tags

问题 I am working with Android and ISO14443 type B tags and there is an issue that I am not able to solve. Hopefully someone can give a hint. When NFC setting of the phone are turned on, it starts sending REQA and REQB commands in order to discover if any tag is present. The issue is that by default this is done with a periodicity of 2 seconds and I would like to modify that time to make it shorter. I see that most apps maintain this scan period, but there are some apps such as TagInfo from NXP

问题 My problem is how to replace the src value of a <script> tag inside a string like in this example (well, I need this in a more general scenario of properties inside tags): $data = <<<EOD <script language="javascript" src= "../tests/ajax-navigation.js"></script> ... <img src="../404.jpg" alt="404"> ...
