mysql_field_type
(PHP3 , PHP4)
mysql_field_type --- 取得指定欄位的型態
語法 :
string mysql_field_type(int result, int field_offset)說明 :
mysql_field_type( )類似於mysql_field_name( )，參數也一樣，但是此函式所傳回的是型態，這將會是"int"，"real"，"string"，"blob"之一，或是其它，細節請參考MySQL文件。
Example :
<?php
mysql_connect ("localhost:3306");
mysql_select_db ("wisconsin");
$result = mysql_query ("SELECT * FROM onek");
$fields = mysql_num_fields ($result);
$rows = mysql_num_rows ($result);
$i = 0;
$table = mysql_field_table ($result, $i);
echo "Your '".$table."' table has ".$fields." fields and ".$rows." records <BR>";
echo "The table has the following fields <BR>";
while ($i < $fields) {
$type = mysql_field_type ($result, $i);
$name = mysql_field_name ($result, $i);
$len = mysql_field_len ($result, $i);
$flags = mysql_field_flags ($result, $i);
echo $type." ".$name." ".$len." ".$flags."<BR>";
$i++;
}
mysql_close();
?>
相容的mysql_fieldtype( )也可以使用。
