PHP - How to compare arrays are equal?

Question

I search the records in a table and put them in an array. I search the records in another table and put them in another array. When the number of query rows in each table are the same, and the arrays are the same, the code is able to identify equality.

different lines

When the number of query rows in one table is different from the query in the other table, even though the arrays are the same, the code identifies it as different.


//Query1
while(){
 $vetor_xml[$cfop] += $vTotal;
}

//Query2
while(){
 $vetor_c190[$cfop] += $aux_vl_opr;
}


function identical_values( $arrayA , $arrayB ) {

    ///sort( $arrayA );
    ///sort( $arrayB );

    return ($arrayA == $arrayB);
}


$r = identical_values( $vetor_xml, $vetor_c190);
var_dump($r);

if(($vetor_xml=== $vetor_c190)==false){
 echo "ERROR";
}
else{
 echo "OK";
}

@rafaelspfonseca - If you're using the equality checks correctly, you won't have a problem. Please post the code and data necessary to reproduce the error you're getting, and we can try to help. Without a reproducible example, we cannot help you. — fubar, Jul 29 '20 at 01:14

Try using array_diff

$array1 = array("a" => "sky", "star", "moon", "cloud", "moon");
$array2 = array("a" => "sky", "star", "moon", "cloud", "moon");

// Comparing the values
$result = array_diff($array1, $array2);
if(empty($result)){
    //array are equal
}else{
   //array are not equal
   //you can print the difference 
}

You have two array `$vetor_xml` and `$vetor_c190` . Use `array_diff`, If function return empty array then it is equal else not equal. This may probably help. – Suresh Chand Jul 29 '20 at 01:07
`array_diff` not workink [link]https://www.imagemhost.com.br/image/xeJTJ – rafaelspfonseca Jul 29 '20 at 01:20
If `$array2` has everything in `$array1`, and also has extra elements, this will say they're equal. – Barmar Jul 29 '20 at 01:46
key and value must be equal in both arrays – rafaelspfonseca Jul 29 '20 at 01:54

Resolved! Follows solution.

function identical_values( $arrayA , $arrayB ) {

    ///sort( $arrayA );
    //sort( $arrayB );

    return ($arrayA == $arrayB);
}


$res = identical_values( $vetor_xml , $vetor_c190 );

$result = array_diff_assoc($vetor_xml, $vetor_c190);//add new verification
   
  
if(($tem_xml>0)&&(empty($res))) {

   //add new verification here
   if(empty($result)){
      echo"<p><b>EQUAL</b>";
   }
   else{
      echo "<p><b>NOT EQUAL</b>";
      $divergencia++;
   }
}

else{
    echo"<p><b>EQUAL</b>";
}
