Il codice PHP che segue in ambiente locale (con WampServer installato) funziona correttamente, su Altervista no, qualche consiglio?
Codice:<!DOCTYPE html> <html> <head> <title>Aggiunge 10 davanti i codici che non lo presentano già</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <body> <?php $file_path_into_array = glob("/myfolder/*.txt"); $file_path = $file_path_into_array[0]; $file = fopen($file_path, "r+"); $file_in_row = file($file_path); $i = 0; foreach ($file_in_row as $row_content){ if ($i > 0) { $char = substr($row_content, 94, 11); if(strlen(trim($char)) == 11){ $new_row_content[] = $row_content; } else if(strlen(trim($char)) != 0){ $new_row_content[] = str_replace($char, "10$char" - 2, $row_content); } } else if($i == 0) { $new_row_content[] = $row_content; } $i++; } fclose($file); $string = implode("\n", $new_row_content); $new_file = fopen($file_path, "w+"); fwrite($new_file, $string); fclose($new_file); echo "Ho creato un nuovo file: <b>$file_path<b>"; ?> </body> </html>
