Room Already Reserved"; } else{ echo "Room Available"; } Thanks for the help, kaiman I am trying to get a simple thing working. I have a domain with google that I want to change the point to IP when I access a PHP page. I have a DB table with settings that I am using for the username, password, etc. The issue is that the command to change the IP always sends the same IP. No matter what I try. I have tried assigning a fixed entry for the variable $localip, I have set that variable to 0 ahead of the query to get the info from the table. Nothing I do will change the variable in the command. I can manually put the command in a browser and it will perform the change. Can anyone comment on what I am missing here?
<?php ini_set("display_errors", 1); ini_set("track_errors", 1); ini_set("html_errors", 1); error_reporting(E_ALL); require('/var/www/html/cqadmin/utils/connect.php'); $sql = "SELECT * FROM `failover` LIMIT 0, 30"; $result = mysqli_query($link,$sql) or die(mysql_error()); $row = mysqli_fetch_array($result); $localip = ($row['localip']); $dnsusername = ($row['dnsusername']); $dnspassword = ($row['dnspassword']); $domain = ($row['failoverurl']); $location = ($row['location']); $dealer = ($row['dealer']); $output = shell_exec("curl -s https://$dnsusername:$dnspassword@domains.google.com/nic/update?hostname=$domain&myip=$localip"); mysqli_close($link); ?> I get no errors on the page and if I echo $output I get a nochng message back from Google
Thanks for looking!! Hi i dont know whether i've overlooked something but im finding it hard to answer this myself.. Background of the problem: Im keeping the contents of a page in a database, so each page would be a template, and the body text will be stored in the database. So if i want to call up the contents for my 'About' page, i would use the php command: "<?php getAboutPosts(); ?>" The code behind that will be: function getAboutPosts() { $query = mysql_query("SELECT * FROM posts WHERE id = '20' ") or die (mysql_error()); while($subm = mysql_fetch_assoc($query)) { echo "<h2>" . $subm['Title'] . " by iVisual Media" . "</h2>"; echo $subm['Content']; } } My Actual Problem The text does echo fine, but it is completely unstructured, I.E. it isn't paragraphed, i cant include any type of tag like <b> because it doesn't seem to echo them, although when i check PHPMyAdmin it has all the tags saved in with the content? Example: I have this saved in MySQL Database: <h4>We are a professional website and graphic design business in Basildon, Essex, providing online marketing strategies for companies throughout the UK.</h4> <p><br /> Whether you require a brochure website, blog or a full e-commerce solution, Imagine Design Studio can help. Maybe you have a new business and want to create an online presence or an established business looking to pull your company into the 21st century.</p> <p> But when it echos, i get this: We are a professional website and graphic design business in Basildon, Essex, providing online marketing strategies for companies throughout the UK. Whether you require a brochure website, blog or a full e-commerce solution, Imagine Design Studio can help. Maybe you have a new business and want to create an online presence or an established business looking to pull your company into the 21st century. Things i've tried: Adding a class to the DIV which the echo will go into - This works for colouring etc, but i still need to paragraph the text and use italics occasionally. Please help guys! Thanks in advance Hi, I want to compare the tables from 2 mysql databases in a table. This is what I have: for($i=0;$i<$maxCount;$i++) { echo "<tr>"; // start row //fist data square if ($i < count($db1)) echo "<td>{$db1[$i]}</td>"; else echo "<td></td>"; echo "<td></td>"; // middle //last if ($i < count($db2)) echo "<td>{$db2[$i]}</td>"; else echo "<td></td>"; echo "</tr>"; // end row } that will put make a nice table for me to see. What I'd like to do next is have all identical sql tables lined up. So for e.g I have 2 arrays of table names that will look like this: Databse 1 Database 2 table1 table1 table2 table3 table4 table4 does that make sense? Also is there a more elegant way of scripting what I have? Can php be used to get two blog entries and compare them side by side, with a choice one which one to use. A bit like wikipedia has ? Hi everyone! I've been looking for a solution, but i just can't find it anywhere... Ok, so the problem is: i have a database which looks something like this: user_id product_id score 14 . 235 . 79 23 . 235 . 32 53 . 665 . 21 14 . 235 . 90 5 . 675 . 45 This is step-by-step of what i need to do: 1. Select user - user_id =343 2. For user_id =343 select all products that he gave score to: product_id = 43 - score = 99 product_id = 12 - score = 56 product_id = 68 - score = 32 product_id = 124 - score = 67 3. Find all users that voted for the same products e.g.: for product_id = 43: user_id = 125 voted 93 points, user_id = 23 voted 56 points. 4. Calculate the difference between the score of user, so: for product_id = 43: user_id = 125 voted 93 points (99 - 93 =6 points of diff.) user_id = 23 voted 56 points (99 - 56 =43 points of diff.) return the results.... That's basically what i need to do. I still don't know the number of the users, or product, but it doesn't really matter - i just need to make it work. Ok, hope someone can help! Hi! I have a table called "Categories" Here is the structu id | Categories | ParentCategories 1 | Rings | Parent Category 2 | Pendants | Parent Category 3 | Ladies Rings | Rings 4 | Ladies Pendants | Rings 5 | Gents Rings | Gents 6 | Necklaces | Parent Category But Necklaces is one of those who is not going to have any subcategories or you can say, it is going to be a category by itself. So how can I construct a php statement to get data out of MySQL to determine that Necklaces is a Category which does not have subcategories. Please help ! Thank you ! - Xeirus.

I have this code that compares date times but im not sure if its correct. if("2008-08-10 00:00:00.0" > strtotime("now")) { echo "here"; } The code echo's here, but it shouldn't because the time is less than the current time. Any ideas? how to compare date with current date let say $date="2010-10-08 2:00 PM" how can i compare $date with current date and get the result in days, hours, minutes and seconds thanks Hi! What should the code be if I get an IP address to a postback url and I want to find that member in my database who has that IP-address? The postback comes like this http://yoursite.com/postback.php?ip=xxx Please help Hi, I am trying to write an SQL to XML converter, so so far I have all the records inputted into the db tables, and now I want to append a child, but I don't know how to compare current row's field value with the next row below it, specifically I want to check if a current row is parent of the next row. I have already got the XML to SQL function working (some bugs but for the most part it's working) So for eg: <?php $query=mysql_query("SELECT * FROM edge"); while($row=mysql_fetch_assoc($query) ) { if($row['target'] is parent of the next row), then append the next row as child of current row } ?> Table edge is one of the tables that hold target node/source(aka: parent) nodes. Any help much appreciated! I know the forum is supposed to be used to help with any code I have come up with but here's to taking a shot anyway: I am in need of creating a php script that will allow me to input two different XML files and upon pressing "go" will compare these two files and save only the differences to a new xml file. Thing is, I have no idea where to start. Are there any php functions that exist that I can use to do this? If not, cn someone help me create one? Would this be better handled in javascript? If so, how can I do so using a method similar to the above? Any kind of help would be greatly appreciated. I need to compare several arrays...to narrow down a bunch of mysql selects. I can't figure out which of the array_diff, array_unique, array_merge options there are. I need to get an array of umpires (baseball), then compare that to the array of umpires that can work a given level, then compare that to the array of umpires that can work at that school, and finally compare that to the array of umpires who have asked for the day off. In the code below, all of the selects work...the echo's that are commented out printed out what I expected them to. I'm having a problem with the array comparisons at the end of this code: Code: [Select] <?php //connect to database $dbc = mysql_pconnect($host, $username, $password); mysql_select_db($db,$dbc); //get info of game $sql = "SELECT sport,home,day FROM games WHERE `game_id` = $_GET[game]"; $rs = mysql_query($sql,$dbc); while($row = mysql_fetch_array($rs)) { $game_array = $row['sport']; $home_team_array = $row['home']; $game_day_array = $row['day']; } //list of all umpires in association $sql = "SELECT ump_id FROM ump_names WHERE '$_SESSION[association_id]' = `association_id`"; $rs = mysql_query($sql,$dbc); while($row = mysql_fetch_array($rs)) { $name_array[] = $row['ump_id']; // echo "<br /><br />All Ump ID's Array = "; // foreach($name_array as $name_array_final) { // echo $name_array_final . "<br />"; // } } //get bad schools list $sql = "SELECT ump_id FROM bad_school WHERE '$_SESSION[association_id]' = `association_id` AND `school` = '$home_team_array' and `sport` = '$game_array'"; $rs = mysql_query($sql,$dbc); while($row = mysql_fetch_array($rs)) { $bad_school_array[] = $row['ump_id']; // echo "<br /><br />Bad School Array = "; // foreach($bad_school_array as $bad_school_array_final) { // echo $bad_school_array_final .

What I want to do is: compare $official_level_array and $name_array...only keep those that are in $official_level_array. Then, compare that result with $bad_school_array...removing those in the $bad_school_array...and keeping the ones that are left. Then, compare that result, with $days_off_array...removing those in the $days_off_array...and keeping the ones that are left. Print out what's left... Where am I going wrong? Not sure if there is a better way to do this, but I want to check whether the value in a Sticky Field is the same as what is in the Database. If what is in the Sticky Field is *exactly* what is in the Database, then the User didn't update that field, and so I would NOT do an UPDATE. Seem reasonable? Here is where I grab the value out of the Form... Code: [Select] // **************************** // Process Each Form Field. * // **************************** foreach($_POST['answerArray'] as $questionID => $response){ // Copy trimmed Form array to PHP array. $answerArray[$questionID] = trim($response); And here is where I grab the existing value in the Database... Code: [Select] // ******************** // Check for Answer. * // ******************** // Build query. $q1 = "SELECT response FROM bio_answer WHERE member_id=? AND question_id=?"; // Prepare statement. $stmt1 = mysqli_prepare($dbc, $q1); // Bind variable to query. mysqli_stmt_bind_param($stmt1, 'ii', $memberID, $questionID); // Execute query. mysqli_stmt_execute($stmt1); // Store results. mysqli_stmt_store_result($stmt1); // Check # of Records Returned. if (mysqli_stmt_num_rows($stmt1)==1){ // Answer Found. // Bind result-set to variable. mysqli_stmt_bind_result($stmt1, $currResponse); // Fetch record. mysqli_stmt_fetch($stmt1); So I guess I want to compare $answerArray[$questionID] against $currResponse and see if there are any differences?! What is the best way to do that? Any better ideas of how to check to see if the User made any changes to a field so I only do an UPDATE if there was actually a change? Thanks, Debbie I have the time time now viewed as 17:11. The time $Start_Time is 17:00. The time $End_time is 18:00. Can I use this to check if time is in between starttime and endtime? Or do I have to convert it to other formats before it understand that I'm comparing it as times and not just numbers? if($Start_Time < $Now_time && End_Time > $Now_time){ } Hello. Assuming that I have two variables: $exURL=@$HTTP_REFERER; $goodURL = 'http://www.SomeSite/login/'; How can I check if the two URLs match each other? Regards Hello Guys, I am trying to figure this out.. I have a page that has several check boxes that when checked the values ends up as an array Like this 1, 3, 9, 6, That's what it looks like in the database. I want to compare the values (numbers) submitted with the values in my database table called benefits Here is the function I wrote this function and I want to check the values of the submitted values but I am just not sure how to compare the values, especially with a comma in the array. Code: [Select] $benefits2 = $_POST['benefits']; function check_benefits ($benefits2,$member_id,$description,$ip){ $queryb = mysql_query("SELECT * FROM benefits WHERE b_id = $benefits2"); while ($row = mysql_fetch_array($queryb)) { $benefit_list = $row['b_id']; } if (isset($benefits2)&&( $benefit_list!== $benefits2)) { Do something here! } } Thanks for your help! |
