An immobile, faintly shimmering magical sphere surrounds you and excludes all spell effects of 4th level or lower, including Spell-Like Abilities and spells or spell-like effects from items. The area or effect of any such spells does not include the area of the Globe of Invulnerability. Such spells fail to affect any target located within the globe. Any type of spell, however, can be cast through or out of the magical globe. Spells of 5th level and higher are not affected by the globe, nor are spells already in effect when the globe is cast. The globe can be brought down by a dispel magic spell. You can leave and return to the globe without Penalty.

Note that spell effects are not disrupted unless their effects enter the globe, and even then they are merely suppressed, not dispelled.

If a given spell has more than one level depending on which character class is casting it, use the level appropriate to the caster to determine whether globe of invulnerability stops it.
