How to Use the PHP Is_Numeric() Function

How to Use the PHP Is_Numeric() Function The is_numeric() function in the  PHP programming language is used to evaluate whether a value is a number or numeric string. Numeric strings contain any number of digits, optional signs such as or -, an optional decimal, and an optional exponential. Therefore, 234.5e6 is a valid numeric string. Binary notation and hexadecimal notation are not allowed.   The  is_numeric()  function can be used within an if() statement to treat numbers in one way and non-numbers in another. It returns true or false. Examples of the Is_Numeric() Function For example: ?php if (is_numeric(887)) { echo Yes; } else { echo No; } ? Because 887 is a number, this echos Yes. However: ?php if (is_numeric(cake)) { echo Yes; } else { echo No; } ? Because cake is not a number, this echos No. Similar Functions A similar function, ctype-digit(), also checks for numeric characters, but only for digits- no optional signs, decimals, or exponents allowed. Every character in the string text must be a decimal digit for the return to be true. Otherwise, the function  returns false. Other similar functions include: is_null() – Finds whether a variable is NULLis_float() – Finds whether the type of a variable is floatis_int() – Find whether the type of a variable is integeris_string() – Find whether the type of a variable is stringis_object() – Finds whether a variable is an objectis_array() – Finds whether a variable is an arrayis_bool()  Ã¢â‚¬â€œ Finds out whether a variable is a boolean About PHP PHP is an abbreviation for Hypertext Preprocessor.
