The above is a link to a readable version of my code.  The XMLHTTPREQUEST worked, and the array was pulled down.  Was able to print out the undecoded/unparsed array.  However, immediately afterwards, all code stops working.

		<script>  
			var xhr;
			 if (window.XMLHttpRequest) { // Mozilla, Safari, ...
				xhr = new XMLHttpRequest();
			} else if (window.ActiveXObject) { // IE 8 and older
				xhr = new ActiveXObject("Microsoft.XMLHTTP");
			} 
				xhr.open("POST", "PHPLibrary/selectMemberResults.php", true); 
				xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");                  
				xhr.send();
				xhr.onreadystatechange = display_data;
				var $phparray
				function display_data() {
				 if (xhr.readyState == 4) {
				  if (xhr.status == 200) {
				    //alert(xhr.responseText);	   
					$phparray = xhr.responseText;
					document.getElementById("suggestion").innerHTML = $phparray;
					//
					//
					//......................................................?
					// The above line of code is the last thing to print or 
					// to do anything that returns to the browser....
					//.......................................................?
					// All lines below do nothing............................?

					//
				  } else {
					//alert('There was a problem with the request.');
				  }
				 }
				}   
				document.write("Length of phparray Array :" + $phparray.length + "<");  
				var output = JSON.parse($phparray, function (key,val) {
					if ( typeof val === 'string' ) {
						// regular expression to remove extra white space
						if ( val.indexOf('\n') !== -1 ) {
							var re = /\s\s+/g;
							return val.replace(re, ' ');
						} else {
							return val;
						}
					}
					return val;
				} ); 
				document.write("Length of Array :" + $output.length + "<");
				for (var i=0; i < $output.length; i++)
					{
						document.getElementById("suggestion").innerHTML = $output[i].MEMBER_NAME;
					}  
		</script>
