PHP - What Does This Type Of Array Means ?
hello friends
what does this type of array means ? $data[] = $row; Similar TutorialsIs there a way to find out what the array type is? Example: Code: [Select] $array1 = array('red', 'pizza', '14'); $array2 = array('color' => 'red', 'food' => 'pizza', 'age' => '14'); if(is_recursive($array1)){ return TRUE; } else if(is_multidimensional($array2){ return TRUE; } else { return FALSE; } Hi friends how does this types of array operate ? pls help, I am repeatedly facing this code but my brain can't hold, i am familiar with multi dimensional array but what are these ? $data[$row['id']] $options['data']=$row[0]; Can anyone let me know what I am doing wrong. I am sure it will (after the fact) be obvious, but I don't see it right now. Wish to remove all array elements which do not implement ValidatorCallbackInterface. Thanks
<?php
interface ValidatorCallbackInterface{}

I have a Windows-style ini file that contains entries as such:
[Timers] Timer(1)=50 Timer(2)=30 Timer(3)=20 The entries represent an array of 3 different timers Apparently parse_ini_file can't deal with the () format. Is there any way to use this format ini file without having to change how arrays are designated? I have a dropdown list which have some elements. I want to get all the elements of the dropdown list into a variable of type array. Any Idea??? Not sure how to find what is causing my issue here, I'm running smarty which gives me this error if I switch PHP version to 7.4 (was on 7.3) : - Quote
ERRNO: 8 The line the error refers to is this : -
<p class="cart_del_info_box_text"><i class="fa fa-exclamation-triangle" aria-hidden="true"></i> <span class="cart_del_info_box_message"><?php echo $_smarty_tpl->tpl_vars['cart']->value->mDelivery['cartdeliverymessage'];?>
How do I go about finding which file has the actual problem? Thanks for any pointers. CMS: PHP-Fusion version 9.03.110, PHP version: 7.4.16, MySQL Server Version: 5.7.33-log, DB Driver: PDO MySQL My own support people at PHP-Fusion main site have been unable to help me with this problem and I'm hoping for some new eyes and new input on this error. First of all my script works perfectly fine and outputs the result desired. I know that my script is not using PDO prepared statements and I am not prepared to modify it to do so because too much would have to be changed. And I'm not fluent on PDO. My script is an event calendar and can be seen at this url: https://windy.whisperwillow.net/grims_blog/index.php The error only occurs 3 times on 3 lines.

Well I could not add comments to the posted script. These 3 lines of the db query area give the error in my error log: 1) $stuff1 = $data['post_id'] ? $data['post_id'] : ""; /* Trying to access array offset on value of type bool */ 2) $stuff2 = $data['post_title'] ? $data['post_title'] : ""; /* Trying to access array offset on value of type bool */ 3) $stuff3 = strtotime($data['post_date']) ? strtotime($data['post_date']) : ""; /* Trying to access array offset on value of type bool */ I know I am asking a lot for help on older code but would really appreciate it if someone can take a look. Edited April 19 by OldGrimClarify error lines Hi, WHAT: So I cannot for the life of me figure out why I'm getting this error. I'm trying to create a function that will display the user information from the database in a table but I have like a ton of these errors on the page and I don't know whats wrong. STEPS TO RESOLVE: So I've gone over my code a bunch of types to make sure that all the variables and what not were spelled correctly and as far as I can tell they are. I've also googled this issue to see if I can find a solution but none of them are very helpful. I honestly don't know whats wrong so kinda hard to find ways to resolve an issue, I don't even really know what this error means. THE CODE: This is where I put the function into action
<?php
display_table(
array(
"id" => "Id",
"emailaddress" => "Email",
"firstname" => "First Name",
"lastname" => "Last Name",
"salesperson" => "Salesperson",
"phonenumber" => "Phone Number",
"extension" => "Extension",
"type" => "Type"
)
);
?>
//This is the function
<?php
function display_table($fields, $data, $rows, $page){
if(isset($_GET['page'])){
$page = $_GET['page'];
} else {
$page = 1;
}
$firstRecord = ($page - 1) * ROWS_PER_PAGE;
$pageNumbers = ceil($rows / ROWS_PER_PAGE);
echo '<div class="table-responsive w-75 mx-auto py-3">
<table class="table table-dark table-bordered table-sm">
<thead>
<tr>';
foreach($fields as $key){
echo '<th class="py-2">' . $key . '</th>';
}
echo '</tr>
</thead>
</tbody>';
$keys = array_keys($fields);
for($record = $firstRecord; $record < $firstRecord + ROWS_PER_PAGE; $record++){
$row = $data[$record];
echo '<tr>';
for($recordCount = 0; $recordCount < count($keys); $recordCount++){
$column = $keys[$recordCount];
echo '<td class="py-2">' . $row[$column] . '</td>';
}
echo '</tr>';
}

</table';

Any help/advice would be really appreciated hi, very strange issue. when I create test e-mail or I will forward the specific e-mail, the script works correctly - saves attachment into server disk. now, when I configure to check another mailbox, it gives me error: Num Messages 11 Fatal error: Cannot use object of type stdClass as array in /test/emailattach/index.php on line 34 index.php: Code: [Select] <?php $mbox = imap_open("{mail.server.com:143}", "email@email", "XXX") or die('Cannot connect to mail: ' . imap_last_error()); // make connection with mailbox and check # messages if ($hdr = imap_check($mbox)) { echo "Num Messages " . $hdr->Nmsgs ."\n\n<br><br>"; $msgCount = $hdr->Nmsgs; } else { echo "failed"; } $overview=imap_fetch_overview($mbox,"1:$msgCount",0); $size=sizeof($overview); // get message info for($i=$size-1;$i>=0;$i--) { $val=$overview[$i]; $msg=$val->msgno; $from=$val->from; $date=$val->date; $subj=$val->subject; $seen=$val->seen; $from = ereg_replace("\"","",$from); // Check for attachements and store them $struct = imap_fetchstructure($mbox,$msg); $contentParts = count($struct->parts); if ($contentParts >= 2) { for ($ix=2;$ix<=$contentParts;$ix++) { $att[$ix-2] = imap_bodystruct($mbox,$msg,$ix); } for ($k=0;$k<sizeof($att);$k++) { if ($att[$k]->parameters[0]->value == "us-ascii" || $att[$k]->parameters[0]->value == "US-ASCII") { if ($att[$k]->parameters[1]->value != "") { $FileName[$k] = $att[$k]->parameters[1]->value; $FileType[$k] = strrev(substr(strrev($FileName[$k]),0,4)); } } elseif ($att[$k]->parameters[0]->value != "iso-8859-1" && $att[$k]->parameters[0]->value != "ISO-8859-1") { $FileName[$k] = $att[$k]->parameters[0]->value; $FileType[$k] = strrev(substr(strrev($FileName[$k]),0,4)); $fileContent = imap_fetchbody($mbox,$msg,$file+2); $fileContent = imap_base64($fileContent); $localfile = fopen("$FileName[$k]","w"); fputs($localfile,$fileContent); fclose($localfile); } } } } imap_close($mbox); ?> Could there be some encoding issue? with thanks, Margus It's not PHP, but if anyone could tell me what that means and how I can edit it I would be eternally grateful. <Directory /var/www/vhosts/webaddress.co.uk/httpdocs> RMode config RUidGid (username) psacln </Directory> Can you please tell me what each of these lines of code means?

{
$connection = 'NONSSL';
}
be grateful if somone would tell me what it means, i looked online but could not find the symbol
