Ich entwickle eine Website, die HTML Valid Tags verwendet, die in einem Array gespeichert sind, um sie mit den Eingaben der Benutzer in das System zu vergleichen. Ich habe derzeit das Array entwickelt, das alle HTML-Tags enthält, die ich benötige. Ich habe auch eine Funktion entwickelt, die die Benutzereingabe gegen Daten validiert, die innerhalb des Arrays gespeichert sind.Suche in meinem Array nach Werten, die ein bestimmtes Zeichen enthalten
Wenn es gültig ist, teilt es dem Benutzer mit, dass es akzeptiert wurde, und das gültige Tag wird dann in ein anderes Array eingefügt, das alle Tags enthält, die der Benutzer eingegeben hat.
Allerdings habe ich versucht, die Funktionalität zu erstellen, dass, wenn der Benutzer die Tags innerhalb des Systems eingibt, das Array nach Tags mit einem umgekehrten Schrägstrich gesucht wird/da dies alle schließenden Tags innerhalb des Arrays identifizieren wird.
Also meine Frage wäre, wie ich alle Datensätze innerhalb meiner AllowedTags Array extrahieren würde, die ein/Character enthalten und diese in einem neuen Array speichern.

Was stimmt nicht mit dem Code, der '$ ret' setzt? – Barmar
Sie sollten die Funktion array_filter() verwenden. –
Warum verwenden Sie 'array_keys()' auf das Ergebnis von 'array_filter()'? Wenn Sie die Liste der Tags haben wollen, gibt 'array_filter()' es zurück. – Barmar
