Illegal String Offset Warning PHP

Illegal string offset Warning PHP

Please try this way.... I have tested this code.... It works....

$memcachedConfig = array("host" => "127.0.0.1","port" => "11211");
print_r($memcachedConfig['host']);

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

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

Warning: Illegal string offset PHP 7 foreach

You need to check whether ProdIt is 1-dimensional or 2-dimensional. In the first example, it's a single associative array, not an array of associative arrays.

$prodit = $jsonRes['prod']['ret']['ProdIt'];
if (is_array($prodit)) {
    if (isset($prodit['Article'])) { // 1-dimensional, turn into 2-dimensional
        $prodit = array($prodit);
    }
    foreach ($prodit as $obRes) {
        ...
    }
}

How do I fix these illegal string offset warnings?

The usage of the function is_array() in the beginning of your function can give you the insurance, that, if someone pass you something else than an array, the variable is reinitialised as an empty array.

Unsetting or nulling it before doing that is useless, because, as of PHP 5.3, PHP does have a garbage collector mechanism.

/**
 * @params array $array
 */
function my_function( $array ) {
   if ( ! is_array ( $array ) ) { $array = [] };
   /**
    * Or, if you don't like the short array notation:
    * if ( ! is_array ( $array ) ) { $array = array(); };
    */

   if ( ! isset( $array['where'] ) ) { $array['where'] = 'after'; }
   if ( ! isset( $array['echo'] ) ) { $array['echo'] = false; }
   if ( ! isset( $array['content'] ) ) { $array['content'] = false; }

   $array['shortcode'] = true;
   $array['devs'] = true;
   return social_warfare( $array );
}

add_shortcode( 'my_shortcode', 'my_function' );

Opencart module error: Warning: Illegal string offset 'model' in opencart/admin/model/catalog/product.php

The issue was resolved after I restructured the array. The sub-array should have a child array with language_id as a key inside of it.

The functional array should be stuctured like this:

$products_data_array[] = array(

                'product_description' => array(
                    '0' => array(
                        'name' => $name,
                        'meta_description' => $meta_description,
                        'meta_title' => $meta_title,
                        'meta_keyword' => $meta_keyword,
                        'description' => $description,
                        'tag' => $tag,
                    )
                ),
                'mciid' => $mciid,
                'model' => $model, 
                'sku' => '', 
                'upc' => '',

                'location' => '',

                'length_class_id' => '',
                'weight' => $weight,
                'weight_class_id' => '',
                'status' => '1',
                'sort_order' => '',
                'manufacturer' => $brand, 
                'manufacturer_id' => '111',

                ),
                'download' => '',
                'related' => '',
                'product_attribute' => array(
                    '0' => array(
                        'name' => '',
                        'attribute_id' => '', 
                        'product_attribute_description' => array(
                            '1' => array(
                                    'text' => "first language content"
                            )
                        )
                    )

                ),
                'option' => '',
                'points' => '',
                'product_reward' => array(
                    '1' => array(

                    )
                ),
                'product_layout' => array(
                    '0' => array(
                            'layout_id' => '2' 
                    )
                )
            );

Note: This array is functional on Version 3.0.3.8 of Opencart.
