I'm trying to recursively loop through a multi dimensional array with unknown keys and unknown values, and echo the keys/values to a sql statement, where the key is the field, and the value is the. value. What I want to do is test an array index to see if it has any children indices (which then need to be looped through again), or if it is the lowest level child. in which case, the data needs to be extracted. What is the easiest way to test an array index to see if it has one or more children? Just doing a count() isn't reliable, as their may only be a single parent on the highest level. John
