How to force conversion into a string in PHP:

PHP’s data type conversion is a forced conversion, and the conversion type is (string): converted to character String

Conversion methods: intval() floatval() strval() three types.

<?php   
$str="123.9abc";   
$int=intval($str);     //转换后数值：123   
$float=floatval($str); //转换后数值：123.9   
$str=strval($float);   //转换后字符串："123.9"

The PHP data types that allow conversion are:

• (int), (integer): converted to integer

• (float), (double), (real): Convert to floating point type

• (string): Convert to string

• ( bool), (boolean): Convert to Boolean type

• (array): Convert to array

• (object): Convert to object

There are three conversion methods for PHP data types:
