如何从PHP中的字符串中单独删除特殊字符？

preg_replace(\"/[^A-Za-z0-9\\s]/\", \"\", $str);

$str = \"Hindustan Times, Oct 2009, Review by a well known Art critic on her solo exhibition at Jaipur, Jawahar Kala Kendra\'th, 23-29th Sep 2009. \\\"Many of her paintings including her self portrait, stress in humanities singular plight and aimlessness\";
$search     = array(\',\', \'\"\', \"\'\", \'-\', \'.\');
$clean      = str_replace($search, \' \', $str); 
echo $clean;
