Php forced type conversion

Php forced type conversion

Forced type conversion in php usually occurs in the environment where arithmetic operators are involved. arithmetic operators are common numeric operators. The operated content is generally called an operation object or operand. Arithmetic operators are usually used for integer or double-precision (also known as floating point or real number) data. If the object involved in arithmetic operations contains strings, php will try to convert these strings into a number. If it contains the character "e" or "E", it will be treated as a scientific notation and converted to a floating point number. Otherwise, it will be converted to an integer. Php searches for numbers at the beginning of the string and uses these numbers as the value of the string. If no number is found, the value of the string is 0.
