Oh, thank you so much for writing!
Well, I have now collected some code (with support of others :D), that looks like this one:
<?php
$fh=fopen('uploads/datei.txt');
while(!feof($fh)){
$string = fgets($fh);
$array[1].=substr($string,2,9);
$array[2].=substr($string,19,9);
$array[3].=substr($string,28,9);
$array[4].=substr($string,37,8);
$array[5].=substr($string,45,9);
$array[6].=substr($string,99,5);
$array[7].=substr($string,104,2);
$array[8].=substr($string,108,18);
$array[9].=substr($string,300,18);
}
$new_variable = implode(';',$array);
echo $new_variable;
?>
What I have to do now, is to write these code slices into my data base (because currently it is only working for ONE line of 480 charakters), that has the following structure:
mysql_query(“CREATE TABLE datenimport (
id int(255) NOT NULL auto_increment,
kennung varchar(1) NOT NULL default ‘0’,
zusatzkennung varchar(1) NOT NULL default ‘0’,
buchungsdatum varchar(100) NOT NULL,
beleg varchar(8) NOT NULL,
buchungstext varchar(60) NOT NULL,
sollkonto varchar(100) NOT NULL,
habenkonto varchar(100) NOT NULL,
buchungsbetrag varchar(100) NOT NULL,
steuerbetrag varchar(100) NOT NULL,
steuersatz varchar(100) NOT NULL,
fwcode varchar(100) NOT NULL default ‘0’,
fwbuchungsbetrag varchar(100) NOT NULL,
fwsteuerbetrag varchar(100) NOT NULL,
nettozahlungsziel varchar(100) NOT NULL,
skontotage1 varchar(100) NOT NULL,
skonto1 varchar(100) NOT NULL,
skontotage2 varchar(100) NOT NULL,
skonto2 varchar(100) NOT NULL,
zessionsbank varchar(100) NOT NULL,
mahnen varchar(100) NOT NULL,
verzugszinsen varchar(100) NOT NULL,
bankeinzug varchar(100) NOT NULL,
valutadatum varchar(100) NOT NULL,
opnummernkostenstelle varchar(100) NOT NULL,
skontobetrag varchar(100) NOT NULL,
fwskontobetrag varchar(100) NOT NULL,
kore varchar(1) NOT NULL default ‘0’,
PRIMARY KEY (id) );”);
mysql_close();
So, there are only 9 slices, that are relevant for the output to the DB table.
The current output looks like:
000066202;000000000;000000012;01201310;00008060 ;00000;00;0000000000010540+0;OHN/01 L
But how?
