I might have misunderstood the requirement but can't you do a str_replace on the char you want to replace? If you need to remove multiple chars then preg_replace<br />

<pre><code id="code-20-42380650-1">&lt;?php
$source = &quot;D♯A♭B𝄪C♯EF𝄫G&quot;;
$result = preg_replace('[♭|♯|𝄪|𝄫]', '', $source);
echo $result;</code></pre>
</div>

$str = preg_replace(&quot;/[^A-Za-z0-9<wbr />?! ]/&quot;,&quot;&quot;,$str);<br />
this will allow only letters numbers and spaces in your string

$str = preg_replace("/[^A-Za-z0-9?! ]/","",$str);

It's cool man I was in C# before I was suspended when marijuana was found in my dorm. I knew what you were saying I was smoking more marijuana instead of coding.

I'm writing my first object oriented script that spells triads and chords derived from the major, harmonic minor or jazz minor.<br />
<br />
I need to remove the characters &nbsp;♭ ♯ 𝄪 &nbsp;𝄫 from a note.<br />

So I need to remove the ♯ from D♯ and return a D.<br />

What is the best way to do this?
