Getting error in executing Stored Proc from PHP - php

Question

I am new to MSSQL Server and there's a stored proc created by some developer and all I need to is run the proc from my PHP code.
But I am getting below error
The formal parameter "#contract_id" was not declared as an OUTPUT parameter, but the actual parameter passed in requested output.
Below is my code
$params['contract_id'] = '00990007';
$params['major_version'] = '1';
$procedure_params = array(
array(&$params['contract_id'], SQLSRV_PARAM_OUT),
array(&$params['major_version'], SQLSRV_PARAM_OUT)
);
$sql = "EXEC [MTP].[Process_07a_create_a_contract_version_wrapper] #contract_id = ?, #major_version = ?";
$stmt = sqlsrv_prepare($conn, $sql, $procedure_params);
if( !$stmt ) {
die( print_r( sqlsrv_errors(), true));
}
if(sqlsrv_execute($stmt)){
while($res = sqlsrv_next_result($stmt)){
// make sure all result sets are stepped through, since the output params may not be set until this happens
}
// Output params are now set,
}else{
die( print_r( sqlsrv_errors(), true));
}
Can anyone guide me on this please?

First, check the type and the order of parameters, using sys.parameters. Then set params using the results:
<?php
...
$sql =
"SELECT [name], [is_output]
FROM sys.parameters
WHERE object_id = object_id('[MTP].[Process_07a_create_a_contract_version_wrapper]')
ORDER BY parameter_id";
$res = sqlsrv_query($conn, $sql);
if ($res === false) {
echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
exit;
}
while ($row = sqlsrv_fetch_array($res, SQLSRV_FETCH_ASSOC)) {
echo 'Name: '.$row['name'].', ';
echo 'Output: '.($row['is_output'] == 1 ? 'Yes' : 'No');
echo '</br>';
}
...
?>
Error message "The formal parameter "#contract_id" was not declared as an OUTPUT parameter, but the actual parameter passed in requested output" can be raised when the #contract_id parameter is not output parameter. So you can try with this (using your code):
<?php
...
$sql = "{call [MTP].[Process_07a_create_a_contract_version_wrapper](?, ?)}";
$procedure_params = array(
array($params['contract_id'], SQLSRV_PARAM_IN),
array(&$params['major_version'], SQLSRV_PARAM_INOUT)
);
$stmt = sqlsrv_query($conn, $sql, $procedure_params);
if( $stmt === false ) {
echo "Error (sqlsrv_query): ".print_r(sqlsrv_errors(), true);
exit;
}
// Output parameters are available after consuming all resultsets.
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
}
...
?>
