PHP工作筆記：數組轉字符串與字符串轉數組

一個數組要入庫，發現不可以，特定用函數轉為字符串入庫

$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，並轉為字符串

$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);

轉換后的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來使用：

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