how to pass the two array? - php

Question

The test.php directory is the same as csv and text file. now i want to pass all the csv file name and all the text name to the following if condition. namely, replace one.csv with all the csv file name. replace one.txt with all the txt file name.
if (($handle = fopen("one.csv", "r")) !== FALSE && ($handle2 = fopen("one.txt", 'a')) !== FALSE) { ...}
the following is my code. after run the code,i found all the content in the text file are the same. it loops too many times. how to change the code?thank you.
$files = glob("./*.csv");
$files1 = glob("./*.txt");
foreach($files as $filepath){
foreach($files1 as $filepath1){
$row = 1;
if (($handle = fopen("one.csv", "r")) !== FALSE && ($handle2 = fopen("one.txt", 'a')) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($row > 1) {
$url = $data[8];
foreach($result[0] as $url){
fwrite($handle2, $url."\r\n");
}
}
$row++;
}
fclose($handle);
fclose($handle2);
}
}
}
The txt file is empty. now, i want to read the csv file and extract some content of it then put them into the text file. thank you

Answer 1

You don't need to glob .txt files, just glob csv, and replace the extension .csv by .txt
$csv = glob('./*.csv');
foreach($csv as $file) {
$txt = preg_replace('#\.csv$#', '.txt', $file);
if (($handle = fopen($file, "r")) !== FALSE && ($handle2 = fopen($txt, 'a')) !== FALSE) {
//your code...
}
}

The problem is that you've got a loop within a loop. So every time the first loop loops it's doing everything in the second loop AGAIN.
Try something like this:
$csv_files = glob("./*.csv");
$txt_files = glob("./*.txt");
$csvs = array();
foreach($csv_files as $fp){
$csvs[] = fopen($fp, "r");
}
$txts = array();
foreach($txt_files as $fp){
$txts[] = fopen($fp, "r");
}
var_dump($csvs); // all csv file info
var_dump($txts); // all txt file info
You can test to see !== false in the separate loops if you wish. Otherwise, if you just want to use them then you can loop through the separate arrays and get the info out of them that way.
