ठीक है, सभी चरों को हटाने के लिए, शायद सबसे सुंदर है
$url = strtok($url, '?');
strtok
यहाँ के बारे में देखें ।
इसका सबसे तेज़ (नीचे देखें), और बिना '' अच्छी तरह।
एक url + querystring लेने के लिए और सिर्फ एक वैरिएबल को हटाने के लिए (बिना रेगेक्स रिप्लेसमेंट का उपयोग किए, जो कुछ मामलों में तेज हो सकता है), आप कुछ ऐसा कर सकते हैं:
function removeqsvar($url, $varname) {
list($urlpart, $qspart) = array_pad(explode('?', $url), 2, '');
parse_str($qspart, $qsvars);
unset($qsvars[$varname]);
$newqs = http_build_query($qsvars);
return $urlpart . '?' . $newqs;
}
एक एकल संस्करण को हटाने के लिए एक रेगीक्स लग सकता है जैसे:
function removeqsvar($url, $varname) {
return preg_replace('/([?&])'.$varname.'=[^&]+(&|$)/','$1',$url);
}
कुछ अलग-अलग तरीकों की समयावधि का उपयोग करता है, यह सुनिश्चित करता है कि समय-सीमा रीसेट करें
