PHP - Function Array Output Is Not Index As Expected
Here is my function which almost works as expected:
<?php function find_value($array,$value) { for($i=1;$i<sizeof($array);$i++) { if($array[$i] == $value) { echo "$i . $array[$i]<br />"; return; } } } ?> And I call the function like so: <?php $names = array('Jason','Mike','Joe'); $name = 'Joe'; find_value($names,$name); ?> And the output is: 2 . Joe According to my understanding of Arrays, Joe would be index 3 BECAUSE my counter starts at 1 in my for loop??? Why is the result like this? What am I not understanding here? Similar TutorialsI have a problem with the below code: Code: [Select] <?php $sql_ranks = ("SELECT vtp_members.id, vtp_members.name, vtp_members.teamleader, teams.team_name, count(vtp_tracking.id) surfs FROM vtp_members, vtp_tracking, teams WHERE vtp_members.team_id=".$_GET['t']." AND vtp_tracking.credit_members_id=vtp_members.id AND vtp_tracking.action_date > '$last_sunday' AND vtp_tracking.action_date < '$next_sunday' GROUP BY teams.team_name ORDER BY surfs DESC"); $rsranks = mysql_query($sql_ranks); echo "<br><table align='center' valign='top' border='0' width='300px'> <tr><td colspan='2' align='center'><font size='2px'><b>Team Rankings (Current Week)</b></font></td></tr> <tr><td><font size='2px'><b>Team</font></td><td align='right'><font size='2px'>Total Surfs</font></td></tr>"; while ($row = mysql_fetch_array($rsranks)) { echo "<tr><td><font size='2px'><b>".$row[team_name]."</font></td><td align='right'><font size='2px'>".$row[surfs]."</font></td></tr>";} echo "</table>"; ?> Problem is that the last output (".$row[surfs].") is the same for all teams. It seems it is not making a total of all id's and not per team_name. anyone can see what I am doing wrong. I need to sort by team_name and the surfs should display the total of the members with team_id is ".$_GET['t']." I have this code Code: [Select] $nArr = array('A', 'B', 'C', 'D', 'E', 'F'); $counter = 3; while ($counter > 0) { $chunkedValues[$counter][0] = 1; for ($j = 0 ; $j < $counter ; $j++) { $chunkedValues[$counter][$j + 1] = $nArr[$j]; } $nArr = array_slice($nArr, $counter--); } var_dump($chunkedValues); that outputs: Code: [Select] array 3 => array 0 => int 1 1 => string 'A' (length=1) 2 => string 'B' (length=1) 3 => string 'C' (length=1) 2 => array 0 => int 1 1 => string 'D' (length=1) 2 => string 'E' (length=1) 1 => array 0 => int 1 1 => string 'F' (length=1) But i need this index structu Code: [Select] array 0 => array 0 => int 1 1 => string 'A' (length=1) 2 => string 'B' (length=1) 3 => string 'C' (length=1) 1 => array 1 => int 1 2 => string 'D' (length=1) 3 => string 'E' (length=1) 2 => array 2 => int 1 3 => string 'F' (length=1) I want to avoid loops with ceil. Any idea? thanks for your time. Hi all,
Wondered if anyone could assist?
On the following website the footer is not displaying as expected and cannot see why:

Any other pages on the website show the footer correctly.
Thanks.
I am trying to simulate an ad expiration and carry out an action if the ad is expired. And I cannot get the if/else to work properly... I've tried many variations and I cannot see what I am doing wrong here. Any tips please 3 hours and counting of no solution! $ad_start = time()-14 . "<br />"; // 14 days from today in the past (negative) echo $ad_start; $current_time = time() . "<br />"; // current epoch time echo $current_time; $days_past = $ad_start - $current_time; // days past echo "<br />$days_past days have past since the ad started!<br />"; if($days_past <= 14) { echo "<br />Ad is less than 14 days. Not expired."; } else { echo "<br />Ad is over 14 days. Expired."; } I've got a few hours in this, read the manual on return (and it appears my print_r should be working!).. And I am unable to get print_r() to output the contents of my function array. What am I doing wrong? function getStateName() { $stateName = array("Alabama","Florida","Nevada"); return $stateName; } echo "<pre>"; echo print_r($stateName); echo "</pre>"; I am trying to load all rows from a table in a database into a table on a webpage. I cannot understand why the following code does not work: Code: [Select] <?php ... echo "You are currently in a fleet. The details of the fleet are below.<br>"; $fleetName = $_SESSION['charFleetName']; $sqlFleetDetails = "SELECT * FROM `$fleetName`"; $queryFleetDetails = mysql_query($sqlFleetDetails); echo "<table>"; echo "<tr>"; echo "<th>Pilot</th>"; echo "<th>Ship</th>"; echo "<th>Type</th>"; echo "</tr>"; while($rowFleetDetails = mysql_fetch_array($queryFleetDetails)) { $charId = $rowFleetDetails['charId']; $charName = $rowFleetDetails['charName']; $shipHull = $rowFleetDetails['shipHull']; $shipType = $rowFleetDetails['shipType']; echo "<tr>"; echo "<td><a href=\"#\" onClick=\"CCPEVE.showInfo{1377, " . $charId . "}>" . $charName . "</a></td>"; echo "<td>" . $shipHull . "</td>"; if($shipType == 1) echo "<td>Logistics</td>"; if($shipType == 2) echo "<td>DPS Boat</td>"; if($shipType == 3) echo "<td>Sniper 120Km+</td>"; if($shipType == 4) echo "<td>Off-grid Booster</td>"; echo "</tr>"; } echo "</table><br>"; I originally had the $rowFleetDetails['charId'] and others in the echo instead of loading them into variables then echoing the variables but changed it to see if that was working, neither is. If I add an extra line outside of the while loop to echo the output of the array then the information is displayed fine, so I know that the information is being transferred from the table into the array correctly, but why is it not outputting properly in the While loop? I created a function called converter. My code doesn't look like it processes anything after the first if . This is what is displayed in browser. Convert a String original string: roses Are red, violets are blue.... converted string: roses are red, violets are blue.... converted string: roses are red, violets are blue.... converted string: roses are red, violets are blue.... <html> <head> <title>Create a PHP Function to Convert a String</title> </head> <body bgcolor="pink"> <h2>Convert a String</h2> <?php $phrase = "roses Are red, violets are blue...."; function converter($arg1, $arg2){ if($arg1="lower"){ return strtolower($arg2); } elseif ($arg1="upper"){ return strtoupper($arg2); } else /* if($arg1="title")*/{ return ucwords($arg2); } } print "original string: ".$phrase."<br />"; print "converted string: ".converter("upper",$phrase)."<br />"; print "converted string: ".converter("lower",$phrase)."<br />"; print "converted string: ".converter("title",$phrase)."<br />"; ?> </body> </html> Hello, Currently have an array like looks like the following when using print_r($session->items): Array ( [F1225] => 1 [EDS11147317] => 1 [1156D6RE001] => 1 [I111ADE47946] => 1 [S679AQ339] => 1 [S67914599] => 1 [CH111337631254] => 1 [S6787903647] => 1 [A11144O189] => 1 [F11144520] => 1 [121584Q12] => 1 [I11144661ADE] => 1 [S678829NB] => 1 ) I am trying to check if an item is in the array and if so, display a different result but currently every item says it is in the array when they are not (unless my logic is off...from the items I am looking at some should be included and some should not..but the below code is showing every item as having the same result). Example: foreach ($items as $item) { if (in_array($item->ItemID, $session->items)) { //$session->items is the array output above echo "In Array"; } else { echo "NOT in Array"; } } Currently everything say "In Array" when some should not. Am I using the in_array incorrectly? Thanks Everyone. Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. I am trying to be true to the principle that logic and presentation should be kept separate. However, the only way to generate dynamic content and output is using something like PHP, so there is somewhat of a conflict. I just wrote this Function, and I am curious if it breaks the principle above... /** * Returns Online Status Indicator Markup * * Takes User's Last Activity and determines the User's Online Status. * Returns HTML for appropriate Online Status Indicator. * * @param DateTime $lastActivity MySQL DateTime format (yyyy-mm-dd hh:mm:ss) * @return string */ function getOnlineStatus($lastActivity){ // strtotime() converts DateTime format (yyyy-mm-dd hh:mm:ss) into a Unix Timestamp (seconds). // time() is current time measured in the # of seconds since Unix Epoch (January 1 1970 00:00:00 GMT). $minutesOnline = (time() - strtotime($lastActivity))/60; // Determine Online Status. if ($minutesOnline < 15){ // Member Online $indicator = '<img src="/images/Light_Green_10.png" width="10" alt="Member Online" /><br />'; }else if ($minutesOnline < 30){ // Member Idle $indicator = '<img src="/images/Light_Yellow_10.png" width="10" alt="Member Idle" /><br />'; }else{ // Member Offline $indicator = '<img src="/images/Light_Gray_10.png" width="10" alt="Member Offline" /><br />'; } return $indicator; }//End of getOnlineStatus Thanks, Debbie Hey Guys, I'm building a site to view images on, basically the image detail is stored in a database, the site is then accessed and a standard select query is used. I then get the image name etc pulled from the database. Is there a way to save that image name into a variable and get it to display on a form that is run from a function - completely independent to my viewing code...
Some sort of global variable, but that could change each time I viewed a different photo - and wouldn't have any effect on anyone else browsing the site etc - so the correct image name would always be passed? The below is outputting: Array Fatal error: Unsupported operand types in /home/zyquo/public_html/area51entertainment.co/maintenance/home.php on line 28 So clearly $project_row_num is coming out as an array, and the multiplication is failing because its got a string not a number. I just don't see why it's getting an array out of $project_row_num. <?php $num_projects=15; $scroller_projects=""; require_once 'db_select.php'; $project_query_num="SELECT COUNT(*) FROM $tbl_name"; $project_result_num=mysql_query($project_query_num); $project_row_num=mysql_fetch_assoc($project_result_num); echo $project_row_num; //if($project_row_num <= $num_projects){ $project_query="SELECT * FROM $tbl_name"; $project_result=mysql_query($project_query); /*} else{ $project_query="SELECT * FROM $tbl_name WHERE project_release_date BETWEEN $start_date AND $end_date LIMIT 0,$num_projects"; $project_result=mysql_query($project_query); }*/ $i=1; while($project_row=mysql_fetch_array($project_result)){ extract($project_row); $scroller_projects.='<div class="project_entry" tabindex="'.$i.'" onclick="sndReq(\''.$project_id.'\');">Test</div>'; $i++; } if($project_row_num==""){ $films_row_num=$num_projects; } $scroller_width=$project_row_num*114; $content=' <div class="video_scroller_wrapper"> <div class="video" id="tabs"> </div> <div class="recentfilms_wrapper"> <div class="left_arrow"><img src="arrow_left.png" alt="Left" title="" class="arrow_left" onclick="jumpLeft(\'recentfilms\')" onmouseover="startScrollLeft(\'recentfilms\')" onmouseout="stopScroll()" /></div> <div id="recentfilms"> <div id="scroller" style="width: '.$scroller_width.'px;"> '.$scroller_projects.' </div> </div> <div class="right_arrow"><img src="arrow_right.png" alt="Left" title="" class="arrow_right" onclick="jumpRight(\'recentfilms\')" onmouseover="startScrollRight(\'recentfilms\')" onmouseout="stopScroll()" /></div> </div> </div> <div class="news_wrapper"> <div class="news"> <div class="news_title"><span class="category_title_text">Latest News</span></div> <div class="news_text"> <iframe src="http://www.indiegogo.com/project/widget/75876?a=9030" style="width: 224px; height: 429px; position: relative; left: 3px; top: 15px; border: 0px; overflow: hidden;"></iframe> </div> </div> </div> '; ?> I have an array and I would like to insert commas and the word 'and' to make a sentence using an array. For example... $sports = array(baseball, soccer, tennis); Ted played baseball, soccer and tennis or Ted played baseball, soccer, boxing and tennis What's the best way to do this? I'm kind of a beginner, but I really need this script and I'm not sure how quite to do it as needed... With some html forms I need it so you can type a name in then click submit, then (with php) it will save that text into a text file or something. Later, when I hit a different button it will randomly display one of those texts/names from before. Hi all What I am trying to achieve is a for each loop for the following output Code: [Select] Array ( [result] => success [source] => getDirectory [success] => Array ( [0] => /root/mc/world/data/ [1] => /root/mc/world/level.dat [2] => /root/mc/world/level.dat_old [3] => /root/mc/world/players/ [4] => /root/mc/world/players/herghost.dat [5] => /root/mc/world/region/ [6] => /root/mc/world/region/r.-1.0.mcr [7] => /root/mc/world/region/r.0.0.mcr [8] => /root/mc/world/session.lock [9] => /root/mc/world/uid.dat ) ) How would I go about saving each path from the [success] output? Basically I wish to loop through the array and delete the files. Many Thanks Hi all I am having massive problems comparing the out put of array, basically my end result is to choose a selected option on a drop down in a form. I am trying to compare the output of ['allow-nether'] which is either true or false in my file. Here is what I have tried //code to get file contents Code: [Select] $file_handle = fopen("saves/server.properties", "rb"); $vars = array(); while (!feof($file_handle) ) { $line_of_text = fgets($file_handle); $parts = explode('=', $line_of_text); //if date not required if ( !isset($parts[1]) ) { continue; } $vars[$parts[0]] = $parts[1]; } Code: [Select] <?php //allow nether =false in file echo "1 " .$vars['allow-nether']; if ( $vars['allow-nether'] == true ) { echo '<br>2 selected="selected"';} if ( $vars['allow-nether'] == false ) { echo '<br>3 selected="selected"';} if ( $vars['allow-nether'] == "true" ) { echo '<br>4 selected="selected"';} if ( $vars['allow-nether'] == "false" ) { echo '<br>5 selected="selected"';} if ( $vars['allow-nether'] === true ) { echo '<br>6 selected="selected"';} if ( $vars['allow-nether'] === false ) { echo '<br>7 selected="selected"';} if ( $vars['allow-nether'] === "true" ) { echo '<br>8 selected="selected"';} if ( $vars['allow-nether'] === "false" ) { echo '<br>9 selected="selected"';} ?> which outputs: Code: [Select] 1 false 2 selected="selected" and if I set the file to allow-nether=true Code: [Select] <?php //allow nether =true in file echo "1 " .$vars['allow-nether']; if ( $vars['allow-nether'] == true ) { echo '<br>2 selected="selected"';} if ( $vars['allow-nether'] == false ) { echo '<br>3 selected="selected"';} if ( $vars['allow-nether'] == "true" ) { echo '<br>4 selected="selected"';} if ( $vars['allow-nether'] == "false" ) { echo '<br>5 selected="selected"';} if ( $vars['allow-nether'] === true ) { echo '<br>6 selected="selected"';} if ( $vars['allow-nether'] === false ) { echo '<br>7 selected="selected"';} if ( $vars['allow-nether'] === "true" ) { echo '<br>8 selected="selected"';} if ( $vars['allow-nether'] === "false" ) { echo '<br>9 selected="selected"';} ?> Gives: Code: [Select] 1 true 2 selected="selected" What am I doing wrong? Hi,I
I'm trying to setup Paypal Pro on a website - have everything working - but need to grab the 4th & 6th key values from the results given from the Paypal response and having difficulty with the task.
See the code that prints the response and the response sent from Paypal below - I need to grab the values for [TRXRESULT] and [TRXRESPMSG]
echo('<pre>');
print_r($PayFlow->getResponse());
echo('</pre>');
and here's the response I get from Paypal on script execution - this is an example of a failed transaction:
Paypal Response
Array
(
[RESULT] => 36
[RPREF] => RPC5B24581A2
[RESPMSG] => Transaction failed: Fail to obtain approval for the online transaction
[TRXRESULT] => 23
[TRXPNREF] => EUJPC36F2092
[TRXRESPMSG] => Invalid account number: Unsupported Credit Card type
)
Again, I want to grab the values from [TRXRESULT] and [TRXRESPMSG] and assign them to local variables so i can work with them within the local php script.
Example: $trxresult and $trxrespmsg
Here's part of the class (file name is Class.Payflow.php find on Github) that pertains to this snippet of code in question:
Class.Payflow.php
/**
* @uses Gets the response from Paypal.
* @access Public
* @param None.
* @return Array/String - Returns an array of Paypal's response or empty string if not return.
* @example $PayFlow->getResponse();
*/
public function getResponse() {
if($this->response) {
return $this->response;
}
else {
return '';
}
}
Thanks in advance for help w/this one!
I tried searching for this but I didn't find anything. I have some php code that when loaded from a web page draws some numbers from a database and outputs. Should be no problem I thought The code involves a mysql query. This is an edited sample: $query = "SELECT `count` FROM `uc` WHERE `id` = 17"; $result = mysql_query($query, $dbh) or die(mysql_error()); $row = mysql_fetch_array($result, $dbh); Now after this I normally access $row as $row[0] and this works great most of the time. However about 10% of the time it returns an error: "Notice: Undefined offset: 0" My investigation using print_r($row); shows that sometimes it returns Array ( => 619 ) and sometimes it returns Array ( [count] => 619 ) Why the inconsistency? How can I make it always use a numeric index? Hi i turned my output_buffering to true on my php.ini because i need some of its features for trailing the system my problem now is when im getting .csv file using header function, it seems that it gives me the source code of the interpreted code instead of the expected .csv contents. Here is the source code echo $who; echo $ecrn; $myFile = "($who)$info_value[RecordName]-$ecrn"; header('Content-Type: text/csv; charset=utf-8'); $content = "Content-Disposition: attachment; filename=".$myFile.".csv"; header($content); $output = fopen('php://output', 'w'); $sql = "SELECT * FROM classrecordvalue"; $query = mysql_query($sql); // loop over the rows, outputting them while ($row = mysql_fetch_array($rows)) fputcsv($output, $row); im just wondering does output_buffering true in php.ini affect the output here? if so any other suggestions there of how i can download .csv files using php? thank you much for the people who will help Hi, got a problem with my arrays, every string gets duplicated 11 times instead of just one time. How to fix this? |
