Create multidimensional array unique for any single key index.
e.g I want to create multi dimentional unique array for specific code
Code :
My array is like this,
<?php
$details = array(
0 => array("id"=>"1", "name"=>"Mike", "num"=>"9876543210"),
1 => array("id"=>"2", "name"=>"Carissa", "num"=>"08548596258"),
2 => array("id"=>"1", "name"=>"Mathew", "num"=>"784581254"),
);
?>
You can make it unique for any field like id, name or num.
I have develop this function for same :
<?php
function unique_multidim_array($array, $key) {
$temp_array = array();
$i = 0;
$key_array = array();
foreach($array as $val) {
if (!in_array($val[$key], $key_array)) {
$key_array[$i] = $val[$key];
$temp_array[$i] = $val;
}
$i++;
}
return $temp_array;
}
?>
Now, call this function anywhere from your code,
something like this,
<?php
$details = unique_multidim_array($details,'id');
?>
Output will be like this :
<?php
$details = array(
0 => array("id"=>"1","name"=>"Mike","num"=>"9876543210"),
1 => array("id"=>"2","name"=>"Carissa","num"=>"08548596258"),
);
?>
