PHP - Php 7.4 & Text: Trying To Access Array Offset On Value Of Type Null

First off, what are the names for the types of arrays?

What do you call an array that uses integers for the key?

I think when the key is text it is called an associative array?

Anyways...

 

Is there a way to create an array where they keys are integers, but you are defining the first entry?

I would like my array to either start with a "1" or maybe "1001".

How do I do that?

 

Hi,
I know the problem that I am having is related to the change in PHP5 about strings and arrays, however I do not understand why my script is affected. It seems like I am not trying to add more variables to an array. I do not success in order solve the problem.
Help me please:





// Build View Array
    if ($view_result!=false) {
        $i=0;
        while ($view_row =@ mysql_fetch_array($view_result)){
            $i++;
            $view_rows[$i] = $view_row;

            // build view_comments array
            if ($viewcomments=="yes") {
                $sql = "SELECT * FROM blog_comments WHERE nBlogId=".$view_row["nIdCode"]." ORDER BY nIdCode DESC";

                $result = mysql_query($sql,$con);
                if ($result!=false){
                    $j=0;
                    while ($comment_row =@ mysql_fetch_array($result)){
                        $j++;
                        $view_comment_rows[$i][$j] = $comment_row;
                    }
                }
            }
        }
    } else {
        $problem = "2";
    }

    // increment view counter for either the single blog being shown
    // or ALL blogs being shown
//The problem is here   
if ($view_rows[1]["nIdCode"]!="" && strpos($_SERVER["PHP_SELF"],"admin.php")==false){
        if ($viewmode=="single"){
            $blogid = $view_rows[1]["nIdCode"];
            $sql = "UPDATE blog SET nViews=nViews+1 WHERE nIdCode=".$blogid;
        } else {
            for ($i=1;$i<=count($view_rows);$i++){
                $blog_array[$i] = $view_rows[$i]["nIdCode"];
            }
            $blogids = implode(",",$blog_array);
            $sql = "UPDATE blog SET nViews=nViews+1 WHERE nIdCode IN (".$blogids.")";
        }
        $result = mysql_query($sql,$con);
        if ($result==false){
            print "<li>Problem with SQL<br>[".$sql."]</li>\n";
        }
    }
}

Error message :-

Error is on this line "$data = file_get_contents('http://xxx.com/'.$city[1][$k].'');"

Using the following code:

$qwe = array('a','b','c','d','e');

{

$asd = rand(0, sizeof($qwe)-1);

}

gives the following error:

Notice: Undefined offset: <offset> in <directory>\<file>.php on line 7

I'm getting an error: Undefined offset: 1 in… I'm trying to display a 2D array after filling it. It displays fine if I echo it while it's being made, but after it is not working.   I'm making a pyramid solitaire game and am trying to set up the pyramid of cards. There are 7 arrays, each with a set amount of cards in them. The first array only gets one cards while the last array gets seven. This makes it like a pyramid. All the indexes that don't get a card are set to 0. So it looks like this where the 1's are cards:   1 0 0 0 0 0 0 0 ​1 1 0 0 0 0 0 0 ​1 1 1 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 1 0 0 0 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1   The display2Darray function is what is causing the error. Specifically this line:

if($array[$i][$j] == 0) 

Heres my main code:

<?php
    include_once "pyramidCard.php";
    include_once "pyramidDeck.php";
    
    $theDeck = new Deck();
    $pyramid = array(array(), array(), array(), array(), array(), array(), array());
    $size = 7;

    $theDeck->shuffleCards();
    
    makePyramid($pyramid, $size, $theDeck);
    display2Darray($pyramid, $size);
    
    
    //************************
    //      FRUNCTIONS       *
    //************************
    
    function makePyramid($array, $size, $deck)
    {
        $row = 0;
        for($i = 0; $i < $size; $i++)
        {
            for($j = 0; $j < $size; $j++)
            {
                if($j > $row)
                {

            }
            $row++;
        }

Hi, when I run my script I get the following error message. These are array variables I am passing into the playerAttack function. I can't figure out what is wrong it looks fine to me. Any help greatly appreciated. Thanks. Derek

Earlier it was giving an error without  if (is_array($link)) {

Code: [Select]
Fatal error: Cannot use string offset as an array
However after adding it, it wont go to /hospitals-in/District-of-Columbia which is $link[1][1];

Can someone please point me my mistake

I'm trying to develop a Joomla plugin for 1.6/1.7 and from what I've read, future versions are supposed to be php E~STRICT compliant. I know that doesn't mean I have to fix this since it is just a notice, but I am curious how one would hide the error.

Code: [Select]
$task_array = explode('.', JRequest::getVar('task')); # Splits article.save
$task = $task_array[1]; #This is line 58

I know it happens because $task_array is empty, but how can i wrap that in something to stop this Notice error? I've tried !empty() but that doesn't work.

I have an array which can be empty; in this case, I get error. I want to skip when the array is empty.

When calling the array from file, I use the following code if (file_exists($array_file)) { 
"the doing code"
} else {
echo "File does not exist";
}


How I should use this If Else condition when array comes from a string like  $test_array = explode(', ', $examplestring, -1);

And i'm using this code to remove but no success

print_r(array_values(array_filter($cronograma)));

 

Any help please

 

Thanks

The title makes it sound more complicated than it is.

I have a recurring function that searches for a specific value in a multi-dimensional array. When it finds it, it returns an array of the index.

For example, if it found the value at $array[1][4][2][0], it would return an array like this:
[0]=>1
[1]=>4
[2]=>2
[3]=>0

Here's the function.
Code: [Select]
<?php

// Other Code

/**
 * Find's the parent of an item
 * Unfortunately, it takes a bit more work than just using the loudspeaker at a grocery store
 * @param int $parent The parent to be searched for
 * @param array $array 
 * @param array $cur_index
 */
private function findParent($parent, $array, $cur_index)
{
    for($i = 0; $i < count($array); $i++) { // Search the array
        if($array[$i]['id'] == $parent) { // If the parent is found
            $cur_index[count($cur_index)] = $i;
            return array(true, $cur_index);
        }

        if(count($array[$i][1]) > 1) { // Call findParent again to search the child
            $cur_index[count($cur_index)] = $i;
            $found_in_child = $this->findParent($parent, $array[$i], $cur_index);
            if($found_in_child[0]) {
                return $found_in_child;
            }
        }
    }
    
    return array(false); // Return no matches
}
I need to be able to call that index using the keys from the key array (as we will call it). How can I do that?

Thank you in advance for your help.

Hi,

Am hoping someone can please help.

I've the following code:

$chosen_methods    = WC()->session->get( 'chosen_shipping_methods' ); 
$chosen_method     = explode(':', reset($chosen_methods) );

The first line returns the warning:
"Warning: reset() expects parameter 1 to be array, null given in"

I've tried the following:

$chosen_method     = '';
$chosen_method     = NULL;
$chosen_methods     = array();

Sadly, none have worked. What am I missing?

Thanks

Hi, I have results from a MySQL table column which does an echo into a table cell, but some of the results from the table column is be empty, so is there a way to fill in the blanks with text like "No data"?  

When I send values to the foreach they are not recorded in the array.

$x = $getProductID;
$_SESSION['pColors'] = array();

if(isset($_POST['pColors'])) {

    foreach($_POST['pColors'] as $colorKey => $RColors) {
        $_SESSION['pColors'][$colorKey] = $RColors;
    }
}

var_dump($_SESSION['pColors']);

Send date with AJAX:

                $('.addToCart').click(function(){
                    $.ajax({
                        url:""+realLink+"cart.php",
                        method:"POST",
                        data:{action:action,pColors:pColors},
                            success:function(data){
                               //alert(data);
                            }
                    });
                });
