PHP - Is There A Way To Join Several Arrays Stored In One Variable?
Hi,
I have this problem I really hope someone can help me with. I have a variable that stores several arrays. The content of the variable is as follows: Code: [Select] print_r(array_values($array)); Array ( [0] => Value 0) [1] => Value 1) [2] => Value 2) [3] => Value 3) ) Array ( [0] => Value 4) [1] => Value 5) [2] => Value 6) [3] => Value 7) [4] => Value 8) ) Array ( [0] => Value 9) [1] => Value 10) [2] => Value 11) [3] => Value 12) [4] => Value 13) ) Is there a way to join this multiple arrays into a single array? I do not need to keep the Key, as all of the values contains text that I only want to sort with sort();. If I sort it like this, it will only come out as a,b,c,d - a,b,c,d, not a, a, b, b, c, c, d, d and so forth. The php script that creates this array is as follows: Code: [Select] while($row = mysql_fetch_array($run_mysql_query)){; $models = $row['text_value']; $attribute1 = $row['attribute1']; $attribute2 = $row['attribute2']; $array = explode(',', $models); foreach($array as &$value) { $value = $row['varchar_value'] . " - " . $value . " - " . $attribute1 . " - " . $attribute2; } I will appreciate any help! Similar TutorialsI have code that queries two tables for example... Code: [Select] $checkfordue = mysql_query("SELECT stuID FROM ".$conf['tbl']['homework']." , ".$conf['tbl']['homeworktable']." WHERE ".$conf['tbl']['homework'].".TID = '$newID' && ".$conf['tbl']['homeworktable'].".TID = '$newID' && ".$conf['tbl']['homeworktable'].".ID = '$ID' && ".$conf['tbl']['homework'].".turnin = '2' && ".$conf['tbl']['homework'].".homeworkID = ".$conf['tbl']['homeworktable'].".ID ORDER BY stufirstname, stulastname"); WHILE($checkdue = mysql_fetch_array($checkfordue)) {etcAnd the above code has been working fine. The question really is about using JOIN instead of what I did. And if you could please explain join left as well. What are the benefits of using join rather then writing the query like I did. Hey all, I'm well aware of associative arrays (key/value pairs) and how you can index them in an array like this: $character = array (name=>"John", occupation=>"Programmer", age=>22, "Learned language "=>"PHP" ); Then it makes sense to iterate through the key/value pairs of the array using foreach: foreach ( $character as $key=>$val ){ print "$key = $val<br>"; } However, I was watching a video tutorial where he created a $_SESSION array and then created an array associative array: $_SESSION['cart'] = array(); [/PHP] Then he added a function add_to_cart: function add_to_cart($id){ if(isset($_SESSION['cart'][$id])){ $_SESSION['cart'][$id]++; return true; } else { $_SESSION['cart'][$id] = 1; return true; } return false; } Now that $id variable holds an id converted to integer from the dataabse. So if first item is clicked, id holds a value of integer 1. When I see this: $_SESSION['cart'][$id] I see an array that holds two indexes, each index containing an associative array: [[array() => ''], [1 => '']]. So at index 0 of $_SESSION is [array() => '']. But then he uses the foreach iterator like this: function total_items($cart){ $items = 0; if(is_array($cart)){ foreach($cart as $id => $qty){ $items += $qty; d } } return $items; } Now I'm very confused. As you can see in that foreach method, it says that $id (and its corresponding value) is an associative array of $cart array, not $_SESSION array. I don't see how that happened. I thought $cart and id$ were distinct indexes of $_SESSION. I don't see how $id is a key of the $cart array. Thanks for any explanation to clear my confusion. The path to a image is stored in a variable and I need to display this image in the email. Can someone help me. This is my current attempt and nothing is happening. But the variable passes the URL correctly. Code: [Select] <TABLE BORDER='0'> <TR> <TD align='left' width='370'><img src='".$dis_logoimg."' width='370' height='86' /></TD> </TR> </TABLE> Hi, In some cases I need to execute a default query , so I am storing the SELECT statement in a variable like this and executing it: Code: [Select] $default_query="SELECT * from user where userid='$userid'"; $user_query=mysql_query($default_query); The above code returns an empty results. But if I execute it without the variable it works fine. Code: [Select] $user_query=mysql_query("SELECT * from user where userid='$userid'"); Am I syntatically wrong somewhere? Currently, I'm trying to write a contact form, and perhaps I'm overcomplicating it, but I have a public variable called $EquationAnswer that stores the answer to the Captcha method (randomised maths question) and whenever the page reloads, it creates a new instance of the Contact class, which then erases the value that has been stored in that variable.
What I'm trying to achieve is keeping the value stored even after a new instantiation of the class. I remember from a class at University that static was a way to do this, but this was in C#.
<?php class Contact { public $EquationAnswer; public function CaptchaCreation() { $SignArray = array('+', '×', '-'); $NumberOne = rand(1, 9); $NumberTwo = rand(1, 4); if($NumberOne < $NumberTwo) $SignIndex = rand(0, 1); else $SignIndex = rand(0, 2); $Sign = $SignArray[$SignIndex]; $EquationString = $NumberOne." ".$Sign." ".$NumberTwo; switch($Sign) { case "+": $Answer = $NumberOne + $NumberTwo; break; case "-": $Answer = $NumberOne - $NumberTwo; break; case "×": $Answer = $NumberOne * $NumberTwo; break; } $this->EquationAnswer = $Answer; return $EquationString; } public function EchoContactForm() { $CaptchaMessage = $this->CaptchaCreation(); echo "<form method='POST' action=''>\n\n"; echo "\t\t\t\t\t<table>\n\n"; echo "\t\t\t\t\t\t<tr><td>Name: </td><td><input type='text' name='name' /></td></tr>\n"; echo "\t\t\t\t\t\t<tr><td>Email: </td><td><input type='text' name='email' /></td></tr>\n"; echo "\t\t\t\t\t\t<tr><td>Subject: </td><td><input type='text' name='subject' /></td></tr>\n"; echo "\t\t\t\t\t\t<tr><td>Message: </td><td><textarea rows=5 name='message'></textarea></td></tr>\n"; echo "\t\t\t\t\t\t<tr><td>What is: ".$CaptchaMessage."?</td><td><input type='text' name='captcha' /></td><td></td></tr>\n"; echo "\t\t\t\t\t\t<tr><td colspan=2 style='text-align: right'><input type='submit' name='submit' value='Send' /></td></tr>\n\n"; echo "\t\t\t\t\t</table>\n\n"; echo "\t\t\t\t</form>\n"; } public function ContactFormValidation($Name, $Email, $Subject, $Message, $CaptchaInput, $CaptchaAnswer) { echo $CaptchaAnswer; $ErrorsArray = array(); if(strlen($Name) == 0) array_push($ErrorsArray, "You must provide a name."); if(strlen($Email) == 0) array_push($ErrorsArray, "You must provide an email."); if(strlen($Message) == 0) array_push($ErrorsArray, "You must provide a message."); if(strlen($CaptchaInput) == 0) array_push($ErrorsArray, "You must provide an answer to the maths question."); if($CaptchaInput != $CaptchaAnswer) array_push($ErrorsArray, "Incorrect captcha answer."); if(count($ErrorsArray) > 0) { echo "There are ".count($ErrorsArray)." Errors: <br />"; foreach($ErrorsArray as $E) echo $E."<br />"; } else { return true; } } } ?>^ That's the Contact class, and the main function that I want to focus on is the last one, "ContactFormValidation()". From the contact form page (which is within a template), I want it to send the EquationAnswer variable to that function so that it can compare what the user has input. <?php //Instantiate the contact class include './inc/PHP/classes/ContactClass.php'; $ContactClass = new Contact; if(!isset($_POST['submit'])) { $ContactClass->EchoContactForm(); } else { $NameInput = $_POST['name']; $EmailInput = $_POST['email']; $SubjectInput = $_POST['subject']; $MessageInput = $_POST['message']; $CaptchaInput = $_POST['captcha']; $CaptchaAnswer = $ContactClass->EquationAnswer; //Tried echoing out what is in the variable but it produces nothing because the contact class is a new instance. //echo $CaptchaAnswer; if($ContactClass->ContactFormValidation($NameInput, $EmailInput, $SubjectInput, $MessageInput, $CaptchaInput, $CaptchaAnswer) == true) { //Mail function } } ?>Any help would be appreciated. Cheers. Hi, I have a function where I want to sort an an array of this type: 0 = {'fruit' => 'banana', 'color' => 'yellow', 'age' => '1', 'weight' => '2', 'brand' => 'dole', 'store' => shaws'} 1 = {'fruit' => 'apple', 'color' => 'red', 'age' => '3', 'weight' => '5', 'brand' => 'fuji', 'store' => 'foodmaster'} etc etc. I then want to array_multisort this array with different parameters. One way is to sort by fruit, then color, then brand. The second way by age, then store. Code: [Select] //This is how I sort it for my first way //Let's call the array $rows function sort($rows) { foreach($rows as $key => $value) { $fruit[$key] = $value['fruit']; $color[$key] = $value['color']; $brand[$key] = $value['brand']; } array_multisort($fruit, SORT_ASC, $color, SORT_ASC, $brand, SORT_ASC $rows); } I want to try to reuse this function by passing in the keys that I want to sort with. Like doing sort($rows, array('fruit', 'color', 'brand')), then sort($rows, array('age', 'store')). Is this possible?

I'm having troubling with trying to create a function to spit out a single array with the following array. I can write it in a away that looks through the arrays manually. the results i am trying to generate is that each item in generated array. Array to convert array( "account" => array( "login", "register", "logout", "edit", ), "p" => array( "report", ), "array1.0" => array( "array2.0" => array( "array3.0", "array3.1 ), "array2.1", ), generating the array will look like this
Array ( [0] => account [1] => account/login [2] => account/register [3] => account/logout [4] => account/edit [5] => p [6] => p/report [7] => array1.0 [8] => array1.0/array2.0 [9] => array1.0/array2.0/array3.0 [10] => array1.0/array2.0/array3.1 [11] => array1.0/array2.1 ) The idea is that id generates a single array with combined labels and arrays inside, etc. I just can't figure out how to create a script that will create this array even If I add a new value or array.
Often times I need to convert between PHP Arrays, MySQL, XML, JSON sqlite etc. Lately I've been just building PHP arrays with all the data. Its a big hassle though when theres a lot of data. I'm thinking I should have one central location that I store data in, then export to other formats from there, but I dont know what that central location should be. I like MySQL because I'm used to it. Sometimes its not an option though, like if I need to make a really light script, I dont want the hassle of connecting to MySQL. Would XML be the best place to store data, then from the XML file I can convert it to whatever format I want?
I'm working on a project and cannot figure out why one piece of code works in one project but not in this one. Code: [Select] $username = "voltageme5"; $result = $mysqli->query("call usernameCheck($username)"); returns string(43) "Unknown column 'voltageme5' in 'field list'" Here is the stored routine: Code: [Select] CREATE PROCEDURE `database`.`table` (IN memUsername varchar(45)) BEGIN select count(*) as total from members where username = memUsername; END Whats weird is that in the PHP code if i replace the variable with a string, it works. It's only with the variable in the call that it errors out like that. I'm new to this stored procedure thing so I'm sure I'm missing something stupid. Hi Everyone, I have this php page that runs couple of MS SQL stored procedures to fetch me values from SQL Server, however I have run into a problem where not more then 2 stored procedures are executed at same time. For instance below mentioned code only fetches me values for 1st and 2nd SP's. If I need values from the 3rd stored procedure then I would have to comment either one of the first two stored procedure. Can someone please tell me what is that I am doing wrong. I am relatively new to PHP, so please be gentle. Any help would be highly appreciated. Thanks. <?php if($conn = mssql_connect('host', 'user', 'pass')) echo 'Connected to SQLEXPRESS<BR>'; if(mssql_select_db("database",$conn)) echo 'Selected DB: SomeDatabase<BR>'; $variable1=something; $sql_statement = mssql_init("stored_procedure1 '$variable1'", $conn); $result=mssql_execute($sql_statement); $x=0; while ($row = mssql_fetch_assoc($result)) { $column2[$x]= $row['column2']; $column1= $row['column1']; $x++; } echo "Value 1: $column1 </br>"; echo "Value 2: $column2[0] </br>"; echo "Value 3: $column2[1] </br>"; echo "Value 4: $column2[2] </br>"; echo "Value 5: $column2[3] </br>"; echo "Value 6: $column2[4] </br>"; echo "Value 7: $column2[5] </br>"; mssql_free_statement($sql_statement); $sql_statement = mssql_init("stored_procedure2 '$variable1'", $conn); $result=mssql_execute($sql_statement); $x=0; while ($row = mssql_fetch_assoc($result)) { $someval1[$x]= $row['somecolumn1']; $someval2[$x]= $row['somecolumn2']; $someval3= $row['somecolumn3']; $someval4= $row['somecolumn4']; $someval5= $row['somecolumn5']; $someval6= $row['somecolumn6']; $x++; } echo "Something1: $someval1[0]</br>"; echo "Something2: $someval3 </br>"; echo "Something3: $someval2[0] </br>"; echo "Something4: $someval4 </br>"; echo "Something5: $someval6 </br>"; echo "Something6: $someval5 </br>"; mssql_free_statement($sql_statement); $sql_statement = mssql_init("stored_procedure3 '$variable1'", $conn); $result=mssql_execute($sql_statement); $x=0; while ($row = mssql_fetch_assoc($result)) { $somevaluecheck= $row['somecolumncheck']; $x++; } echo "SomethingCheck: $somevaluecheck </br>"; mssql_free_statement($sql_statement); ?> Hello, Here's my system. Once a user is successfully logged in, a new instance of a User class is created. The constructor of this class grabs the details of the logged-in user from a database and stores them inside properties in the User class. The problem is, obviously I'd want to access these properties from any page I require them to be able to display user data, so I looked into storing the User object in a Session. When I tried implementing this, I ran into a bunch of errors and I couldn't figure it out. Here's an example: After a user has logged in, I had the following code: Code: [Select] $_SESSION['user'] = new User($this->username); I was under the impression that this assigns a user object to a session. But it's not working as I receive this error: Quote Notice: Undefined index: user in ../v2/admin/index.php on line 18 Then on the page I want to display the name of the current user logged-in, I had this code: Code: [Select] $_SESSION['user']->get_Name(); But then I get this error: Quote Fatal error: Call to a member function get_IP() on a non-object in ../v2/admin/index.php on line 18 Can tell me what I have to do, to make this work? Thanks. How can I run php code that is stored in a database? I have my pages created by grabbing the contents of a pageBody mySQL table cell, but some pages require further php to be able to display correctly. For example, I have a players page, which will list all players, and some information about them. The players and information is all saved in a players table in my database (separate to the pages table where pageBody is stored). I use simple php to grab all the players and format all of their information so it can be displayed on the page. This is the flow of information that I would like: User clicks on players page browser loads content page (this is a template page), and grabs the pageid from $_GET browser then reads pages table in database to get the pageBody associated with the pageid The pageBody will contain more php, which will run the players script to retrieve the list, and display Doing it the above way will make it much easier to extend the website to include more types of pages that has to run additional php scripts. The only way I can think of this working is by doing this: user clicks on players page browser loads content page, grabs pageid from $_GET browser checks the pageid for the one associated with players (hard coded into the php script) browser then loads the players.php script instead of going to the database This above way means that I will need to edit the index.php page everytime I add a new list type (example, coaches, volunteers etc). Anyone have any suggestions? I know my question is long, but I was finding it hard to explain it in an easy to understand way, but I'm still not sure if I have :S. Cheers Denno I am trying to make a setup file for a website I'm developing, and am having the database tables and stored procedures created automatically. However, I'm having issue getting the stored procedures to be created. Here is my code: Code: [Select] $db->Q(" DELIMITER $$ CREATE PROCEDURE `Database`.`Procedure_Name`(in sp_uid mediumint(20) unsigned, in sp_user varchar(15), in sp_pass varchar(20), in sp_email varchar(30)) BEGIN Insert Into Table Values (sp_uid, sp_user, md5(sp_pass), sp_email, '1', '1', '0'); Select true; END$$ "); Assume that the "$db->Q()" works just fine, as I'm having issues no where else with it. This automatically connects to the database and runs a query with whatever is inside the "()". The tables are being created just fine, but no stored procedures are being created. I've tried everything I can think of, and googled my question many different ways without finding an answer or work-through. Does anyone know what I am doing wrong? Thanks in advance. I am writting a php function that uses mysql to get user data - pretty common, right Well, my issue is that I need to run a check in my file system.

This text file is encrypted on the server HD. Upon initial entry into the page, the user enters an encryption/decryption KEY and the encrypted file is decrypted to clear text and it is available for viewing. I have some parameters that I store in PHP session variables. I do this since various subsequent actions by the user will require these parameters. The code is written and the whole process seems to work well. Since the info in these session variables is sensitive, I need to understand WHERE they are stored. I know that it is a file on the HD, but after hours of reading the PHP Manual on sessions, I am not finding where (HD directory) that storage is. I have a typical shared hosting account for my web site. Mostly I want to discover is, are the session variables in y User/file hierarchy, or are they stored in a system area where the PHP is installed. Whew. Sorry this was so long.
