Apologies if this has been posted before - I've searched through the forum and googled, but as I don't exactly know what I'm looking for, the results haven't been great. As you'll gather, I'm totally new to PHP, so please bear with me...
I'm trying to import a .csv into MySQL using the PHP script below. The script is working fine except for the fact that some columns are spilling over into the next column during the import. This must be to do with the way that the csv is formatted (separated by ',' "enclosed by '"'). Just wondering if anyone could tell me what I need to edit in the script below to take account of this:
Code: Select all
<?
/********************************************************************************************/
/* Code at http://legend.ws/blog/tips-tricks/csv-php-mysql-import/
/* Edit the entries below to reflect the appropriate values
/********************************************************************************************/
$databasehost = "";
$databasename = "";
$databasetable = "";
$databaseusername ="";
$databasepassword = "";
$fieldseparator = ",";
$lineseparator = "\n";
$csvfile = "upload/export.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 = 1;
$outputfile = "output.sql";
/********************************************************************************************/
if(!file_exists($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);
/************************************************************************************************************
This line escapes the special character. remove it if entries are already escaped in the csv file
************************************************************************************************************/
$line = str_replace("'","\'",$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";
?>
If it's of any use, the following command works fine if I run it from the db console. The fact that this works suggests to me that there is something missing in the script that deals with the formatting?
Code: Select all
load data local infile '/upload/export.csv' into table Test fields terminated by ',' enclosed by '"' lines terminated by '\n' ignore 1 lines (Field1, Field2, Field2, etc);
