21.12 Textfelder variabler Länge verarbeiten

Problem

Sie wollen unterteilte Textfelder aus einer Datei auslesen. Vielleicht haben Sie ein Datenbankprogramm, das die Datensätze in jeweils einer Zeile ausdruckt und Tabulator-Zeichen zwischen den Feldern eines Datensatzes einfügt. Sie wollen diese Informationen in ein Array kopieren.

Lösung

Lesen Sie jede Zeile ein und teilen Sie sie dann an den Begrenzungszeichen in die Felder auf:

$delim = '|';

$fh = fopen('books.txt','r') or die("Öffnen nicht möglich: $php_errormsg");
while (! feof($fh)) {
    $s = rtrim(fgets($fh,1024));
    $fields = explode($delim,$s);
    // ... etwas mit den Daten machen ...
}
fclose($fh) or die("Schließen nicht möglich: $php_errormsg");
