Array to string conversion error in PHP

Question

I have following code to backtrace the error ....but its

$traces = debug_backtrace();

foreach ($traces as $k => $v)
{
    if ($v[\'function\'] == \'include\         


        

Answer 1

you begin with:

foreach($traces as $k=>$v) <- $traces here is an array

then you try to do

$traces.= "xxx" <- $traces here is handled as a string

i would rather define a $tracestr string for aggregating text content.
