分享一個其他網友的方法吧，小伙伴們也可以參考下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 $rate_info = file("$table.txt"); print $n_s = chop($rate_info[0]); for($start=1;$start { $value=""; for ($i=$start;$i<($start+$n_s-1);$i++) { $tmp = str_replace("&&jimmy&&"," ",chop($rate_info[$i])); $value .= "'".addslashes($tmp)."',"; } $tmp = str_replace("&&jimmy&&"," ",chop($rate_info[$start+$n_s-1])); $value .= "'".$tmp."'"; $query = "insert into $table values (".$value.")"; print mysql_error(); mysql_query($query); print $start." "; } print "ostart"; ?>以上所述就是本文的全部內容了，希望大家能夠喜歡。
