There are a lot of great answers here - but I found my issue was quite a bit more simple.

I was trying to run the following command:

<pre><code>$x['name'] = $j['name'];
</code></pre>

and I was getting this <code>illegal string</code> error on <code>$x['name']</code> because I hadn't defined the array first. So I put the following line of code in before trying to assign things to <code>$x[]</code>:

<pre><code>$x = array();
</code></pre>

and it worked.

blocks|key|613294|text|这个问题有点晚了，但对于其他正在搜索的人来说:我通过使用错误的值(Type)初始化得到了这个错误：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|613295|$varName+=+'';

A little bit late to the question, but for others who are searching: I got this error by initializing with a wrong value (type):

<pre><code>$varName = '';
$varName["x"] = "test"; // causes: Illegal string offset
</code></pre>

The right way is:

<pre><code> $varName = array();
 $varName["x"] = "test"; // works

blocks|key|397066|text|从PHP5.4开始，我们需要传递函数期望的相同数据类型值。例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|397067|function+testimonial($id);+//+This+function+expects+$id+as+an+integer|code-block|syntax|javascript|397068|调用此函数时，如果提供的字符串值如下所示：|397069|$id+=+$array['id'];+//+$id+is+of+string+type

As from PHP 5.4 we need to pass the same datatype value that a function expects. For example:

<pre><code>function testimonial($id); // This function expects $id as an integer
</code></pre>

When invoking this function, if a string value is provided like this:

<pre><code>$id = $array['id']; // $id is of string type
testimonial($id); // illegal offset warning
</code></pre>

This will generate an illegal offset warning because of datatype mismatch. In order to solve this, you can use <a href="http://php.net/manual/en/function.settype.php" rel="noreferrer"><code>settype</code></a>:

<pre><code>$id = settype($array['id'],"integer"); // $id now contains an integer instead of a string
testimonial($id); // now running smoothly
</code></pre>

this is because you never define what is $memcachedConfig, so by default are treated by string not arrays..

It's an old one but in case someone can benefit from this. 
You will also get this error if your array is empty. 

In my case I had:

$buyers_array = tep_get_buyers_info($this_buyer_id); // returns an array
...
echo $buyers_array['firstname'] . ' ' . $buyers_array['lastname'];

<pre><code>$buyers_array = array();
$buyers_array = tep_get_buyers_info($this_buyer_id); // returns an array
...
if(is_array($buyers_array)) {
