title: How do I create a timestamp from a separate date string and time string in PHP?
body: <p>I need some assistance. </p>
  
  <p>The code uses a <code>date()</code> function to acquire the <em>report date</em>, while the <em>availability times</em> are manually entered by users. The <em>availability times</em> are then compared to a <em>static time</em> in order to show whether the process was complete on time. </p>
  
  <p>This process works perfectly if all processes run on the same day; however inaccurate reporting occurs when the process completes before midnight of the previous day. This is where I need some assistance.</p>
  
  <p>I need to take the time string, which is set as <code>H:i</code> format, and merge it with the date string, which is set as <code>yyyy/mm/dd</code>. Once this is performed, I can compare it to the <em>report date stamp</em> to get proper reporting.</p>
