After I use array_unique() on an array, when I var_dump() the array, it still has the same content, with duplicates:
array(21) {
[0]=> string(10) "tricou_CRS"
[1]=> string(10) "tricou_CRM"
[2]=> string(11) "tricou_CRXL"
[3]=> string(10) "tricou_CBM"
[4]=> string(10) "tricou_CBL"
[5]=> string(10) "tricou_CWS"
[6]=> string(11) "tricou_CWXL"
[7]=> string(10) "tricou_CRS"
[8]=> string(10) "tricou_CRM"
[9]=> string(11) "tricou_CRXL"
[10]=> string(10) "tricou_CBM"
[11]=> string(10) "tricou_CBL"
[12]=> string(10) "tricou_CWS"
[13]=> string(11) "tricou_CWXL"
[14]=> string(10) "tricou_CRS"
[15]=> string(10) "tricou_CRM"
[16]=> string(11) "tricou_CRXL"
[17]=> string(10) "tricou_CBM"
[18]=> string(10) "tricou_CBL"
[19]=> string(10) "tricou_CWS"
[20]=> string(11) "tricou_CWXL" }
Which obviously has some duplicates. Now, there's not much code that could help, really, because it's just
array_unique($myarr);
var_dump($myarr);
So, what am I missing there? Shouldn't array_unique() remove the duplicates? Both the type and the content is the same in many of the array's positions.
$uniquearr = array_unique($myarr);
var_dump($uniquearr);
Always read docs first
array_unique
Return Values
Returns the filtered array.
