PHP Array To String Notice
I get the following notice on my webpage.
A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
Filename: libraries/Template.php
Line Number: 3859
The line number 3859 is this:
The following is the entire Method. It is part of the Expression Engine CMS. Maybe it can be defined in here someplace?

That error typically occurs when you try to access an array as a string. Even when all the array elements are strings, you have to pass them individually in the format $array[0] or $array['name']. (Substitute the name of your array in place of 'array') You can't pass the whole array.
I'm not sure I understand that as it applies to what I have posted. Can you elaborate just a little more?
If any of the variable values in line 3859 above is an array instead of a simple string, the function call will fail with the error you mentioned at the top.
Hi rgranlund. Let me say I never used and I don't know expression-engine. That said, looking at your function I see there are 2 main conditions:
and
Depending of the value of this conditions the value of the variable $value is set. Now, is it possible that the second condition is only partially true? That is: could be $value an array but its count be 1 or 3 or other or be its first value not an array? Because if $value is an array the first condition is false but if it is an array but its count is let's say 4 or its first element is not an array the second condition too ius false and so at the end of the function when you have:
$value is still an array and this raises the Notice. I think this is the problem and you have to investigate about this. Maybe you can elaborate the condition and set $value as string even if the other two conditions are false
if (is_string($value)) {
and
if (is_array($value) && count($value) == 2 && is_array($value[1])) {

if (is_array($value){

...
}
else
{
... make somehow $value be a string
}
}
