Convert Numeric Strings In Multi-dimensional Array To Int

I have a multi-dimensional array: array(3) { [0]=> array(2) { [0]=> string(3) 'ABC' [1]=> string(3) '744' } [1]=> array(2) { [0]=>

Solution 1:

You can use intval, like the other answers suggested, in conjunction with array_walk_recursive:

array_walk_recursive($array, function(&$item) {
    if (is_numeric($item)) {
        $item = intval($item);
    }
});

Solution 2:

You can implement a recursive function as follows, which will take an array of any size and dimension.

functionconvertArray(myArray){
    convertedArray=array();
    foreach(myArray as key=>value){
        if(is_array(value)){
            convertedArray[key] = convertArray(value);      
        }else{
            temp = intval(value);
            if(temp==0){
                convertedArray[key] = value;
            }else{
                convertedArray[key] = temp;
            }       
        }
    }
    return convertedArray;
 }

Solution 3:

Later I have to use this array in json_encode() function and in my javascript process numeric values must be integer-type.

Have you checked the JSON Predefined Constants:

$result = json_encode($array, JSON_NUMERIC_CHECK);

JSON_NUMERIC_CHECK (int)

Encodes numeric strings as numbers. Available as of PHP 5.3.3.

Solution 4:

$variable = array(3) { 
        [0]=> array(2) { 
                        [0]=> string(3) "ABC" 
                        [1]=> string(3) "744" } 
        [1]=> array(2) { 
                         [0]=> string(3) "DEF" 
                         [1]=> string(2) "86" } 
        [2]=> array(2) { 
                         [0]=> string(3) "GHI" 
                         [1]=> string(1) "2"  }
    } 

foreach($variableas$key=>$arrayStrings)
    foreach($arrayStringsas$innerKey=>$string)
           if(is_numeric($string))
              $variable[$key][$innerKey] = intval($string);

Solution 5:

just use intval(string);

ref: http://php.net/manual/en/function.intval.php

EDIT:

If you will convert the whole array it wont work. Then you have to test the non-int values so it wont be converted.

inval($value) will return 0 for non-int value then you have to test if the value was 0 or just non-int value.

If you always have the int value as a second index in array then just use intval($value);

foreach ($aas &$ar) {
  $ar[1] = intval($ar[1]);
}
