php多条json转换为数组解决思路

php 多条json 转换为数组
{"SchemeName":"湖田窑遗址（葫芦窑、马蹄窑）本体保护工程设计方案","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"江西省"},{"SchemeName":"元中都遗址宫城南门、西南角台夯土保护工程","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"河北省"},{"SchemeName":"元中都遗址环境整治工程","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"河北省"},{"SchemeName":"内丘邢窑遗址保护大棚","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"河北省"}



怎么转换为数组
------解决方案--------------------
加对中括号
注意编码要是 utf-8的

$s =<<< TXT
[{"SchemeName":"湖田窑遗址（葫芦窑、马蹄窑）本体保护工程设计方案","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"江西省"},{"SchemeName":"元中都遗址宫城南门、西南角台夯土保护工程","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"河北省"},{"SchemeName":"元中都遗址环境整治工程","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"河北省"},{"SchemeName":"内丘邢窑遗址保护大棚","SchemeType":"技术方案(委托第三方)","DeclareYear":"2014","SchemeStatus":"评审中","Province":"河北省"}]
TXT;

print_r(json_decode($s, 1));

Array
