Example #1 MysqlndUhConnection::escapeString() example

<?php
class proxy extends MysqlndUhConnection {
 public function 
escapeString($res$string) {
   
printf("%s(%s)\n"__METHOD__var_export(func_get_args(), true));
   
$ret parent::escapeString($res$string);
   
printf("%s returns %s\n"__METHOD__var_export($rettrue));
   return 
$ret;
 }
}
mysqlnd_uh_set_connection_proxy(new proxy());

proxy::escapeString(array (
  0 => NULL,
  1 => 'test0\'test',
))
proxy::escapeString returns 'test0\\\'test'
