Sort an array by a child array's value
- by Evan
I have an array composed of arrays. I want to sort the parent array by a property of the child arrays. Here's an example
array(2) {
[0]=>
array(3) {
[0]=>
string(6) "105945"
[1]=>
string(10) "First name"
[2]=>
float(0.080878465391)
}
[1]=>
array(3) {
[0]=>
string(6) "109145"
[1]=>
string(11) "Second name"
[2]=>
float(0.0504154818384)
}
I would like to sort the parent array by [2] ascending in the child arrays, so in this case the result would be the child arrays reversed (.05, 08). Is this possible using any of the numerous PHP sort functions?
