    three arrays in 1 foreach loop

    I can not fix this script, because the output is not in sync. I have 3 arrays. 1) present column names. 2) prefix (fixed name). 3) suffix (uniqid value). Can someone explain how exactly I should create a foreach loop in a foreach loop with 3 arrays and fetching the field value from the get_result command as the the value it is related to. This would result in: <---->Present Column Name <-----> New Column Name <---->value1 <--------------------------------> value1_abcd <---->value2 <------------------------------> value2_abcd etc. <?php $prefix_arr = array( 'col_a' , 'col_b' ,'col_c' , 'col_d', 'col_e' , 'col_f' , 'col_g' , ) ; $col2 = uniqid(); $suffix = substr($col2, 5, 11); $servername = "localhost"; $username = "userx"; $password = "pass12345"; $dbname = "test_database"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $stmt = $conn->prepare("SHOW COLUMNS FROM table_xyz"); $stmt->execute(); $res = $stmt->get_result(); $pres_colname = $res; // var_dump($prefix_arr); foreach ($prefix_arr as $los_ele){ $prefix = $los_ele; // var_dump($prefix); // var_dump($suffix); $col_new = $prefix."_".$suffix; //var_dump($col_new); foreach ($pres_colname as $val){ $col = $val['Field']; // var_dump($col); ?> <br><input type="text" value =" <?php echo $col; ?>"><input type="text" value ="<?php echo $col_new;?>"> <?php $stmt = $conn->prepare("ALTER TABLE `table_xyz` CHANGE COLUMN `$col` `$col_new` VARCHAR(30) NOT NULL;"); $stmt->execute(); } } //$stmt->close(); $conn->close(); ?> The complicated thing this time is that I need the exact 'Field' value which is an output of get_result, so I can not fit it in.

    foreach loop with list / array

    My goal is to loop with foreach through two variables. So I found this script; <?php $abc = array('Mark','Laura'); $add = array('cocktails','champagne'); $array = array($abc,$add); foreach ($array as list($arr1, $arr2)) { // echo '<br>'; echo '<br>'; echo $arr1; echo '<br>'; echo $arr2; } But the output is not wat is desired. It says: And I would rather have: Is there any function / command in the php array reference to do this or should other code be used?

    Meaning of this error code

    I want to create a condition for my script. It starts with reading an array, this array can be unlimited, at least 4 up to 40 elements. These elements contain 2 variables. I figured out foreach is a better solution than switch (which I use now) In the next example (simple version of my above purpose) I show what I indicate. <?php $elements = array('Volvo', 'Honda', 'Ford'); ?> <form method="post"> <select name="menudrop"> <?php foreach ($elements as $value) : ?> <option value="<?php echo $value ?>"><?php echo $value ?></option> <?php endforeach; ?> </select> <input type="submit" value="submit" /> </form> <?php if (in_array($_POST['menudrop'], $elements)){ echo 'Clients enjoy eating a ' . $_POST['menudrop']; } ?> The problem is an error. The line with the error is: if (in_array($_POST['menudrop'], $elements)) what exactly does this error mean? The script is running and all things are executed like I intended, but I still get an error message at the screen. Notice: Undefined index:

    php array help

    Dear reader, On my own server I created the following code that is working perfectly: $items = []; foreach ($rows as $row) { $items[] = [ "item" => $row["item"], "brand" => $row["brand"], "number" => $row["number"], "price" => $row["price"], "start" => $row["start"], "end" => $row["end"], "shop" => $row["shop"], "location" => $row["location"], "link" => $row["link"] ]; } However my hosting party is not supporting php 5.4 and therefor I transformed the code in: $items = array(); foreach ($rows as $row) { $items = array("item" => $row["item"], "brand" => $row["brand"], "number" => $row["number"], "price" => $row["price"], "start" => $row["start"], "end" => $row["end"], "shop" => $row["shop"], "location" => $row["location"], "link" => $row["link"] ); } and now I am getting the error msgs: "Uninitialized string offset: 0". Does anyone knows what I am doing wrong? Thanks inadvance for your help!!!

    Foreach Loop

    Hello, I'm stuck at a piece of code, I'm hoping any one could help me further.Here is the idea and the problem: I want to send a mail with a personal touch. The receivers name etc. Thus I had this idea: Get all the ID's out of the database (mysql).With a foreach loop walk trough it. Foreach ID get the remainder of the needed info from the DB,Put them in place.And mail. Thus every one gets his own name in his inbox. I'm hopelessly stuck at the part where I ONLY get the ID's out of the DB and let the foreach run trough them.The sending works and I DO get the ID's out of the DB and to display them with a While loop. Script: $QueryDB = mysql_query("SELECT * FROM Registration");$ResultDB = mysql_fetch_array($QueryDB);foreach($ResultDB as $PersID){ //1) Get email. //2) Get name. //3) send mail.} (Its a quick and smaller rewrite of what I had before. Before the rage quit that is.I'm not that great of a programmer, but trying to get around and learn more by doing things like this!) Any one got a hint, snippet of code or another way to do it?Thank you in advance.
