How to fix this `Illegal string offset` error in php?

Question

I have a multidimensional array as below:

$rows[] = $row;

Now I want to create variable from looping this array. This is how I tried it:

foreach ($rows as $k => $value) {
  //echo '<pre>',print_r($value).'</pre>';
  $id    = $value['news_id'];
  $title = $value['news_title'];
  echo $title; 
}

But it produce an error as below:

...... Illegal string offset 'news_id'

This is the output of - echo '<pre>',print_r($value).'</pre>';

Array
(
    [news_id] => 1110
    [news_title] => test
    [news] => test des
)
1

Array
(
    [news_id] => 1109
    [news_title] => ශ්‍රී ලංකාවේ ප්‍රථම....
    [news] => දහසක් බාධක....
)

Can anybody tell me what is the wrong I have done?

UPDATE output for echo '<pre>',print_r($rows).'</pre>';

Array
(
  [0] => 
  [1] => Array
      (
          [news_id] => 1110
          [news_title] => test
          [news] => test des
      )

  [2] => Array
      (
          [news_id] => 1109
          [news_title] => ශ්‍රී ලංකාවේ ප්‍රථම....
          [news] => දහසක් බාධක....        
      )

Please add this to your code and put the result here: echo "<pre>" . print_r($rows) . "</pre>"; Because your syntax (array['index']) works for me. I would like to see how $rows is created. — Nic3500

Ok thanks. So $rows[0]['news_id'] does not exist. Add a check if (isset($value['news_id'])) { ... } — Nic3500

use isset function because your 0 index is empty in $row

foreach ($rows as $k => $value) {
  if(isset($value['news_id'])){
    $id    = $value['news_id'];
    $title = $value['news_title'];
    echo $title; 
  }

}

you should add check (condition) when you assign data to $rows

The error Illegal string offset 'news_id' tells that $value is a string and 'news_id' is an illegal index, this may suppress error but not explaining what is wrong or how to fix it.

0th index doesn't need to be empty, simply being a string instead of an array would suffice. Let

$rows = array('key' => array('news_id' => 'foo', 'news_title' => 'bar'), 'key1' => array('news_id' => 'foo', 'news_title' => 'bar'), 'key2' => array('news_id' => 'foo', 'news_title' => 'bar'), 'key3' => 'I am a simple string')

, then trraversing this array with a foreach loop and checking $value['news_title'] will simply fail with Illegal string offset 'news_id' .
