问题 I got a URL like this: http://google.de/test.php?a=b&c=d&e=f I know got to modify just one of the GET params like this: ( c is "h" instead of "d") http://google.de/test.php?a=b&c=h&e=f and redirect to the new url. All other GET params should stay the same. How am I going to do this? 回答1: I agree its best to use a library for this purpose as mentioned in other answers.

问题 Are there any rules one needs to follow when naming POST variables in a form or GET variables in a query string? Thanks- 回答1: TO answer the question literally, there really are no "rules" I'm aware of for naming $_POST and $_GET array keys in php. It's an array like any other. Take a look at this working example on Codepad: <?php $_POST['♠♣♥♦'] = 'value1'; $_POST['\'\'\'\''] = 'value2'; $_POST['<?php echo "Hello World"; ?>'] = 'value3'; $_POST[' '] = 'value4'; $_POST[''] = 'value5'; $_POST['@

问题 When I download a CSV from a Google trends query (e.g. here), I see a HTTP GET request to https://www.google.com/trends/api/widgetdata/multiline/csv with params req:{"time":"2012-02-18 2017-02-18","resolution":"WEEK","locale":"en-GB","comparisonItem":[{"geo":{},"complexKeywordsRestriction":{"keyword":[{"type":"BROAD","value":"trump"}]}}],"requestOptions":{"property":"","backend":"IZG","category":0}} token:APP6_UEAAAAAWKm9N57FxjXrnfxhxhe5SEax6DyR97sY tz:-120 The req and tz params make sense,

问题 When I send a 304 response. How will the browser interpret other headers which I send together with the 304? E.g. header("HTTP/1.1 304 Not Modified"); header("Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) . " GMT"); Will this make sure the browser will not send another conditional GET request (nor any request) until $offset time has "run out"? Also, what about other headers? Should I send headers like this together with the 304: header('Content-Type: text/html'); Do I have to send:
