get first object from result array php

Question

I have view file on my app there is code array I want to get first object of that array without going in loop.

    <?php
$result = array_chunk($products->result_array(), 3);

foreach($result as $products){  ?>
    <table style="width:100% style="page-break-after:always;"   >

    <tr>

    <?php 
    foreach($products as $productArray){
        $product = (object) $productArray;
        echo '<td>';
    ?>

    <div style="width: 100%; height: 210px;  border: 1px solid #dddddd; margin: auto 5px 5px 0; padding: 5px;">
            <div class="box-header">
                <p class="box-title"><FONT SIZE=12><?php echo $product->product_name; ?></FONT></p>
            </div>
            <div style="height: 100px; text-align: center;">
                <?php echo '<img src="'.'uploads/'. $product->photo.'" class="img-responsive" style="height:100px !important; width: 150px !important"  />'; ?>
            </div>

            <div style="clear: both"></div>
            <table class="table table-responsive">
                <tr>
                    <th><FONT SIZE=12>ID</FONT></th>
                    <td><FONT SIZE=14><?php echo $product->product_id; ?></FONT></td>
                </tr>

$result is array of object I'm getting from a form. In below you can clearly see I'm chunking it to 3 more array and looping though individual objects and getting their details to html for example.

 <tr>
                    <th><FONT SIZE=12>ID</FONT></th>
                    <td><FONT SIZE=14><?php echo $product->product_id; ?></FONT></td>
                </tr>

I want to get the first object details let's say want get $product->product_name of first object of result array without going in loop how to achieve that.

here is complete view file code.

<!DOCTYPE html>
<html class="bg-black">
<head>
    <meta charset="UTF-8">
    <title><?php if(isset($title)) echo $title.' | '; ?>  Sales agent management software (SAMS) </title>

yes Abdulla is right. u should keap your view away of php codes. like $result = array_chunk($products->result_array(), 3); And u should use only if, for , echo — Sina R.

Also i think u need to check your opening and closing tags like <tr> and </tr> or <td> and </td> — Sina R.

ok man as i said u need to change your way of writing codes but about your specific question use this:

$result = array('a', 'b', 'c', 'd', 'e');
reset($array);
$first = current($array);

you can check this:

http://php.net/manual/en/function.reset.php

http://php.net/manual/en/function.current.php

But still about your way of coding. u should soon go to MVC or such ways of programming so u should separate your view and coding logics

like u may have a page like view_profile.php which is going to show user's information. in regular coding u have this:

view_profile.php:

<?php session_start();

// you check sessions to see if the user is logged in and has the right to view this page.
// like:

if ($_SESSIONS['is_user_logged_in']){
   $username=$_SESSIONS['username'];
   $name=$_SESSIONS['name'];
   // ....
}else{
    header('location: ./login.php');// if user is not authenticated u redirect to login page
    exit();// prevents the rest of codes to be shown and executed 
}
?>
<html>
<head>

<title>View <?php echo $name; ?>'s profile</title>

</head>
<body>
   <div>Name: <span><?echo $name; ?></span></div>
   ......
</body>

</html>

But in a better way u can do it like this:

you have files like

'view_profile.htm' // holds the HTML 'view_profile.php // holds the PHP logic 'inc.php' // holds some useful functions that help you in writing PHP logic

view_profile.htm

<html>
<head>

<title>View <?php echo $name; ?>'s profile</title>

</head>
<body>
   <div>Name: <span><?echo $name; ?></span></div>
   ......
</body>

</html>

inc.php

<?php

function ses_start(){
    if(!session_id()){
        session_start();
   }
}

function ses_get($key){
    ses_start();
    if(!empty($_SESSION[$key])){
        return $_SESSION[$key];
    }
    return NULL;
}

function ses_set($key,$val){
    $_SESSION[$key]=$val;
}

function is_user_loggedin(){
    ses_start();
    if(!empty(ses_get('is_user_loggedin')){
        return true;
    }
    return false;
}

function go($to){
    header('location: '.$to);
    exit();
}

//and lots of useful functions that help u connect and work with data base.

view_profile.php

<?php 

include('inc.php');

if(is_user_loggedin(){
    $username=ses_get('username');
    $name=ses_get('name');
    //...
}else{
    go('login.php);
}

include('view_profile.html); // and u call the .htm file that holds the HTML the view file)

?>

this was a simple sample of separating codes logic(php codes) from views(html tags)

and also u may search about MVC Model-View-Controller and try working with simple MVC frameworks.

your welcome but as a friend i advice you to check the rest of the answer and also the links. cause u will see that you need to separate your logic and view. - good luck
