Running multiple PHP scripts at once from command line initiated by cron jobs
<p>I have a question concerning cron jobs. </p>

<p>Here is a brief look at the situation:</p>

<ol>
<li><p>I call a php script every minute (*****) (PHP CLI).</p></li>
<li><p>The PHP script makes a database request to check if there are any emails to send for that specific minute and sends them accordingly.</p></li>
<li><p>The PHP script needs more than 1 minute for execution (huge database -> lots of emails to send -> takes time even though using multiple threads)</p></li>
<li><p>The same PHP script gets called the next minute (*****), while its first execution hasn't finished its execution yet.</p></li>
</ol>

<p>Will the first execution interrupt, when the script is called again (every minute it is called), even though the first execution hasn't finished yet?</p>

<p>I hope the situation is clear for you.</p>

<p>Operating System: obviously Linux ...</p>

<p>Thanks for your help!</p>
