You can use <code>strtok</code> to get string before first occurence of <code>?</code>

<pre><code>$url = strtok($_SERVER["REQUEST_URI"], '?');
</code></pre>

<code>strtok()</code> represents the most concise technique to directly extract the substring before the <code>?</code> in the querystring. <code>explode()</code> is less direct because it must produce a potentially two-element array by which the first element must be accessed.

Some other techniques may break when the querystring is missing or potentially mutate other/unintended substrings in the url -- these techniques should be avoided.

A <a href="https://3v4l.org/fRNSk" rel="noreferrer">demonstration</a>:

<pre><code>$urls = [
 'www.example.com/myurl.html?unwantedthngs#hastag',
 'www.example.com/myurl.html'
];

foreach ($urls as $url) {
 var_export(['strtok: ', strtok($url, '?')]);
 echo "\n";
 var_export(['strstr/true: ', strstr($url, '?', true)]); // not reliable
 echo "\n";
 var_export(['explode/2: ', explode('?', $url, 2)[0]]); // limit allows func to stop searching after first encounter
 echo "\n";
 var_export(['substr/strrpos: ', substr($url, 0, strrpos( $url, "?"))]); // not reliable; still not with strpos()
 echo "\n---\n";
}
</code></pre>

Output:

<pre><code>array (
 0 =&gt; 'strtok: ',
 1 =&gt; 'www.example.com/myurl.html',
)

 0 =&gt; 'strstr/true: ',
