PHP Data type conversions
PHP's data type conversions are cast, and the PHP data types that are allowed to be converted are:
• (int), (integer): Convert to Reshape
• (float), (double), (real): Convert to floating-point
• (string): Convert to String
• (bool), (Boolean): Convert to Boolean type
• (array): Convert an array
• (object): Convert to Object
There are three ways to convert PHP data types:
before the variable to be converted, add the target type in parentheses
Use 3 specific types of conversion functions, intval (), Floatval (), Strval () ,
using a common type conversion function Settype ( Mixed var,string type)
the first way to convert: (int) (bool) ( float) (string) (array) (object)
 
1.<?php
3. $num 2= (int) $num 1;
4.var_dump ($num 1);// Output float (3.14)
5.var_dump ($num 2);//output int (3)
6.? >
&NBSP;
1.<?php
3. $int =intval ($STR); //converted value: 123
4. $float =floatval ($STR); Converted value: 123.9
5. $str =strval ($float); //converted string: "123.9" &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;
6.? >
The third mode of conversion: settype ();
1.<?php
2. $num 4=12.8;
3. $flg =settype ($num 4, "int");
4.var_dump ($FLG); output bool (TRUE)
5.var_dump ($num 4); Output int (12)
6.?>
