PHP - String Concatenation Problem
I am using the code posted here to do something with a third party software
http://www.interwork...trusted-tickets
however its utterly frutrating that something as simple as
$fullUrl = "http://{$server}/trusted/{$ticket}/{$url}";
returns me the following
moOaH6BAKFMGGszd_IQHTvpAhttp://<server>/trusted/1/views/<dashboard>?format=png
instead of
http://<server>/trusted/moOaH6BAKFMGGszd_IQHTvpA/views/<dashboard>?format=png
completely beats me. Any idea why ? Is it something to do with the variable $ticket which has the value of moOaH6BAKFMGGszd_IQHTvpA in this case ?
Similar Tutorialsi want to do it with cURL-Multi since this is the most pretty way to do it! Well i am not sure bout the string concatenation. How to do it - Note i want to fetch several hundred pages: see the some details for this target-server sites - /(i have to create a loop over several hundred sites) siteone_dot_com?show_subsite=9009 siteone_dot_com?show_subsite=9742 siteone_dot_com?show_subsite=9871 and so on and so fort how to appy this loop into the array of the curl-multi <?php /************************************\ * Multi interface in PHP with curl * * Requires PHP 5.0, Apache 2.0 and * * Curl * ************************************* * Writen By Cyborg 19671897 * * Bugfixed by Jeremy Ellman * \***********************************/ $urls = array( "siteone", "sitetwo ", "sitethree" ); $mh = curl_multi_init(); foreach ($urls as $i => $url) { $conn[$i]=curl_init($url); curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string curl_setopt($conn[$i],CURLOPT_FOLLOWLOCATION,1);//follow redirects curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout curl_multi_add_handle ($mh,$conn[$i]); } do { $n=curl_multi_exec($mh,$active); } while ($active); foreach ($urls as $i => $url) { $res[$i]=curl_multi_getcontent($conn[$i]); curl_multi_remove_handle($mh,$conn[$i]); curl_close($conn[$i]); } curl_multi_close($mh); print_r($res); ?> I am trying to figure out how to have an if statement in the middle of strings I am trying to concatenate. I have a from that has a address1 and address2, where address2 often does not exist. So I want to only add that line if there is actually content. I was trying something like the following, but that is giving me an error. I am pretty new to php, so I can't seem figure it out. Any help would be greatly appreciated. Code: [Select] "<p><strong>Address 1: </strong><br>" . $address1 . "<br>" if ( isset($address2) ) { echo . $address2 . "<br>" } . $city . ", " . $state . " " . $zip .

Well - i want to do this with curl-multi since this is the most advanced way to do this: I see i have an array that can be filled I have to try it out...!! Well, I'm not pretty sure - but judging by the low level of PHP i have: I think that i may need a double array to define the URLs like: Can i do like so?: $urls = array( "siteone" => "suche_schul_db.html?show_school=%i", "sitetwo" => "suche_schul_db.html?show_school=%i", "sitethree" =>"suche_schul_db.html?show_school=%i" ); $params = array ( for ($i = 1; $i <= 10000; $i++) { // body of loop } // well i have to define the variables in a open form like abvove nand not below: // better than doing it like so: "siteone" => array(9009, 9742, 9871), ); then pass them to curl-multi as: foreach ($urls as $id => $url) { foreach ($params[$id] as => $param) { $i = $id . $param; $finalurl = sprintf($url, $param); $conn[$i] = curl_init($finalurl); I don't know if that's fits the needs tip that i am looking for but I hope so ;-) Can i do like so [see above]? What do yu think. i send you many greetings martin I have a table (applicants) which has a number of fields including 5 for potential 'parties' - these are party1, party2, party3, party4 and party5. Any particular applicant will always have two parties but could have any number up to 5. I need to export a pdf (which I can do) but I need it to include data drawn from the applicants table in the format: party1, party2 and party3 OR party1 and party2 etc that is, each party has a comma after it except the last but one, which has no comma but an 'and'. (I hope this is clear enough!) I can't work out how to do this for a varying number of 'parties'. Any suggestions/answers gratefully received. How do I add a space in my concatenation? What I have down below doesn't work. $result[0] .$result[1] problem is when i select unpaid in drop down box it not show the expected result.

I've gone from 0 to 40 in about 2 months, as far as savviness is concerned. I am working on a form that I want to display array information of two things (shortname and fullname) in a drop-down list. I am thinking I need to do some sort of concatenation to achieve this, or would I do an array within an array? The array is defined in a value object and that draws the id, shortname and fullname. Shortname is the defined label in that file. In the form page, i have the LO ['full_name'] => LO ['label']... this inputs the right information into the database, but shows the full name. I want the drop-down to show it as following: Shortname|Fullname. This will be used in a couple of places once I get on the right track on how to accomplish this. I would be accepting of any help, as well as any resourced that could answer my question and help me finish this form. Cheers, ESK
Is there a subtle difference between Thank you. I can successfully concatenate strings and vars to assemble a php var using an echo statement like this: Code: [Select] echo "<input type='radio' id='radio_btn_" . $Row['question_number'] . "_0' name='question[question_" . $Row['question_number'] . "]' value='0' checked='checked' />"; However, when attempting to reference the same var in an IF statement, I can't seem to get the syntax right. I know this syntax is wrong, but I list it for reference to describe the issue I am trying to solve. Code: [Select] if ($_POST['radio_btn_' . $Row['question_number'] . '_0'] == '0'){ I also tried curly braces but can't arrive at a solution. Any advise would be appreciated. I'm wondering if this is at all possible:- Code: [Select] $i = 7; $row_item['comment$i_name'] = "john"; with the $i in $row_item['item$i_id'] being replaced with whatever $i is set as sort of like this:- $row_item['comment.'$i'._name'] Is this sort of concatenation possible inside array element names as I can't seem to get it to work? Hello Guys can anyone help me with this? Code: [Select] <?php $common_words = array(" the ", " is "); $title = " The dog is chasing the boy "; $title = strtolower($title); $title_array = explode(" ", $title); $title_words = array(); foreach($title_array as $word) { $title_words[] = str_replace($common_words, " ", $title); } $text = " The dog is chasing the boy. This is an irrelevant sentence. The boy runs away from the dog. This is another irrelevant sentence. "; $sentence = strtok($text, ".?!"); $summary = ''; while ($sentence !== false){ foreach($title_words as $word) { if(strstr($sentence, $word)) { $summary .= $sentence . '. '; } } $sentence = strtok(".?!"); } echo $summary; ?> when i execute this code i get a blank page. I think the problem is on this line: $title_words[] = str_replace($common_words, " ", $title); The expected output is: The dog is chasing the boy. The boy runs away from the dog. Hey guys. I'm having a problem with my code and I can not seem to understand what's wrong.. My suspicion is that the $string gets too big or something.. but I'm not quite sure. $subject = $_GET['sub']; $message = explode("|", $_GET['msg']); $sendto = "email"; $sendfrom = "email"; foreach($message as $user){ $user = explode(":", $user); $activity1 = base64_decode($user[0]); $activity2 = base64_decode($user[1]); $activity0 = base64_decode($user[2]); $string .= "Activity0: " . $activity0 . "<br>" . "Activity1: " . $activity1. "<br>" . "Activity2: " . $activity2 . "<br>- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -<br>"; } if($subject && $activity1 && $activity2 && $activity0){ $header = 'Content-type: text/html; charset=iso-8859-1' . "\r\n" . 'From: ' . $sendfrom . "\r\n"; mail($sendto, $subject, "<html>" . "<center>" . "<br><br><br>" . " - - - " . "Program logged this activity" . " - - - " . "<br>" . $string . "<br>" . "<b> - meh -</br></center></html>", $header); } else { echo "Failed?"; } So the main point is that a program sends the required information to the php script and it proceeds by splitting it up and showing it in an organized way.. and then sends it to an email. This works flawless until some point where the message gets too big(?) and it'll do else { echo "Failed?"; } instead... Do you guys have any idea what's wrong? Thanks in advance. Hello PHPFreaks, i have 2 problems. The first problem is, that what i want help to is on my other computer. And its not possible for me to get to it atm. So i'll do it as good as i remember. My second problem is, i made a website and i want a login on one of the pages. I made a form etc. The username field is called 'usernamebox' and the password field is called 'passwordbox'. So, in the php part I do like this. <?php $username_string = $_POST['usernamebox']; $password_string = $_POST['passwordbox']; rest of code ... ?> Is there any problem doing that, because my SQL server shows me error every place i try to connect it with the strings? I need to see if someone can point out something that I have missed or maybe even point me in the right direction on something. I have a PHP script that I have run into a problem on. The basic idea of the script is that it will send out HTML formatted emails to users of my web site. The problem I am running into is storing the HTML content in memory so I can do a str_replace() looking for certain markers in the HTML and replace them with lets say the users name and custom links that pertain to the particular user that the email is going to. Currently the HTML is being stored in a MySQL database, but I have already tried reading it from a flat file. Each time I only get the first 1024 characters returned. The problem seems to be that I am running into a PHP STRING limitation. From the reading that I have done on the subject, the limit should be 1024 characters PER LINE with the variable able to hold somewhere around 8MB worth of data. I can tell you that it does not matter how many \n I put into the HTML I still only get the first 1024 characters. Is there a way I can get the entire HTML file (about 12k characters) in memory so I can work with it and hand it off to the mail function? Thanks, whit3fir3 Hello guys, I have a form where you can select a score between 0 and 10(only integers).
I want to check if the value that I recive, is integer.
Im using this code(exemple):
$integer = intval($_POST["p1"]);
if(is_int($integer)){
echo 'INT';
} else {
echo 'NO INT';
}
My problem is that if it recive letters, the conversion converts it to 0, and it says that it is integer.
So with this method I should discard the 0.
You guys know a method to avoid that?
Thank you guys
I normally don't have a problem with concenation, but for some reason I can't get it work in this case. I have two form variables: firstname_ord and lastname_ord. I have tried concenating them several ways, and get nothing afterwards. attempt 1: $lastname = "firstname_ord" . " " . "lastname_ord"; attempt 2: $firstname = "firstname_ord"; $lastname = "lastname_ord"; $fullname = $firstname . " " . $lastname; attempt 3: $fullname = "firstname_ord"; $fullname = $fullname. " " . "lastname_ord"; attempt 4: $fullname = "firstname_ord"; $fullname .="lastname_ord"; attempt 5: $fullname = (string)"firstname_ord"; $fullname .= " "; $fullname .=(string)"lastname_ord";

"</a> </td> I'm looking at this line in the code. I realise it's currently in the wrong syntax but I'm just trying multiple different variations. At the moment I'm actually just trying to make it go to a static link but my real goal is to - get it to pick up the id number, of the id row I click, and concatenate that with the rest of my address string. Then use that as the href. Something like this: - "'Details/' + $id + '/index.php'" It's really confusing me though inside this loop and for some reason the id number is being picked up as an int, by the looks of things. It's getting above my level of understanding. Any chance one of you masters would through a n00b a lifeline?
