Great function, but you have a few bugs.
At the line:
foreach($arr['args'] as $v)
Change it to:
$args = array();
if(!empty($arr['args'])) foreach($arr['args'] as $v)
And since line & file are not present in the array if calling from the error handler,
$Line = (isset($arr['line'])? $arr['line'] : "unknown");
$File = (isset($arr['file'])? $arr['file'] : "unknown");
and substitute accordingly.
Here's my version of it, alas with different formatting:
----------------------------------------
function DBG_GetBacktrace()
{
$s = '';
$MAXSTRLEN = 64;
$s = '<pre align=left>';
$traceArr = debug_backtrace();
array_shift($traceArr);
$tabs = sizeof($traceArr)-1;
foreach($traceArr as $arr)
{
for ($i=0; $i < $tabs; $i++) $s .= ' ';
$tabs -= 1;
$s .= '<font face="Courier New,Courier">';
if (isset($arr['class'])) $s .= $arr['class'].'.';
$args = array();
if(!empty($arr['args'])) foreach($arr['args'] as $v)
{
if (is_null($v)) $args[] = 'null';
else if (is_array($v)) $args[] = 'Array['.sizeof($v).']';
else if (is_object($v)) $args[] = 'Object:'.get_class($v);
else if (is_bool($v)) $args[] = $v ? 'true' : 'false';
else
{
$v = (string) @$v;
$str = htmlspecialchars(substr($v,0,$MAXSTRLEN));
if (strlen($v) > $MAXSTRLEN) $str .= '...';
$args[] = "\"".$str."\"";
}
}
$s .= $arr['function'].'('.implode(',
',$args).')</font>';
$Line = (isset($arr['line'])? $arr['line'] : "unknown");
$File = (isset($arr['file'])? $arr['file'] : "unknown");
$s .= sprintf("<font color=#808080 size=-1> # line %4d, file: <a
href=\"file:/%s\">%s</a></font>",
$Line, $File, $File);
$s .= "\n";
}
$s .= '</pre>';
return $s;
}
