how the php is making error while opening and writing to the file.
function makeImage() {
$encoded_string = $_POST['encoded_string'];
$decoded_string = base64_decode($encoded_string);
$path = "C:\Inetpub\vhosts\apbclt.com\httpdocs\php\logo".$_POST['company_name'];
$file = fopen($path, 'wb');
$is_written = fwrite($file, $decoded_string);
fclose($file);
if($is_written > 0) {
global $mysqli;
$stmt = $mysqli->prepare("INSERT INTO Companies (logo) VALUES (?)");
$stmt->bind_param("s", $path);
$stmt->execute();
$stmt->store_result();
if($stmt->affected_rows > 0) {
$stmt->close();
return true;
}else{
$stmt->close();
return false;
}
}
}
and here is the error
PHP Warning: fopen(C:\Inetpubhosts\apbclt.com\httpdocs\php\logo): failed to open stream: Invalid argument in C:\Inetpub\vhosts\apbclt.com\httpdocs\php\create_company.php on line 54

PHP Warning: fclose() expects parameter 1 to be resource, boolean given in C:\Inetpub\vhosts\apbclt.com\httpdocs\php\create_company.php on line 56
I searched SO but no answer to my case.
Update ::
when I changed the \v to \v like the first answer i got the following error.
PHP Warning: fopen(C:\Inetpub\vhosts\apbclt.com\httpdocs\php\logo): failed to open stream: Permission denied in C:\Inetpub\vhosts\apbclt.com\httpdocs\php\create_company.php on line 54

ok I solved the issue instead of using the full file path I just used the path by going back a folder ..\logo
This is the php java script to run on webserver. In it i will get input from android app the query is
<?php
$mysqlDebug = true;
//create connection
print "hello 1";
mysql_connect("localhost", "pu", "Ind");
print "hello 2";
mysql_select_db("leengage");
print "hello 3";
print mysql_error();
// Check connection
if (mysql_error())
{
echo "Failed to connect to MySQL: " . mysql_error();
print "hello 4";
}
print "hello 5";
mysql_query("INSERT INTO details_master(name ,phone, email, birthdaydate, birthdaymonth, anniversarydate, anniversarymonth,created)
VALUES ('Peterr', 'Griffinn','hello#hello.com',12,12,12,12,'0000-00-00 00:00:00')");
print mysql_error();
// escape variables for security
print "hello 7";
$name = mysql_real_escape_string($conn, $_POST['name']);
$phone = mysql_real_escape_string($conn, $_POST['phone']);
$email = mysql_real_escape_string($conn, $_POST['email']);
$birthdaydate = mysql_real_escape_string($conn, $_POST['birthdaydate']);
$birthdaymonth = mysql_real_escape_string($conn, $_POST['birthdaymonth']);
$anniversarydate = mysql_real_escape_string($conn, $_POST['anniversarydate']);
$anniversarymonth = mysql_real_escape_string($conn, $_POST['anniversarymonth']);
$created = mysql_real_escape_string($conn, $_POST['created']);
$sql = "INSERT INTO details_master(name ,phone, email, birthdaydate, birthdaymonth,
anniversarydate, anniversarymonth,created)
VALUES ('$name','$phone', '$email', '$birthdaydate', '$birthdaymonth', '$anniversarydate',
'$anniversarymonth', '$created')";
print "hello 8";
if (!mysql_query($conn, $sql))
{
die('Error: ' . mysql_error($conn));
}
echo "1 record added";
?>
The first insert query is running fine and inserting records from app but second insert query is not working it gives following errors.

Just in case I am getting input from android app and code i am using for this is on create:
StrictMode.ThreadPolicy policy = new
StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
And on button click is:
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
// define the parameter
postParameters.add(new BasicNameValuePair("name",name));
postParameters.add(new BasicNameValuePair("phone",phone));
postParameters.add(new BasicNameValuePair("email",email));
postParameters.add(new BasicNameValuePair("birthdaydate",s1));
postParameters.add(new BasicNameValuePair("birthdaymonth",s2));
postParameters.add(new BasicNameValuePair("anniversarydate",s3));
postParameters.add(new BasicNameValuePair("anniversarymonth",s4));
postParameters.add(new BasicNameValuePair("created",formattedDate));
String response = null;
try {
response = CustomHttpClient.executeHttpPost("http://purplefront.net/PurpleEngage/mydatainsert.php", postParameters);
// store the result returned by PHP script that runs MySQL query
String result = response.toString();
//parse json data
Log.d("result data", result);
}
catch (Exception e) {
Log.e("log_tag","Error in http connection!!" + e.toString());
}
You keep referencing $conn, which doesn't appear to be set anywhere. It looks like you're trying to use mysqli_ syntax (connection object, then sql) with mysql_ functions (which use the last opened connection)
This answer assumes you convert all your calls to mysqli_ (you can't mix and match) but this should point you in the right direction
$conn = mysqli_connect("localhost","pu","Ind");
$name = mysqli_real_escape_string($conn, $_POST['name']);
if (!mysqli_query($conn,$sql)) {
die('Error: ' . mysqli_error($conn));
}
I've decided to using mysqli instead of mysql and I've having some errors, this is my first time using mysqli and I don't know what the errors are, any suggestions?

function query($query) {
$sql = mysqli_query($query, $this->db) or die(mysqli_error());
return $sql;

function fetch($query) {

Try this, You have used mysql_query instead of mysqli_query
function query($query) {
$sql = mysqli_query($this->db, $query) or die(mysqli_error());
...
}
function fetch($query) {
mysqli_fetch_array(mysqli_query($this->db, $query));
....
}
instead of
function fetch($query) {
mysqli_fetch_array(mysql_query($query, $this->db));
...
}
Try using a mysqli_query() function like this maybe
$data = mysqli_query($dbc, $query);
mysqli_fetch_array($data)
Notice that with mysqli_query() two arguments are passed:
the database connection variable
the query variable
Then use the the result of the mysqli_query() function as the argument to mysqli_fetch_array() function :D
As there is not ready made function in oracle to validate the Query so created.
So I tried below code to check whether the QUERY is valid or not.
if(isset($_POST['btn_Submit_Query']))
{
$check_query=$_POST['txtQuery'];
echo $check_query;
$valid = false;
$stmt = oci_parse($DB, $check_query);
echo "Statement" . $stmt;
//oci_define_by_name($stmt, 'NUMBER_OF_ROWS', $number_of_rows);
oci_execute($stmt, OCI_DEFAULT);
echo oci_num_rows($stmt);
}
I got following Warnings in the Execution:
Warning: oci_parse() expects parameter 1 to be resource, object given in D:\xampp\htdocs\app\DashBoardSite\Admin\querybuilder.php on line 899
Statement
Warning: oci_execute() expects parameter 1 to be resource, null given in D:\xampp\htdocs\app\DashBoardSite\Admin\querybuilder.php on line 902

Where is my mistake?
You must first connect to the database. This connection must a "resource" to variable $DB.
I'm trying to save the data retrieved from the database into a .json. This is what is just tried.
$sql = mysql_query("SELECT `positive`,`time` FROM sentiment WHERE acctid=1");
$response = array();
$posts = array();
while($row=mysql_fetch_array($sql))
{
$positive=$row['positive'];
$time=$row['time'];
$posts[] = array('positive'=> $positive, 'time'=> $time,);
}
$response['posts'] = $posts;
$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($response));
fclose($fp);
I got the following errors:
Warning: fopen(results.json) [function.fopen]: failed to open stream: Permission denied in /Applications/XAMPP/xamppfiles/htdocs/test/getjson.php on line 29
Warning: fwrite() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/test/getjson.php on line 30
Warning: fclose() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/test/getjson.php on line 31
What could the problem be?
The folder /Applications/XAMPP/xamppfiles/htdocs/test isn't writable by Apache - change the permissions so it can write to it. In Windows Explorer, right click the test folder, and untick "Read Only".
