27 gru 2011 · PHP does not support unsigned integers. Integer size can be determined using the constant PHP_INT_SIZE, and maximum value using the constant PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5. If PHP encounters a number beyond the bounds of the integer type, it will be interpreted as a float instead.
16 gru 2011 · If you want the numerical value of a string and you don't want to convert it to float/int because you're not sure, this trick will convert it to the proper type: function get_numeric($val) { if (is_numeric($val)) { return $val + 0; } return 0; } Example: <?php get_numeric('3'); // int(3) get_numeric('1.2'); // float(1.2) get_numeric('3.0 ...
Example #1 number_format () Example. For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ') as thousand separator. The following example demonstrates various ways to format a number: <?php. $number = 1234.56; // english notation (default) $english_format_number = number_format($number);

A helper class to convert integer to binary strings and vice versa. Useful for writing and reading integers to / from files or sockets. <?php class int_helper {public static function int8 ($i) {return is_int ($i) ? pack ("c", $i) : unpack ("c", $i)[1];} public static function uInt8 ($i) {return is_int ($i) ? pack ("C", $i) : unpack ("C", $i)[1];}
intval (mixed $value, int $base = 10): int. Returns the int value of value, using the specified base for the conversion (the default is base 10). intval () should not be used on objects, as doing so will emit an E_WARNING level error and return 1.
The library function intval allows values to be converted to int. Converting to Floating-Point Type. The result type is float. If the source type is int, if the precision can be preserved the result value is the closest approximation to the source value; otherwise, the result is undefined.
