How to Type cast variable \u00a0in PHP (Type casting)?<\/h2>\n

Typecast :\u00a0PHP <\/a>does not \u00a0support type definition of the variable. In php we never define data type<\/a> while declaring the variable<\/a>. In PHP variables automatically decide the data type on the basis of the value assignment.<\/p>\n

We can cast following data type<\/a> variable in php<\/p>\n

    \n
  1. Integer \u00a0using (int) or (integer)<\/li>\n
  2. Boolean using\u00a0(bool) or (boolean)<\/li>\n
  3. Floating Number using (float) \u00a0or (real) or (double)<\/li>\n
  4. String using (str)<\/li>\n
  5. Array using (array)<\/li>\n
  6. Object using (object)<\/li>\n
  7. Null using (unset)<\/li>\n<\/ol>\n

    For an example we are given $a=5;<\/p>\n

    we can check datatype by gettype() function \u00a0gettype($a)<\/p>\n

    now if you want to typecast \u00a0then you can do the following<\/p>\n

         \n$b= (double)$a;\n\/\/\/ for type cast to double\n\n$b= (string)$a;\n\/\/\/ for type cast to string\n\n$b= (integer)$a;\n\/\/\/for type cast to integer\n\n$b= (bool)$a;\n\/\/\/for type cast to\u00a0Boolean\n\n$b= (array)$a;\n\/\/\/for type cast to array\n\n\/\/\/ Another type to typecast is settype()<\/strong>\n\n$a=242;\n\nsettype($a,\\'string\\');\n<\/code><\/pre>\n
    Note: Settype changes datatype of variable ,where as typecasting \u00a0of changes datatype of new variable to which value is assign .<\/p>\n","protected":false},"excerpt":{"rendered":"
