CSV script

[max101]

Hi all,

 

How would one write a csv script that uses the 1st row to match up database names and following rows for the raw data,

as well as update data that is already present. I have been trying to do this for 2 days and I keep hitting dead ends.

If anyone can point me in the right direction it would be great.

I would do it the same way any CVS is built:

 

lname,fname,address,city,st,zip

Atomic,Team,XXXXXX Ouzel Falls Rd,Big Sky,MT,59716

 

Then take the file into file() so I have an array. Shift the first line off and explode it and build an insert line. Then loop through the rest of the file array using the value to explode then fill the insert line and do it.

I found this script works perfectly, but I need to adapt it so if unique id fields exist in the database and the csv are the same, it updates it on the db, but if its a new entry it does an insert.

Here is the script I have found .

 

<?php

/* Code at http://legend.ws/blog/tips-tricks/csv-php-mysql-import/
/* Edit the entries below to reflect the appropriate values
/********************************/
$databasehost = "localhost";
$databasename = "csv_test";
$databasetable = "user";
$databaseusername ="root";
$databasepassword = "";
$fieldseparator = ",";
$lineseparator = "\n";
$csvfile = "user.csv";
/********************************/
/* Would you like to add an ampty field at the beginning of these records?
/* This is useful if you have a table with the first field being an auto_increment integer
/* and the csv file does not have such as empty field before the records.
/* Set 1 for yes and 0 for no. ATTENTION: don't set to 1 if you are not sure.
/* This can dump data in the wrong fields if this extra field does not exist in the table
/********************************/
$addauto = 0;
/********************************/
/* Would you like to save the mysql queries in a file? If yes set $save to 1.
/* Permission on the file should be set to 777. Either upload a sample file through ftp and
/* change the permissions, or execute at the prompt: touch output.sql && chmod 777 output.sql
/********************************/
$save = 0;
$outputfile = "output.sql";
/********************************/


if(!file_exists($csvfile)) {
echo "File not found. Make sure you specified the correct path.\n";
exit;
}

$file = fopen($csvfile,"r");

if(!$file) {
echo "Error opening data file.\n";
exit;
}

$size = filesize($csvfile);

if(!$size) {
echo "File is empty.\n";
exit;
}

$csvcontent = fread($file,$size);

fclose($file);

$con = @mysql_connect($databasehost,$databaseusername,$databasepassword) or die(mysql_error());
@mysql_select_db($databasename) or die(mysql_error());

$lines = 0;
$queries = "";
$linearray = array();

foreach(split($lineseparator,$csvcontent) as $line) {

$lines++;

$line = trim($line," \t");

$line = str_replace("\r","",$line);

/*get COLUMN NAMEs from first line of CSV */
if($lines==1) {
$columns=explode($fieldseparator,$line);
$columnsql=implode(",",$columns);
echo $columnsql;
continue;
} 

/************************************

************************************/
$line = str_replace("'","\'",$line);
/*************************************/

$linearray = explode($fieldseparator,$line);

$linemysql = implode("','",$linearray);

if($addauto)
	$query = "insert into $databasetable values('','$linemysql');";
else
	$query = "insert into $databasetable values('$linemysql');";

$queries .= $query . "\n";

@mysql_query($query);
}

@mysql_close($con);

if($save) {

if(!is_writable($outputfile)) {
	echo "File is not writable, check permissions.\n";
}

else {
	$file2 = fopen($outputfile,"w");

	if(!$file2) {
		echo "Error writing to the output file.\n";
	}
	else {
		fwrite($file2,$queries);
		fclose($file2);
	}
}

}

echo "Found a total of $lines records in this csv file.\n";
