How to convert numbers into strings in php

php method to convert numbers into strings: You can use the strval() function to convert numbers into strings, such as [$str="123.9abc";strval($float);]. It can also be achieved through forced type conversion or the universal type conversion function settype().

There are three conversion methods for PHP data types:

1. Forced conversion, enclosed in parentheses before the variable to be converted The target type

2. Use three specific type conversion functions, intval(), floatval(), strval()

3. Use the general type conversion function settype(mixed var,string type)

var_dump($num2); //输出int(3)   
?>

th Two conversion methods:

<?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 third conversion method:

<?php   
$num4=12.8;   
$flg=settype($num4,"int");   
var_dump($flg);  //输出bool(true)   
var_dump($num4); //输出int(12)
