Question

I am not able to sort this array of object. please kindly help. I am using usort for sorting the array.

Also I am getting this error:

PHP Parse error: syntax error, unexpected '=>' (T_DOUBLE_ARROW), expecting ')' in /home/cg/root/128245/main.php on line 7

I need to sort this array by the order of job_name attribute of my class.

@Krish yes kudos.but see my array format is different . how did u convert it.dts y its not working. you have used qoute for key and value .how did you convert it?or statically u converted it — Jeevanjyothi, Jun 19 '19 at 18:25
This looks like an output from a `print_r()` call, that's not how you define an array. That's the syntax error. — Rikudou_Sennin, Jun 19 '19 at 18:31
@Rikudou_Sennin i got this from mongo find.then i did json_decode and encode and got above data — Jeevanjyothi, Jun 19 '19 at 18:34
@Jeevanjyothi Well, that's not an output from `json_decode()`, it's from a `print_r()` call, you can't assing a result from `print_r()` to a variable. — Rikudou_Sennin, Jun 19 '19 at 18:36
@Jeevanjyothi, @Rikudou gave you maximum possible answers, try using output of `json_decode()` not `print_r()` — Krish, Jun 19 '19 at 18:40

Use usort function. You need to create a rule that your objects can be compared with each other. It is how it's used:

function compareObjects( $a , $b )
{
    return strcmp( $a->job_name , $b->job_name );
}

usort( $gfg_array , "compareObjects" );

Also you have a syntax error in your code and you need to set array values as strings as below:

is that array is correct.when am trying to run its showing :PHP Parse error: syntax error, unexpected '=>' (T_DOUBLE_ARROW), expecting ')' in /home/cg/root/128245/main.php on line 7 — Jeevanjyothi, Jun 19 '19 at 17:39
when i am using $gfg_array1 =Array ( Array ( 'score' => '100', 'name' => 'b', 'subject' => 'Data Structures' ), Array ( 'score' => '100', 'name' => 'a', 'subject' => 'Data Structures' ) ); sorting is working fine — Jeevanjyothi, Jun 19 '19 at 18:21
but for $gfg_array =Array ( [0] => Array ( [score] => 100 [name] => b [subject] => Data Structures ) [1] => Array ( [score] => 100 [name] => a [subject] => Data Structures ) ); sorting is not working — Jeevanjyothi, Jun 19 '19 at 18:21
Your Array structure is wrong in the second case. Why don't you use it like the first case that works? — Alireza A2F, Jun 19 '19 at 18:44
You need to add double quotes before ` SUCCESS` and time and other values you're adding to the array. — Alireza A2F, Jun 19 '19 at 20:44

You can try this function..

    function multisortByKeyValue( $k, $arr ) {
        $ids   = array();
        $index = 1;

        foreach ( $arr as $key => $row ) {
            $ids[ $key ] = intval( $row[ $k ] ) . '-' . $index . '-' . $key;
            $index ++;
        }

        natsort( $ids );

        $arr = array_merge( $ids, $arr );

        return $arr;
    }
```
