Create partial ranges of an int array in PHP

Let's say I have an array like this : 

$intarray = array("300","350","399","650","625","738","983","1200","1050");

how can I display this array to user like this :

Price
_________________
[] 300  -  699  (5)
[] 700  -  999  (2)
[] 1000 -  1500 (2)

Details : as in the example I wanted to show the user not the whole elements but option to select between them by giving limits low and max limits. So if user select 300 - 699, page display the results between 300-699

That $intarray is generated dynamically so some code must handle the splitting. Array can have more elements. What I want is divide the numbers like 5 range options to show the user.

You can do a function that prints and counts the numbers in your range

public function printInRanges($startRange, $endRange)
{
$count = 0;
foreach($element in $array)
{
if($element>=$startRange && $element<=$endRange)
count++;
}
echo $startRange."-".$endRange."(".$count.")";
}

And than you can call this function with whatever ranges you want

Last Edit

if you want to do this for all your array, get your first element value (array[0]) and last element value, and call the function from a loop 

$startValue = array[0];
while($startValue + 500 < $endValue)// 500 being the value between ranges like 0-500,500-1000,1000-1500
{
printInRanges($startValue ,$startValue +500);
$startValue+=500;
}

Having in mind my comment, I assume you want to count particular ranges.

<?php
$intarray = array("300","350","399","650","625","738","983","1200","1050");
//echo "[] ". $intarray[0]. " - " .$intarray[4][0]."99"; # that was in my comment

$ranges = array(
    0   =>  array(
        'min'   =>  300,
        'max'   =>  699
    ),
    1   =>  array(
        'min'   =>  700,
        'max'   =>  999
    ),
    2   =>  array(
        'min'   =>  1000,
        'max'   =>  1500
    )
);

foreach ($intarray as $val) {
    for ($i = 0; $i < count($ranges); $i++){
        if ($val >= $ranges[$i]['min'] && $val <= $ranges[$i]['max']) {
            $range_values[$i][] = $val;
        }
    }
}

var_dump($range_values);



array (size=3)
  0 => 
    array (size=5)
      0 => string '300' (length=3)
      1 => string '350' (length=3)
      2 => string '399' (length=3)
      3 => string '650' (length=3)
      4 => string '625' (length=3)
  1 => 
    array (size=2)
      0 => string '738' (length=3)
      1 => string '983' (length=3)
  2 => 
    array (size=2)
      0 => string '1200' (length=4)
      1 => string '1050' (length=4)

You can use count() in order to display the thing in the brackets

for ($i = 0; $i < count($ranges); $i++) {
    $max = max($range_values[$i]);
    echo "[] " . min($range_values[$i]) . " - " . $max[0]."99" . " (". count($range_values[$i]).")" . "<br />";
}


[] 300 - 699 (5)
[] 738 - 999 (2)
[] 1050 - 199 (2)

Or just display the ranges (as it was the desired output?) and count($ranges_values) current iteration

for ($i = 0; $i < count($ranges); $i++) {
    echo "[] " . $ranges[$i]['min'] . " - " . $ranges[$i]['max'] . " (" . count($range_values[$i]) . ")" . "<br />";
}

[] 300 - 699 (5)
[] 700 - 999 (2)
[] 1000 - 1500 (2)

Try

$intarray = array("300","350","399","650","625","738","983","1200","1050");
sort($intarray);
$result=array();
foreach($intarray as $key=>$val){
   switch($val){
      case ($val > 300 && $val < 699):
     $result[0][] = $val;
      break;
      case ($val > 700 && $val < 999):
      $result[1][] = $val;
      break;
      case ($val > 1000 && $val < 1500):
          $result[2][] = $val;
      break;
   }
}
