In a varibale I have the repeated values
$variable= "1,2,3,4,5,6,7,8,9,1,2,3,4,8,9,1,2,3";
there is some php functionality that allows to eliminate the repeated values =
I did the test with array_unique($variable);
but I get a mistake when I take the test
We convert the string to array with explode and then pass the array to array_unique I leave you with an example:
$variable= '1,2,3,4,5,6,7,8,9,1,2,3,4,8,9,1,2,3';
$a_val = explode(',',$variable);
$a_result = array_unique($a_val);
The variable $ a_result would be array without duplicates. If you want to pass the array again to a string you use the implode method, I'll give you the example:
$varible = implode(",",$a_result);
Assuming that parts of a string that consists of numbers separated by commas, you should do the following:
1-Convert the string into an array with the function explode which is responsible for converting a string in array given a delimiter, in this case the comma:
$variable= "1,2,3,4,5,6,7,8,9,1,2,3,4,8,9,1,2,3";
$array = explode(",",$variable);
2- Eliminate the repeated values of the array with the function array_unique :
$array=array_unique($array);
3-Re-convert the array in string with the function implode that converts an array in string separated by the given delimiter:
$variable=implode($array,",");
result:
1,2,3,4,5,6,7,8,9
First you must convert it into an array since the array_unique expects as input the information in data type array
$variable= "1,2,3,4,5,6,7,8,9,1,2,3,4,8,9,1,2,3";
$variable= = explode(",", $variable);
So later you can apply as well you mention the array_unique($variable);
