php 字符串 -- 数组

　　1. 数组-->字符串

$payment= array(2) { => string(2) "10" => string(2) "20" }
$res['payment'] = implode('+',$payment);
//$res['payment']= string(5) "10+20"
　　2. 字符串 ->数组

paymentAllStr[]=str_split($res['payment'])
　　array(5) { => string(1) "1" => string(1) "0" => string(1) "+" => string(1) "2" => string(1) "0" } /

$payment = explode('+',$res['payment'])
　　array(2) { => string(2) "10" => string(2) "20" }
