PHP - How Do I Print All Environment Variables (with Names And Values)?
I've googled a lot but still can't find much of a clue for how to do this (printing all environment variables in PHP that is).
I know it has something to do with $_ENV and $_SERVER but... I would be thrilled for some guidance! Best regards, Rasekamon Similar TutorialsNot asking you to troubleshoot for me but to pop in any thoughts you might have on how YOU would troubleshoot this problem.. Thanks
This is a wp site.. and generated the following error.. Notice: Undefined index: USER_AGENT in /home/luxuryrealtygrp/public_html/wp-content/plugins/LRG/Masked/Filters.php on line 31 This is what line 31 that is being called out: Line 31: function lrg_masked_field($false, $field_name){ if(is_user_logged_in() || stripos($_SERVER['USER_AGENT'], 'google') !== false || stripos($_SERVER['USER_AGENT'], 'yahoo') !== false || stripos($_SERVER['USER_AGENT'], 'bing') !== false){ return false; }
Just looking for ideas that might help to chase this down..
Edited December 17, 2020 by tommytx What's the best way to cache things on the server? I've found some SetEnv things but this all seems to be a single key/value.
I'd like to cache an array of things that I can access later. Right now it's cached in $_SESSION which is fine, but still there's overhead on every first-time visitor to a site. Is there a way to add something to $_SERVER or elsewhere that ALL visitors to a website will ultimately be able to access?
I guess I want something like web.config in C#, where the first time a page is visited, the "app starts", as it were, and those things are now in cache on the server.
What's the best way to do this?
What I have done in the past is created a conn.php file, used as an include, when I wish to connect to my DB. As a security measure, rather than have my connection info in a file that could potentially get accessed by unauthorised users, I read that I could use environment variables and store the database connection string values i.e username, password etc for retrieval. Can anyone offer some guidance on going about this? Thanks I am by no means a security expert, but I would like to know if storing MySQL database information in an environment variable would be a good or bad idea. What are your thoughts? I am building a website that uses session variables extensively. The site is getting a little complicated, and I am starting to lose track of which session variables are assigned, and what their values are. Is there some way where I can create a piece of code that will display all of the existing session variables and their values? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=318312.0 Hi all, I have the following MySQL insert query: Code: [Select] $insert= mysql_query ("INSERT INTO tablename (column1,`".$EXPfields."`) VALUES ('$something','".$EXPvalues."')"); where $EXPfields is an array of table-field-names and $EXPvalues is an array of table-field-values. Now I want to write an equivalent query, but using UPDATE instead of INSERT INTO, but I don't want to write out all the field names/values separately, but again want to use $EXPfields and $EXPvalues. So something like this: Code: [Select] $update = mysql_query ("UPDATE tablename SET (column1,`".$EXPfields."`) = ('$something','".$EXPvalues."') WHERE .... "); Is this possible? If so, what is the proper syntax? Thanks! Hi, I have a database with numbers/dates etc stored. I am creating a multilingual site, in both English and Burmese/Myanmar. Burmese/Myanmar has a different alphabet - a bit like Chinese/Thai. The database is set up nicely to allow text translations, but I am having a problem with numbers. How would I go about printing a number/date in Burmese script from a datebase stored as numeric values - i.e.int?? Database etc. is all utf8. Thanks. Hi, I have a string with the value of { "success": true, "delivered": true, "contactDetailsRequired": false, "message": "Signed For by: D ANDERSON ", "signature": "https://webservices.thedx.co.uk/PodImage/ImageHandler.ashx?tn=906732192165", "date": "21-07-2020", "serviceLevelName": "Consigned", "time": "13:33:19", "trackedProductName": "DataExchange" } How do i go about placing the values into variables so for example: $success = "true"; $delivered = "true"; $message = "Signed for by: D ANDERSON"; etc.... My mind has gone blank and im having one of those days, any help would be greatly appreciated. Thanks Hi all, I am having some trouble with a script.. all works fine except for the calculation part. It isn't adding up, but the reason for this is because when I echoed all the variable it seems that they are blank, the problem is I can't figure out why? <?php # you don't display errors on in-use scripts, do you? ini_set('display_errors',0); error_reporting(E_ALL|E_STRICT); class webPoll { # makes some things more readable later const POLL = true; const VOTES = false; # number of pixels for 1% on display bars public $scale = 2; public $question = ''; public $answers = array(); private $header = '<form class="webPoll" method="post" action="%src%"> <input type="hidden" name="QID" value="%qid%" /> <h4>%question%</h4> <br /> <ul>'; private $center = ''; private $footer = "\n</ul>%button%\n</form>\n"; private $button = '<p class="buttons"><button type="submit">Vote!</button></p>'; private $md5 = ''; /** * --- * Takes an array containing the question and list of answers as an * argument.

Many thanks, Greens85 Hi I am adapting Jeffery Ways Mysql class to accept multiple where statements however I have got stuck on the final hurdle. It is when I try to do the bind_results() and I pass in the parameter types and the parameters. Here is that part of the code: if ($this->_where) $values = array_values($this->_where); $str = "'"; $str .= implode('\', \'', $values); $str .= "'"; // echo $str; $count = count($this->_where); foreach($this->_where as $key => $value){ $key = $value; } $user = 'matt25'; $pass = '6722853cacc4a9649dc75abc852f23c35b1f75cb'; $stmt->bind_param($this->_paramTypeList, $user, $pass); } It works how it is by setting the parameters as variables, but that obviously isn't practical. as you can see I also tried to make a string with the values from the array which brought up the error: Warning: mysqli_stmt::bind_param() [mysqli-stmt.bind-param]: Number of elements in type definition string doesn't match number of bind variables in C:\wamp\www\trick_tips\admin\includes\MysqlDb.php on line 260, the same as when I try to put the array into there. So I need some way of setting each value in the array as a variable to then put into the function, or another Idea that I have completely missed. Any help would be much appreciated. Cheers, Matt What would be the correct way to use returned sql results as variables. I have tried the way in my script, but Im unsure of how I can echo just one of the $nt variables further on in my script. $code = $_GET['postcode']; $shortcode = substr($code,0,2); $query =mysql_query ("SELECT email FROM treesurgeons WHERE postcode like '%" . $shortcode . "%' ORDER BY companyName LIMIT 3"); echo mysql_error(); echo "<p>The email addresses you have requested are;</p>"; while($nt=mysql_fetch_row($query)){echo "$nt[0],$nt[1],$nt[2]<br>";} echo "<p>please use $nt[2] if you ever want to contact me</p>"; //this line doesnt work for me ?></body></html> is there is a way to assign variables such as; $nt[0] = $firstemail $nt[1] = $secondemail $nt[2] = $thirdemail this way I could use each of my sql values, just as I would any other variable? $username = $_POST['uid']; $email = $_POST['mail']; $password = $_POST['pwd']; $passwordRepeat = $_POST['pwd-repeat']; $date = $_POST['date2']; $stream = $_POST['relationship']; $sql1 = "INSERT INTO users (uidUsers, emailUsers, pwdUsers, relationship) VALUES (?, ?, ?, ?);"; $sql2 = "INSERT INTO Family1 (username, application_filed, relationship) VALUES (?, ?, ?);"; $sql3 = "INSERT INTO Family2 (username, application_filed, relationship) VALUES (?, ?, ?);"; mysqli_query($sql1, $conn); mysqli_query($sql2, $conn); mysqli_query($sql3, $conn); $stmt = mysqli_stmt_init($conn); if (!mysqli_stmt_prepare($stmt, $sql2)) { header("Location: ../signup.php?error=sqlerror"); exit(); } else { mysqli_stmt_bind_param($stmt, "sss", $username, $date, $stream); $result = mysqli_stmt_get_result($stmt); if ($row = mysqli_fetch_assoc($result)) ($username==$_SESSION['uid'] and $stream =='nursing'); mysqli_stmt_execute($stmt); } if (!mysqli_stmt_prepare($stmt, $sql3)) { header("Location: ../signup.php?error=sqlerror"); exit(); } else { mysqli_stmt_bind_param($stmt, "sss", $username, $date, $stream); $result = mysqli_stmt_get_result($stmt); if ($row = mysqli_fetch_assoc($result)) ($username==$_SESSION['uid'] and $stream =='doctoral'); mysqli_stmt_execute($stmt); } if (!mysqli_stmt_prepare($stmt, $sql1)) { header("Location: ../signup.php?error=sqlerror"); exit(); } if (!mysqli_stmt_prepare($stmt, $sql1)) { header("Location: ../signup.php?error=sqlerror"); exit(); } else { $hashedPwd = password_hash($password, PASSWORD_DEFAULT); mysqli_stmt_bind_param($stmt, "ssss", $username, $email, $hashedPwd, $stream); mysqli_stmt_execute($stmt); header("Location: ../signup.php?signup=success"); exit(); I was wondering if someone could point me in the right direction. I have this code. They idea I had behind it is to insert values into different tables depending on variables being passed. So when user fills out a form and selects $stream="nursing" I want results to go to table 'users' and 'Family1', but not 'Family2' table. and if user selects $stream='doctoral' results should go to table 'users' and 'Family2', and not go to 'Family1' But with my query I get results go to both table and also users table. And there is no restriction to what users selects, variable $stream being passed no matter what it is. Is this the wrong way to go here? Did I completely mess up the logic? As part of my User Profile, I have a series of open-ended questions that Members can answer, e.g... Quote 1.) Why did you start your own business? 2.) If you could offer one piece of advice to other entrepreneurs, what would it be? : 10.) How do you compete against large corporations? I was leaning towards creating a many-to-many relationship like this... member -||---------0<- answer ->0---------||- question From a database standpoint this works great, HOWEVER, I just realized a big problem... If run this query... Code: [Select] SELECT response FROM answer WHERE member_id = 1; ...then I would get TEN RECORDS back and I don't know of any way to maps those to the 10 Text Boxes on the "My Thoughts" page?! (It would be a real PITA to have to create 10 separate Prepared Queries in PHP - one for each Field - to fill out my page?!) So, is there a way to keep my table structure, but push the 10 records from above into 10 separate variables so I would have something like $response1, $response2,... $response10 ?? Thanks, Debbie Hi I am having issues with the following code. I cannot get the table to produce a subtotal multiplying the value of 'ITEMQTY' which is a text field in the form in which the user enters by the 'ITEMPRICE' field which value is located in a text document. <h1>SHOPPING CART</h1><img src="images/cart.png" alt="Cart" width="100" height="100"/> <a href="browse_index.php">CLICK HERE TO CONTINUE SHOPPING</a> <?php if(isset($_POST['submit'])) { $itemname = $_POST['h1']; //echo $_SESSION['itemname'][$itemname]; unset($_SESSION['itemqty'][$itemname]); unset($_SESSION['itemprice'][$itemname]); unset($_SESSION['itemname'][$itemname]); } echo "<br/><br/>"; echo "<table border='8' cellpadding='10' >"; echo "<tr><th>Name</th><th>Quantity</th><th>Price</th><th>Subtotal</th></tr>"; foreach($_SESSION['itemname'] as $key => $value) $subtotal = ($_SESSION['itemprice']*($_SESSION['itemqty']; { echo '<tr> <td>'.$_SESSION['itemname'][$key].'</td> <td><input type="text" name="t1" value='.$_SESSION['itemqty'][$key].'></td> <td>'.$_SESSION['itemprice'][$key].'</td> <td>'.$_SESSION['h2'][$key].'</td> <td><form id="f1" method="post" name="f1"><input type="submit" name="submit" value = "delete"><input type="hidden" name="h1" value='.$key.'></td> </tr> <tr><form id="t1" method="post" action="summary.php" name="t1"><input type="submit" name="order" value="SUBMIT ORDER"></tr>'; } echo "</table>"; ?> Hello there
After a few years of spending less and less time coding, I've got a lot of catching up to do. Back when I left I usually would run without classes. Now this is a big deal for me today.
I do understand the concept of classes and already did some working models, mostly from my learning process.
Now here is what is bothering me:
<?PHP class database { // Variables public $test; // Constructor public function __construct() { $test = "4"; } // Functions // public function test() { var_dump($this->test); } } $test = new database; $test->test(); ?>Wether I run this script on itself, nor through another file, this does work. What i get is: NULL The constructor does run, I did an echo inside it. Also it does not matter if the variable is public, private or protected - it will be always NULL. Error_reporting is on E_ALL, does not show any errors. What have I overlooked? Hey guys,
I'm using the following pagination script from a website I found. I'ts basically a pagination script that takes data from a MySQL database and displays a certain number of sets before placing the next set on a new page.
This script works great if I substitute a static value for the data I want returned but If the request is stored in a $POST variable like from an HTML form the data refuses to paginate. It will render the first set of data but will not paginate the rest and only shows blank pages
I'm thinking it has something to do with the $POST variable not being set or carrying over to each page but I'm not sure.
I truly appreciate the help!

Edited November 19, 2018 by phpsaneHi,
I hope this belongs to the right sub-forum.
I'm gonna be on the move for quite some time, and I was wondering if there was an [almost] ideal portable PHP development environment, which I can treat just like the non-portable counterpart, which will include using Composer, Laravel, etc.
With a little research I found http://zwamp.sourceforge.net/ and http://www.codelobster.com, but I'm not sure how efficient they are.
Any of you guys use this approach?
Thanks.
