Question

I am migrating my website from mysql_* methods to mysqli.

When I was using mysql a data like this:

$variable = <<<eot
    "asdasd" hello 'name name'
    // 
    \\
    "end"   
eot;

Was inserted in Database like follows:

 "asdasd" hello 'name name'
    // 
   \
    "end" 

And it was very OK.

Now it inserts the same data like following:

\"asdasd\" hello \'name name\'\r\n  // \r\n \\\r\n  \"end\"  

Can anyone please tell me how to maintain old way of inserting things into db. I do not need \ and \r and \n and such things I guess. Thanks

Answer 1

I can see no difference.

Table definition:

create table test (s text)

PHP test source:

<?php 
$variable = <<<eot
    "asdasd" hello 'name name'
    // 
    \\
    "end"   
eot;

// mysql version
$conn = mysql_connect('localhost', 'USERNAME', 'PASSWORD');
mysql_select_db('test', $conn);
$sql = "insert into test values ('" . mysql_escape_string($variable) . "')";
$result = mysql_query($sql, $conn);

// mysqli version
$conn = mysqli_connect('localhost', 'USERNAME', 'PASSWORD', 'test');
$sql = "insert into test values ('" . mysql_escape_string($variable) . "')";
$result = mysqli_query($conn, $sql);

// mysqli version (prepared statement)
$conn = new mysqli('localhost', 'USERNAME', 'PASSWORD', 'test');
$sql = 'insert into test values (?)';
$sth = $conn->prepare($sql);
$sth->bind_param('s', $variable);
$result = $sth->execute();

Every version produces the same entry in the table. So, either this is just a different output you have or your code does something different.
