PHP remove all spaces after specific character
<p>I have a text file that looks something like this:</p>

<pre><code>What word is on page 9, 4 words from the left on line 15?   account
What word is on page 11, 2 words from the left on line 5?   always
</code></pre>

<p>Is there a way that I can remove all of the spaces after the "?" so it looks something like this (the space amounts are all different throughout the actual text file):</p>

<pre><code>What word is on page 9, 4 words from the left on line 15?account
What word is on page 11, 2 words from the left on line 5?always
</code></pre>
