}
foreach ($newarray as $month => total_booking) {
//if there is no month in array betwean to_month and from_month it
should be included in correct place as sorted
}

The best way is to take reference from the start date and end date you inputted and look it up in the master array..
Here it is(please scroll for answer)
$your_array=array
(
array
(
'month' => 'April-2014',
'total_booking' => 2
),
array
(
'month' => 'May-2014',
'total_booking' => 5
),
array
(
'month' => 'June-2014',
'total_booking' => 25
),
array
(
'month' => 'October-2013',
'total_booking' => 1
),
array
(
'month' => 'July-2014',
'total_booking' => 4
)
);
$start_date="Jan 1 2013";
$end_date="Dec 31 2014";
$timestamp1=strtotime($start_date);
$timestamp2=strtotime($end_date);
for($i=$timestamp1;$i<$timestamp2;$i=$i+24*60*60){
//echo $i;
$gapmonth[]=date('F-Y',$i);
}
$gapmonth=array_unique($gapmonth);
//convert $dataS(ORIGINAL ARRAY) to one dimentional array so the life will be easier
foreach($your_array as $val){
$derived_val[$val['month']]=$val['total_booking'];
}
foreach($gapmonth as $val){
if(array_key_exists($val,$derived_val)){
$total_booking=$derived_val[$val];
}
else{
$total_booking=0;
}
$finaldate[]=array('month'=>$val,'total_booking'=>$total_booking);
}
echo "<pre>";
print_r($finaldate);

Answer 2

Loop through it and test if values are missing:
$prev_month = false;
foreach($your_array as $k=>$values){
if($prev_month!==false){ // first itteration will be empty, dont do useless checks
// Test if themonth after the previous month matches this one
if( $prev_month+1 !== $values['month'] ){
// FILL IN THE BLANKS
// splice in at position $thisIndex (<- this you'll have to do)
array_splice( $prev_month, $thisIndex-1, 0, $newDateBookingsArray); // -1, we want it before this item!
// (dont forget to loop in case more than 1 items miss)
}
}
$prev_month = $values['month']; // save value for next round
}
Edit: TS first asked to sort the array, the code to use a custom sort can be found in the edits of this post.
