Homephp教程PHP源码数组值拼接成字符串

数组值拼接成字符串            

将所有数组值拼接成一个字符串 
php自带的 implode 将数组拼接成一个字符串,这个方法有一个不足就是,数组的值不能是数组 只能是字符或者数字之类的基本类型 ,如果数组中的值也是一个数组的话,那么将会转换失败 。我在实际项目中遇到过这的需求,今天把我写好的代码分享给大家。希望,对需要的朋友有所帮助。 
不足之处,敬请包涵。

<?php
class Convert 
{
    public static  function arrayConvertString( $array ,$join )
    {
        $result = "" ;
         
        foreach ( $array  as $k => $v )
        {
            if( is_array( $v ) )
            {
                $result .= $join. self::arrayConvertString( $v , $join ) ;
            }
            else
            {
                $result .= $join . $v ;
            }
            $result = preg_replace( "~^" . $join . "~" , "", $result ) ;
        }
         
        return $result ;
    }
}
// test
$array = array( array(1,2,3,4,5),array("x1","x2","x3","x4","x5") ) ;
$str = Convert::arrayConvertString( $array , ",") ;
echo $str ;
// echo:1,2,3,4,5,x1,x2,x3,x4,x5
?>
