从多个csv读取特定的行和行，并导出到一个csv文件

Question

I receive weekly four csv files from four external sources. The csv files have the same design but contain different data. I would like to have specific rows and lines from all four files collected into one csv file.

Below is an example of how all four csv files is designed. I want to read Date, Name and Row5 and Row6 from all four csv files and then all this should be added into one csv file and set up as the 2nd example.

How could this be done? Within MS Excel as a script or maybe serverside using PHP? I have been looking into a solution PHP. But i am not sure if it's even possible using PHP?

The delimiters used in the content (row1,row2,row3 etc.) is a comma (,). The top with date and name only uses a colon (:)

Date: 24-01-2014                            
Name: source1

I hope someone here at Stackoverflow have an idea of how this could be done.

Answer 1

$foo = array( "source1.csv", "source2.csv","source3.csv","source4.csv");  
    $cont=0;
    foreach ($foo as $value) {
        $fh = fopen($value, 'r');
        if(!$fh) die('File no good!');

        $i=0;$j=0;
        while (!feof($fh )){
            $campo = fgetcsv($fh,4096,";");

            if($i < 2)
                $dataandsource[$cont][$i]=$campo[1];
            elseif($campo[5] != '' && $campo[6]!= ''){
                $rowfive[$cont][$j]=$campo[4];
                $rowsix[$cont][$j]=$campo[5];
                $j++;
            }
            $i++;
        }
        unset($rowfive[$cont][0]); //first row is 'row5'
        unset($rowsix[$cont][0]);  //first row is 'row6'
    $cont++;
    }
    for($x=0;$x< count($foo);$x++)
    {
        for($y=0;$y <= count($rowfive[$x]);$y++)
        {
            if($x==0 && $y ==0)
                echo "row5  row6  Date    Source<br>";
            else{
                if($rowfive[$x][$y] != '' )
                echo $rowfive[$x][$y].";".$rowsix[$x][$y].";".$dataandsource[$x][0].";".$dataandsource[$x][1]."<br>";
            }

        }
    }

i made this code with 4 csv file, with this information:

Date;24/01/2014;;;;;;;
Name;source1;;;;;;;



Row1;   Row2;   Row3;Row4;  Row5;Row6;Row7;Row8;Row9
ad4213;ad4214;ad4215;ad4216;ad4215;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4217;ad4218;ad4219;ad4220;ad4221
ad4213;ad4214;ad4215;ad4216;ad4215;ad4218;test6;ad4220;ad4221

and the result is something like you want:

row5 row6 Date Source
ad4215;ad4218;24/01/2014;source1
ad4217;ad4218;24/01/2014;source1
