PHP - How To Print A String That Also Contains An Array?

What I'm trying to achieve is to get a set of data from a database and then cycle through the array and add the contents of each row to a variable.  I'm trying to use $i to cycle through the array but at the moment it's just printing the first character of each set.  Any help would be great. 


$fav_products_sql = "select fav_products.product_id, fav_products.product_order, product_list.product_name from fav_products, product_list where fav_products.product_id = product_list.id";
$fav_products_rs = mysql_query($fav_products_sql, $conn);
$fav_products = mysql_fetch_array ($fav_products_rs);

while ($i < 11) {
$_SESSION['fav_products'] = "<li>" . $fav_products['product_order']['$i'] . ": " . $fav_products['product_name']['$i'] . "</li>";
$i++;
}

You can ignore my previous thread: Xpath help. I made it needlessly complicated!

Here's my problem:

My array $selected contains:
Array

)

I have the following code:
echo "<td>".$selected[0]['name']."</td>";
echo "<td>".$selected[0]['code']."</td>";
echo "<td>".$selected[0]['type']."</td>";
echo "<td>".$selected['requiredLevel']."</td>";

This line of that code does not work:
echo "<td>".$selected['requiredLevel']."</td>";

I've tried:
echo "<td>".$selected[0]['requiredLevel']."</td>";
which also does not work.

Can anyone help me figure out why?[/code]

So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : 

<?php
    $myStr = (
        "00ffff", "00cccc", "009999", 
        "007777", "004444", "001111", 
        "01ffff", "01cccc", "019999"
    );
?>

& turn it into 3 separated arrays like : 

<?php
    $myNewArrs = [
        Array1 ( 3 ), 
        Array2 ( 3 ), 
        Array3 ( 3 ), 
    ];
?>

which REALLY looks like : 

<?php
    $myNewArrs = [
        Array ( "00ffff", "00cccc", "009999" ), 
        Array ( "007777", "004444", "001111" ), 
        Array ( "01ffff", "01cccc", "019999" ), 
    ];
?>

?

Any assistance is most-definitely appreciated!

Thank you & have a great afternoon!

Dear all, 

Kindly help with this code I have written, it is not returning the array I created. It is a very small script but I have been looking for a very long time but I couldn't see why it went wrong.

$duration = 2;
$start='01-01-2019';
$month =date('n', strtotime($start));
$year =date('Y', strtotime($start));
$mon = 12-$month+1;
$remainingMonth = $duration*12;

$years_arr = array("$year");
$residue_arr = array("$remainingMonth");
$years_arr = process($remainingMonth,$year,$mon,$years_arr,$residue_arr);

print_r($years_arr); //<output

function process($remainingMonth,$year,$mon,$years_arr,$residue_arr){
    $residue = $remainingMonth - $mon;//$D$18-D20
    if($residue != 0){
        $new_year = $year+1;
        array_push($years_arr, $new_year);
        array_push($residue_arr, $residue);
        
        if($residue > 12 ){
            $mon = 12;
        } else {
            $mon = $residue;
        }
        echo "<br>";
        process($residue,$new_year,$mon,$years_arr,$residue_arr);
    } else {
        print_r($years_arr);
        return $years_arr;
    }
}//end of process(..)

The objective is to add a year to the $years_arr array and then print it put, yet I notice that nothing get's printed out. Please assist, if you need more info from my side, please do ask. Thank you very much in advance.

I am trying to break down an array to make it easier to read. An array that looks like Array ( => 0 [1] => 0 [2] => 0 [3] => 0012844 1 [4] => 37 [5] => 1 etc...) I want to display it like: Code: [Select]
[0] => 0
[1] => 0
[2] => 0
etc...
how can this be accomplished.

Hi

i have an array of 39 arrays. Only 5 are shown below so that you have an idea before i ask my question.

<?
array(39) 
{
 [0]=> array(3) { [0]=> string(18) "unit name 1" [1]=> string(9) "category name 1" [2]=> string(20) "Course 1" }

 [1]=> array(3) { [0]=> string(54) "unit name 2" [1]=> string(15) "category name 2" [2]=> string(20) "Course 1" }
 
[2]=> array(3) { [0]=> string(29) "unit name 3" [1]=> string(15) "category name 2" [2]=> string(20) "Course 1" } 

[3]=> array(3) { [0]=> string(64) "unit name 4" [1]=> string(30) "category name 3" [2]=> string(20) "Course 2" }

[4]=> array(3) { [0]=> string(57) "unit name 5" [1]=> string(24) "category name 1" [2]=> string(20) "Course 1" }

[5]=> array(3) { [0]=> string(50) "unit name 6" [1]=> string(24) "category name 4" [2]=> string(20) "Course 2" }
}


i want a php solution to print category names in table headers , unit names in table rows and course name(s) in table caption.I have tried foreach loop but how to remove duplicate entries as you can see category name 1 and 2 will become two separate headers instead of one and same is the case with Course 1 and 2.
i have googled but could'nt find any solution. i don't want to remove duplicate entries , all i want to display them once in a table as described above.

Hello,

Having a bit of a tough time understanding what is going on in my brain! 

I'm basically pulling some data from an API using CuRL, which is working fine. The structure of the data is:

[data][tickets] - tickets being an array of support tickets in the system, which then contains ticketNumber, title, content. I want to display these values in a list, I have this code currently:

  if ($err) {
    echo "cURL Error #:" . $err;
  } else {
    $return = json_decode($response, true);
    foreach($return as $key) {
      echo $key["tickets"][1]['ticketNumber']." - ";
      echo $key["tickets"][1]['title']." - ";
      echo $key["tickets"][1]['content'];
    }
  }

Which obviously returns the ticketNumber, title & content of the first support ticket in the array, but I want to loop through and display that information for each ticket! 

Can anyone advise as to where I am going wrong? I think I need to utilise the ["tickets"][x] but not sure how!

 

Thanks in advance!

Hello,   I am fairly new to PHP and I found some php code to print an array of numbers that create a combination - however, its slams all the numbers together without a space or a comma separator.   How can I separate the numbers in this array with the given code?  Ive attached a photo of the code.

 

 

 

 

Hi

I need to know how to arrange this thing looking something like an array to be able to find values from it. The problem is, I don't really even know what I am dealing with here. Wonder if you could help me out.

I have the following mess stored in a $messages variable:

{"messages":[{"message_id":2314446,"from":"441234568790","timestamp":1280703181,"text":"first text"},{"message_id":2315147,"from":"123456789014","timestamp":1280755014,"text":"another text"}],"unread":0}

and I don't know how to do the following:

I need is to get only the message text from any message that matches my wanted phone number. For example: I want to get the text value from message which from is 123456789014.

/Henry

OK so here is what I want to do. I have a bunch of strings stored in a table. The strings are like this grandparent.parent.child. some are just parent.child
What I want to do is Select all and then put them into an array.

soooo x.y.z would become $Var['x']['y']['z']
and a.b would become $Var['a']['b']

It has to be dynamic because some strings are just 2 levels, and it goes all the way up to 6 levels. I have different plans for setting the variably to something but I can handle that.

Any ideas?

Hi all,

Im so stuck on this! Cant figure out a solution...

$precip_array[0] has a value of "80" in it as a string. I need to compare it to an integer.

echo (int)$precip_array[0] returns a "0".  Ive also tried adding a 0 but that results in the same.

I did a var_dump on $precip_array[0] which returns string(17) "80"

I think 17 signifies the length of the string, but I only see 2 digits when I echo this.  Any help is much appreciated.

I have in ONE MySQL database row a string of ID's like this:

Name of Row: Values: Post IDs 10 14 52 37
And now I want to fetch those ID's explode them (by the space) and then use them as an array, like this:


$array[] = explode(" ", $query);

echo $array[0]; // 10
echo $array[1]; // 14
echo $array[2]; // 52


Is this possible, if yes how can I do this?

How can I get rid of  "Notice:Array to string conversion on line 78" error from this code?  can i get a little help please? 

This is line 78 :         $table .= $columnValue;

Basically this code's supposed to do is to group the values from grpa, grpb of datatb to 4 different categories according to their value. and as end result, category index number  of each category is put into the html table.

Thanks.

 

<?php

 include ("configd.php");

  $sql = "SELECT grpa, grpb From datatb";
  $result = $conn->query($sql);
  
  //categories
  
  $cat = [
    4 => [1, 2, 3, 4],
    3 => [5, 6],
    2 => [7, 8],
    1 => [9, 10]
];
while ($row = $result->fetch_assoc()) {
    foreach ($cat as $catKey => $catValue) {
        $columns[$catKey] = array_filter($row, function ($col) use ($cat, $catKey) {
            if (in_array($col, $cat[$catKey])) {
                return true;
            }
        });
    }

    $output[] = $columns;
}


// the output 

$table = <<<EOT
<table class='maintable'>
    <tr><th>9:10</th></tr>
    <tr><th>7:8</th></tr>
    <tr><th>5:6</th></tr>
    <tr><th>1:4</th></tr>
</table>

EOT;


foreach ($output as $row) {
    $table .= "<table class='maintable'>";

    foreach ($row as $columnKey => $columnValue) {
        $table .= "<tr>";
        $table .= "<td>";
        $table .= $columnValue;
        $table .= "</td>";
    }

    $table .= "</tr>";
    $table .= "</table>";
}




echo $table;

?>

Hello,

I have a string that contains a directory path much like: "/images/icons" and I want to take that string through a function and explode it into an array of directories that with add my directory structure array:

images icons
Then if I were to send the string "/data/documents" to the function it would append to the existing array:
images icons data documents
Here's the code that I've got thus far:
<?php

$global_structure = array();

generate_structure("./images/icons");
generate_structure("./data/documents");

function generate_structure($directory)
{
    if(!is_dir($directory))
        return false;

    $directory_structure = explode("/", $directory);

    // do something here to iterate over $global_structure and add new directories to equal to current directory path making the value an empty array.
}

?>
