Comparing strings in PHP and removing one of them from the array if they are similar

[priceorchid]

Let say I have an array like this:

• Band of Horses - Is There a Ghost
• Band Of Horses - No One's Gonna LoveYou
• Band of Horses - The Funeral
• Band of Horses - The Funeral (lyricsin description)
• Band of Horses - Laredo
• Band Of Horses - Laredo on Letterman5.20.10
• Band of Horses - "The Great SaltLake" Sub Pop Records
• Band Of Horses - "No One's Gonna LoveYou"
• Band of Horses perform Marry Song atTromso Wedding
• Band Of Horses - No One's Gonna LoveYou
• 'Laredo' by Band of Horses on Q TV
• Band of Horses, On My Way Back Home
• Band of Horses - cigarettes weddingbands
• Band Of Horses - "Cigarettes WeddingBands"
• Band Of Horses - I Go To The BarnBecause I Like The
• Our Swords - Band of Horses
• Band Of Horses - "Marry song"
• Band of Horses - Monsters
• Band Of Horses - No One's Gonna LoveYou

The New Array would have:

• Band of Horses - Is There a Ghost
• Band Of Horses - No One's Gonna LoveYou
• Band of Horses - The Funeral
• Band of Horses - Laredo
• Band of Horses - "The Great SaltLake" Sub Pop Records
• Band of Horses, On My Way Back Home
• Band of Horses - cigarettes weddingbands
• Band Of Horses - I Go To The BarnBecause I Like The
• Our Swords - Band of Horses
• Band Of Horses - "Marry song"
• Band of Horses - Monsters

How would you go about comparing each string to every other string in the list in PHP and if they are similar, remove them.I consider these similar:

• Band of Horses - The Funeral
• Band of Horses - The Funeral (lyrics in description)

Another example:

• Band of Horses - Laredo
• Band Of Horses - Laredo on Letterman5.20.10
