MySQL函数库：mysql_field_type

mysql_field_type

(PHP3 , PHP4)

mysql_field_type ---&">nbsp; 取得指定栏位的型态

语法 : string mysql_field_type (int result, int field_offset)

说明 :

mysql_field_type( )类似于mysql_field_name( )，参数也一样，但是此函数所传回的是型态，这将会是"int"，"real"，"string"，"blob"之一，或是其它，细节请参考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。
