Which of the following functions in PHP can be used to round a number?

  • round(), ceil(), floor()
  • strlen(), strpos(), substr()
  • is_numeric(), is_int(), is_float()
  • array_push(), array_pop(), array_merge()
The functions round(), ceil(), and floor() can be used to round a number in PHP. The round() function rounds a floating-point number to the nearest whole number or decimal place, the ceil() function rounds a number up to the nearest integer, and the floor() function rounds a number down to the nearest integer. These functions are commonly used for rounding calculations in PHP. It's important to note that the functions strlen(), strpos(), substr(), is_numeric(), is_int(), is_float(), array_push(), array_pop(), and array_merge() are not specifically for rounding numbers.
