As I understand "If one operation is wrong then the whole transaction is wrong"
Trying to find the cause 'op_malformed'
I already read it "Transaction Malformed" I never found a mistake
This is operations [2] in transaction:
[2] => ZuluCrypto\StellarSdk\XdrModel\Operation\ManageOfferOp Object

this is horizon response:

)
maybe there is an error:
[buyingAsset:protected] => ZuluCrypto\StellarSdk\XdrModel\Asset Object
(
[type:ZuluCrypto\StellarSdk\XdrModel\Asset:private] => 0
[assetCode:ZuluCrypto\StellarSdk\XdrModel\Asset:private] =>

)
Many thanks to all for help in finding the error. @sui @Synesso
The price in stellar is displayed as a simple fraction in which you need to transfer your decimal, and publish it in the form: numerator and denominator separately. (int) numerator, (int) denominator.
I tested a lot of functions for finding the minimum fraction for converting from decimal, this is what I found / added (PHP code):
function float2fraction($n, $tolerance = 1.e-9) {
/* www.mera.one, stellar price float2fraction function - return numerator / denominator */
$n = (float) $n;
$h1=1; $h2=0;
$k1=0; $k2=1;
$b = 1/$n;
do {
$b = 1/$b;
$a = floor($b);
$aux = $h1; $h1 = $a*$h1+$h2; $h2 = $aux;
$aux = $k1; $k1 = $a*$k1+$k2; $k2 = $aux;
$b = $b-$a;
} while (abs($n-$h1/$k1) > $n*$tolerance);
if ( ! empty ( $h1 ) && ! empty ( $k1 ))
return array ( "nominator" => $h1, "denominator" => $k1, "str_view" => "$h1/$k1" ) ;
else
return false;
}
ps: I also received an error from the ZuluCrypto class "error code 3 in CreateAccountResult.php", adding this code to the $errorCodeMap program began to run. In ZuluCrypto itself, it’s just about writing errors when working with floating point ("Floating point issues")
