mysqli_real_escape_string
MYSQLI_REAL_ESCAPE_STRING(3) 1 MYSQLI_REAL_ESCAPE_STRING(3)mysqli::real_escape_string - Escapes special characters in a string for use in an SQL statement, taking into account the current charset of the
connection
Object oriented style
SYNOPSIS
string mysqli::escape_string (string $escapestr)
DESCRIPTION
string mysqli::real_escape_string (string $escapestr)
Procedural style
string mysqli_real_escape_string (mysqli $link, string $escapestr)
This function is used to create a legal SQL string that you can use in an SQL statement. The given string is encoded to an escaped SQL
string, taking into account the current character set of the connection.
Caution
Security: the default character set
The character set must be set either at the server level, or with the API function mysqli_set_charset(3) for it to affect
mysqli_real_escape_string(3). See the concepts section on character sets for more information.
PARAMETERS
o $
link -Procedural style only: A link identifier returned by mysqli_connect(3) or mysqli_init(3)
o $escapestr
- The string to be escaped. Characters encoded are NUL (ASCII 0),
,
, , ', ", and Control-Z.
RETURN VALUES
Returns an escaped string.
EXAMPLES
Example #1
mysqli::real_escape_string example
Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$mysqli->query("CREATE TEMPORARY TABLE myCity LIKE City");
$city = "'s Hertogenbosch";
/* this query will fail, cause we didn't escape $city */
if (!$mysqli->query("INSERT into myCity (Name) VALUES ('$city')")) {
printf("Error: %s
", $mysqli->sqlstate);
}
$city = $mysqli->real_escape_string($city);
/* this query with escaped $city will work */
if ($mysqli->query("INSERT into myCity (Name) VALUES ('$city')")) {
printf("%d Row inserted.
", $mysqli->affected_rows);
}
$mysqli->close();
?>
Procedural style
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City");
$city = "'s Hertogenbosch";
/* this query will fail, cause we didn't escape $city */
if (!mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
printf("Error: %s
", mysqli_sqlstate($link));
}
$city = mysqli_real_escape_string($link, $city);
/* this query with escaped $city will work */
if (mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
printf("%d Row inserted.
", mysqli_affected_rows($link));
}
mysqli_close($link);
?>
The above examples will output:
Error: 42000
1 Row inserted.
NOTES
Note
For those accustomed to using mysql_real_escape_string(3), note that the arguments of mysqli_real_escape_string(3) differ from what
mysql_real_escape_string(3) expects. The $link identifier comes first in mysqli_real_escape_string(3), whereas the string to be
escaped comes first in mysql_real_escape_string(3).
SEE ALSO mysqli_set_charset(3), mysqli_character_set_name(3).
