Unique Array

[AliceH]

Do you guys know of a php function that returns true if all the values in a specified array are unique?

[LordShryku]

array_unique will remove duplicate values from an array

array_diff_assoc can compute differences in array, and spit back the non unique results. So you can copy your array , and compare one to the other to get back non-unique results

...and [man]array_count_values[/man] will count the number of times each value appears in the array; if they're all unique, then the result will be the same length as the original, and all the array values will be 1.

PHP has lots and lots of array manipulation functions. Have fun.
