PHP-Code:

<?php
error_reporting (E_ALL & ~E_NOTICE);
include_once("datenbank_verbindung.php");    
$ergebnis = mysql_query("SELECT * FROM tabelle");
while($row = mysql_fetch_object($ergebnis))
{
      
echo "<b>$row->spalte1 --- $row->spalte2</b><br>";

$str = $row->spalte3;
$search = "suchwort";

$pos = strpos($str, $search);
 
$substr = substr($str, $pos - 10, 115); 

echo $substr;

echo "<br>";

}
?>

Mein Code zeigt leider nur das erste / oder ein einziges Vorkommen von suchwort in spalte3 an (mit 10 Zeichen davor und 97 Zeichen danach, ich möchte aber alle Vorkommen anzeigen lassen. Kann jemand meinen Code ergänzen und den fehlenden / anderslautenden Code vollständig posten. Also bitte nicht nur Schnipsel.
Danke.

Fertigen Code wird gewünscht? Ab zur Jobausschreibung

@ YASLAW

Wer wie ich als Nutzer unterwegs ist um Quellenstudium für eine Diplomarbeit besser betreiben zu können und deshalb möglichst auf einfache Weise dazu noch simpelste Codes sucht weil er so gut wie keine Ahnung von php hat, der hat sicherlich keine Lust noch lange bittebitte zu machen oder gar mit Schnipseln rumzuprobieren.

Wenn Du mal was zum Thema Controlling und Warenwirtschaft brauchst bin ich sicherlich bereit umfänglicher zu antworten. Das ist nämlich mein Berufsschwerpunkt.

Ich wüsste auch gar nicht was ein paar Zeilen mit einem Job zu tun haben.

Schon "schlimm" genug das ich als Rookie bezeichnet werde

Wer sagt denn, das im Jobforum nur nach bittebitte geholfen wird. Aber hier weiss man, dass jemand eine fertige Lösung und keine Lösungsdiskusion wünscht.

Zum Thema. Wie sieht denn so ein zu zerlegender String aus? Mach mal ein Beispiel eines Eingangstrings und die dazugehörenden gewünschten Resultate.

Im Moment suche ich in einer mysql-DB in der in einer spalte (in meinem Script spalte3) Produkte der Warengruppe GPK (Glas Porzellan Keramik) beschrieben sind. Darin enthalten sind auch Herstellungsbeschreibungen die gleich am Anfang beschrieben sind. Diese Teil-Informationen will ich aber gar nicht "studieren". Bei meiner Abfrage wird leider scheinbar immer nur das erste Vorkommen angezeigt, also eines zum Beschreibungsbereich den ich eben nicht "studieren" will.
Also wäre es einfacher alle Vorkommnisse anzuzeigen um die brauchbaren erkennen zu können.

Als Suchwort benutze ich zB das Wort "Glasschale" (oder "Glasschalen"). Die Ergebnisse sind dann Textstellen in denen das Suchwort vorkommt. Daran erkenne ich ob ich den gesamten Inhalt der spalte ansehen und "studieren" sollte. Die gesuchten Textstellen zeichnen sich nicht technisch aus sondern inhaltlich, sie erhalten nämlich Infos zum Thema Logistik(Transport/Lagerung). Mein Fachbereich.

Vielleicht noch wichtig: Teilweise sind es einzelne Webseiten von Herstellern, Händlern, Speditionen etc. die html-tags, javascripts usw. enthalten.

Das bewirkt leider daß auch tags angezeigt werden, dieses Problem habe ich in diesem Forum auch schon "ausgeschrieben". Bin aber bisher auch gescheitert.
Nur "Klartext" wäre halt besser.

Also wie ich es verstehe ahst du in einem Feld in der DB Texte (ganze HTML-Seiten). Diese willst du durchsuchen ob das Wort darin vorkommt.

Das kannst du mit WHERE lösen

Code sql:

1	SELECT * FROM myTable WHERE field3 LIKE "*myWord*";

Sorry, da soviel unklar in deinen Anforderungen ist, ist es nicht möglich wie von dir gewünscht eine fertige Lösung zu presentieren

Ist eigentlich ganz einfach. Das was Du schreibst kenn ich ja, aber sieh mal wie oft Stellen mit dem Wort Suchwort glas vorkommen, bei dieser Beispielsseite von Schott Glas. Der gesamte Inhalt ist der Wert in spalte3. manchmal sind es aber auch Inhalte von einfachen .txt-Seiten oder oder

Ich hab mal einige Fundstellen für glas rausgeschrieben:

1. <title>Flat Glass - SCHOTT® Flat Glass für di ...
2. Flat Glass für die Küche | SCHOTT AG</title> ...
3. flachglas, glas, glasfronten, glasküche, küche ...
4. glas, glasfronten, glasküche, küche, kücheng ...
5. glasfronten, glasküche, küche, küchenglas, s ...

Bei meinem Code wird mir aber nur die Fundstelle 1.) angezeigt. Alle weiteren nicht mehr. Ich will aber alle sehen.

Dann kann ich sehen ob der Datenbankeintrag, in diesem Falle die Seite von Schott Glas, für mich relevant ist.

Thats it.

ah, jetzt versteh ich was du willst.

Das löst man mit einer Schleife

PHP-Code:

$pos = 0;
while($pos = stripos($str, $search, $pos+1)){
    echo substr($str, $pos - 10, 115).'<br />';
} 


Danke alles fast klar. Aber kann es sein das jetzt nur die(alle) Vorkommen aus dem einem (dem ersten gefundenen) Datenbankeintrag angezeigt werden, aber nicht aus allen Datenbankeinträgen?
Das Suchwort glas finde ich in 11.987 Datenbankeinträgen gesamt, erster Eintrag mit id 33.369.
Mit dem neuen Code finde ich nur alle Vorkommnisse in Datenbankeintrag mit id 33.369.



Jetzt wäre noch schön zu wissen wie ich aus den Werten wie html-Seiten die tags entfernen kann weil die Ergebnisse wegen der tags teilweise ziemlich "schräg" sind.

Vielleicht mit strip_tags aber da habe ich gehört das geht nicht vollkommen. Mir wäre aber auch gedient mit der Entfernung von Teilbereichen wie allem zwischen <head> und </head>. Ich weiß es gibt sql-Code mit replace oder ähnlich aber angeblich muß man regex nehmen. Weiß Gott wie das geht.

Problem ist also: Wie kann ich alle tags restlos entfernen oder wie kann ich zumindest große Teile entfernen wie alles zwischen <head> bis </head>.

Einen Code-Schnipsel habe ich gefunden: preg_replace('/<head>.*?<\/head>/', 'blablabla', $spalte3)

Jepp, mein Code geht nur einen Record durch. Du musst ihn natürlich innerhalb deiner while-Schleife schreiben

PHP-Code:

$search = "suchwort";
while($row = mysql_fetch_object($ergebnis)){
    $pos = 0;
    while($pos = stripos($row->spalte3, $search, $pos+1)){
        echo substr($row->spalte3, $pos - 10, 115).'<br />';
    }  
} 


PHP-Code:

<?php
error_reporting (E_ALL & ~E_NOTICE);
include_once("verbindung.php");    
$ergebnis = mysql_query("SELECT * FROM seiten");

$search = "glas";

while($row = mysql_fetch_object($ergebnis)){
    $str = $row->inhalt;
    $pos = 0;
    while($pos = stripos($str, $search, $pos+1)){
        echo "<b>HIER:</b>   ".substr($str, $pos - 10, 115)."<br />";
    }  
} 
?>

Danke, da kommt leider das selbe bei raus. Hatte wohl vorher alles auch schon in der Schleife. Nur der erstgefundene Datensatz mit Suchwort glas in spalte inhalt wird durchsucht und alle Vorkommnisse darin werden angezeigt.
