PHP工作笔记：数组转字符串与字符串转数组

一个数组要入库，发现不可以，特定用函数转为字符串入库

$data = array(
    'http://img4.bitautoimg.com/autoalbum/files/20110420/734/22494073435215_1565563_15.jpg',
    'http://img4.bitautoimg.com/autoalbum/files/20110420/718/22494071876770_1565547_15.jpg',
    'http://img2.bitautoimg.com/autoalbum/files/20110420/671/22494067187672_1565545_15.jpg'
);

用“,”分割，并转为字符串

$data = array(
    'http://img4.bitautoimg.com/autoalbum/files/20110420/734/22494073435215_1565563_15.jpg',
    'http://img4.bitautoimg.com/autoalbum/files/20110420/718/22494071876770_1565547_15.jpg',
    'http://img2.bitautoimg.com/autoalbum/files/20110420/671/22494067187672_1565545_15.jpg'
);
$data = implode(",",$data);

转换后的data效果：

http://img4.bitautoimg.com/autoalbum/files/20110420/734/22494073435215_1565563_15.jpg,http://img4.bitautoimg.com/autoalbum/files/20110420/718/22494071876770_1565547_15.jpg,http://img2.bitautoimg.com/autoalbum/files/20110420/671/22494067187672_1565545_15.jpg

　　把字符串按照分隔符切割出来使用：

$newdata = explode(",",$data);
