Description:

<?php
class test { public $value = 'Hi'; }                                                                                          
$obj = new test();                                                                                                            
trim($obj);
?>
result: Warning: trim() expects parameter 1 to be string, object given

<?php
$content = file_get_contents('http://php.net');                                                                               
while ($i = 1) { trim(tidy_parse_string($content, $tidy_config, 'utf8')); }
?>
result: Fatal error: Allowed memory size of 1048576 bytes exhausted (tried to 
allocate 104 bytes)
php: tidylib.c:168: tidyDocRelease: Assertion `doc->docIn == ((void *)0)' 
failed.

I think need warning and not eat all memory
thx

You have your memory limit set really low and you are looping infinitely over a 
tidy_parse_string call against a 50k blob of html.
This has nothing to do with trim.  You are running out of memory doing all the 
tidy stuff long before trim() is even called.

At first time it was: Fatal error: Allowed memory size of 1073741824 bytes 
exhausted (tried to allocate 3 bytes)

btw:
In http://php.net/manual/en/tidy.examples.basic.php we get:
<?php
$tidy = new tidy;
$tidy->parseString($html, $config, 'utf8');
$tidy->cleanRepair();
echo $tidy;
?>
If before echo() we put:
var_dump(is_object($tidy));
var_dump(is_string($tidy));

result will be:
bool(true)
bool(false)

In php.net/manual/en/function.echo.php says echo wanna string, not object
And if use $tidy->value problem resolve.

What I don't understand?
thx
