how to combine two unsigned 32bit integers to 64bit integer in php?
<p>I have two unsigned 32 bit integers that I need to combine to make one long integer or a string it does not matter if it is in string format as long as I have the number. for example:</p>

<p>low: -589298671</p>

<p>high: 4</p>

<p>thanks!</p>
