Om het escapen met een \ van de HTML "-quotes te voorkomen kan je beter een echo gebruiken met een single-quote ( ' ). Het is eigenlijk nog beter om hele lappen HTML buiten je PHP-blok te houden.

Nee dat zijn dubbele-quotes, geen single-quotes.
Of doe makkelijker, zonder het mengen van HTML in PHP.

thanks!
Natuurlijk zijn er ook uitzonderingen waarbij dit niet altijd helemaal netjes opgaat, maar in het algemeen werkt dit vrij goed.
Het is mijn ervaring dat dit, als je eenmaal in deze "modus" zit, de leesbaarheid van code (enorm) bevordert.
Toegepast op het bovenstaande stuk code wordt dit, na enige fatsoenering:

Ook zou ik je aanraden je (verder) te verdiepen in character encod(er)ing(en) en het escapen van output. Dit gaat op den duur een grote en belangrijke rol spelen wanneer je van dit soort administratieve systemen aan het bouwen bent. Indien niet of verkeerd toegepast kan dit tot heel veel hoofdpijn en/of veiligheidslekken leiden.
