What is a hopelite?

What was one tactic used by the ancient Persians to defeat an assault by a hoplite battle formation?

Attacks by Hoplite infantry formations presented a dangerous battlefield situation for the ancient Persians. In situations where the Persians were relying on their light infantry, it became a challenge to defeat the hoplite heavy infantry attacks. One method was to establish an aray of archers some distance from a hopelite formation. Far enough away to prevent a spear attack, but close enough for archery arrows. With their light cavalry, the Persians would attack each flank of the hoplite formation. The cavalry attacks would force the hoplite formation to stop its march and defend each side of their formation. This allowed the large Persian archery force to shower the immobilized and distracted hopelites. The combined counter offensive of the Persians, the archers and the light cavalry would defeat the hoplite army.
