You are writing a PHP script and you need to check if a variable contains a numeric value. How would you do this?

  • is_numeric($variable)
  • is_string($variable)
  • is_integer($variable)
  • is_bool($variable)
To check if a variable contains a numeric value in PHP, you can use the is_numeric() function. The is_numeric() function checks if a variable can be evaluated as a number, whether it is an integer, float, or a numeric string. It returns true if the variable is numeric and false otherwise. This function is useful when you need to validate the numeric nature of a variable. Learn more: https://www.php.net/manual/en/function.is-numeric.php
