PHP mysqli: ssl_set() function
mysqli_ssl_set() function / mysqli::ssl_set
The mysqli_ssl_set() function / mysqli::ssl_set is used to establish secure connections using SSL. However, this function does nothing unless OpenSSL support is enabled.
Note: This function must be called before mysqli_real_connect().
Note: MySQL Native Driver does not support SSL before PHP 5.3.3. MySQL Native Driver is enabled by default on Microsoft Windows from PHP 5.3+.
Syntax:
Object oriented style
bool mysqli::ssl_set ( string $key , string $cert , string $ca , string $capath , string $cipher )
Procedural style
bool mysqli_ssl_set ( mysqli $link , string $key , string $cert , string $ca , string $capath , string $cipher )
Parameter:
Name | Description | Required/Optional | |
---|---|---|---|
link | A link identifier returned by mysqli_connect() or mysqli_init() | Required for procedural style only and Optional for Object oriented style | |
key | The path name to the key file. | Required | |
cert | The path name to the certificate file. | Required | |
ca | The path name to the certificate authority file. | Required | |
capath | The pathname to a directory that contains trusted SSL CA certificates in PEM format. | Required | |
cipher | A list of allowable ciphers to use for SSL encryption. | Required | |
Any unused SSL parameters may be given as NULL. |
Usage: Procedural style
mysqli_ssl_set(connection,key,cert,ca,capath,cipher);
Parameter:
Name | Description | Required/Optional |
---|---|---|
connection | Specifies the MySQL connection to use | Required. |
key | Specifies the path name to the key file | Required |
cert | Specifies the path name to the certificate file | Required |
ca | Specifies the path name to the certificate authority file | Required |
capath | Specifies the pathname to a directory that contains trusted SSL CA certificates in PEM format | Required |
cipher | Specifies a list of allowable ciphers to use for SSL encryption | Required |
Return value:
This function always returns TRUE value. If SSL setup is incorrect mysqli_real_connect() will return an error when you attempt to connect.
Version: PHP 5, PHP 7
Example of object oriented style:
Example:
<?php
$con=mysqli_connect("localhost","user1","datasoft123","hr");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$con=mysqli_init();
if (!$con)
{
die("mysqli_init failed");
}
mysqli_ssl_set($con,"key.pem","cert.pem","cacert.pem",NULL,NULL);
if (!mysqli_real_connect($con,"localhost","user1","datasoft123","hr"))
{
die("Connect Error: " . mysqli_connect_error());
}
// Some queries...

PHP: Tips of the Day
var_export(): var_export() dumps a PHP parseable representation of the item.
You can pass true as the second parameter to return the contents into a variable.
Example:
<?php $myarray = [ "PHP", "Tips" ]; $mystring = "PHP Tips"; $myint = 28; var_export($myarray); var_export($mystring); var_export($myint); ?>
Output:
array ( 0 => 'PHP', 1 => 'Tips', )'PHP Tips'28
To put the content into a variable, you can do this:
$array_export = var_export($myarray, true); $string_export = var_export($mystring, true); $int_export = var_export($myint, 1); // any `Truthy` value
After that, you can output it like this:
printf('$myarray = %s; %s', $array_export, PHP_EOL); printf('$mystring = %s; %s', $string_export, PHP_EOL); printf('$myint = %s; %s', $int_export, PHP_EOL);
Example:
<?php $myarray = [ "PHP", "Tips" ]; $mystring = "PHP Tips"; $myint = 28; $array_export = var_export($myarray, true); $string_export = var_export($mystring, true); $int_export = var_export($myint, 1); printf('$myarray = %s; %s', $array_export, PHP_EOL); printf('$mystring = %s; %s', $string_export, PHP_EOL); printf('$myint = %s; %s', $int_export, PHP_EOL); ?>
This will produce the following output:
Output:
$myarray = array ( 0 => 'PHP', 1 => 'Tips', ); $mystring = 'PHP Tips'; $myint = 28;
