读取文本文件并将内容传输到mysql数据库

Question

I need a php script to read a .txt file.

The content of the text file are like this:

data.txt

145|Joe Blogs|17/03/1954
986|Jim Smith|12/01/1976
234|Paul Jones|19/07/1923
098|James Smith|12/09/1998
234|Carl Jones|01/01/1925

These would then get stored into a database like this

**DataID |Name |DOB **

234    |Carl Jones|01/01/1925

I would be so grateful if someone could give me script to achieve this.

Update:

<?
$handle = @fopen("data.txt", "r");
$conn = mysql_connect("localhost","username","password"); 
mysql_select_db("mydatabase",$conn);
while (!feof($handle)) // Loop til end of file.
{
$buffer = fgets($handle, 4096);
 // Read a line.
list($a,$b,$c)=explode("|",$buffer);
//Separate string by the means of |
echo $a."-".$b."-".$c."<br>";
$sql = "INSERT INTO data_table (iddata, name, age) VALUES('".$a."','".$b."',".$c.")";   
mysql_query($sql,$conn) or die(mysql_error());
}
?>

get the following error error in your SQL syntax; ...for the right syntax to use near ')' at line 1

Answer 1

What you may be looking for is MySQL's built-in function LOAD DATA INFILE to load a text file containing values for a database into a database.

The LOAD DATA INFILE statement reads rows from a text file into a table at a very high speed. The file name must be given as a literal string.

Example:

LOAD DATA INFILE 'data.txt' INTO TABLE my_table;

You could also specify the delimiters inside of your text-file, like so:

LOAD DATA INFILE 'data.txt' INTO TABLE my_table FIELDS TERMINATED BY '|';

Update:

Here is a full-working example, I uploaded a test data file here and here is my PHP code.

$string = file_get_contents("http://www.angelfire.com/ri2/DMX/data.txt", "r");
$myFile = "C:/path/to/myFile.txt";
$fh = fopen($myFile, 'w') or die("Could not open: " . mysql_error());
fwrite($fh, $string);
fclose($fh);

$sql = mysql_connect("localhost", "root", "password");
if (!$sql) {
    die("Could not connect: " . mysql_error());
}
mysql_select_db("my_database");
$result = mysql_query("LOAD DATA INFILE '$myFile'" .
                      " INTO TABLE test FIELDS TERMINATED BY '|'");
if (!$result) {
    die("Could not load. " . mysql_error());
}

Here what the table looked before running my PHP code:

mysql> select * from test;
+--------+-----------+------------+
| DataID | Name      | DOB        |
+--------+-----------+------------+
|    145 | Joe Blogs | 17/03/1954 |
+--------+-----------+------------+
1 row in set (0.00 sec)

And here is the result after:

mysql> select * from test;
+--------+-------------+------------+
| DataID | Name        | DOB        |
+--------+-------------+------------+
|    145 | Joe Blogs   | 17/03/1954 |
|    234 | Carl Jones  | 01/01/1925 |
|     98 | James Smith | 12/09/1998 |
|    234 | Paul Jones  | 19/07/1923 |
|    986 | Jim Smith   | 12/01/1976 |
+--------+-------------+------------+
5 rows in set (0.00 sec)

Answer 2

open txt file using fopen:

$handle = @fopen("xyz.txt", "r"); //read line one by one
$values='';

while (!feof($handle)) // Loop til end of file.
{
    $buffer = fgets($handle, 4096); // Read a line.
    list($a,$b,$c)=explode("|",$buffer);//Separate string by the means of |
    //values.=($a,$b,$c);// save values and use insert query at last or

    // use mysql insert query here
}

THATS IT

Answer 3

$sql = "INSERT INTO data_table (iddata, name, age) VALUES('".$a."','".$b."', **'** ".$c." **'** )";

issue is with the single quotes around $c. There is no single quotes. Add it.

Answer 4

@ Anthony Forloney Your answer is right,just add the vertical bar[ | ] at each very last of each row like this on your data.txt file...

and rest is same as in your answer.This is working for me...

dont forget to add the quotes for varchar type for inserting datas to table....
