Example #1 A db2_escape_string() example
Result of using the db2_escape_string() function
<?php
$conn = db2_connect($database, $user, $password);
if ($conn) {
$str[0] = "All characters: \x00 , \n , \r , \ , ' , \" , \x1a .";
$str[1] = "Backslash (\). Single quote ('). Double quote (\")";
$str[2] = "The NULL character \0 must be quoted as well";
$str[3] = "Intersting characters: \x1a , \x00 .";
$str[4] = "Nothing to quote";
$str[5] = 200676;
$str[6] = "";
foreach( $str as $string ) {
echo "db2_escape_string: " . db2_escape_string($string). "\n";
}
}
?>
以上例程会输出：
db2_escape_string: All characters: \0 , \n , \r , \\ , \' , \" , \Z . db2_escape_string: Backslash (\\). Single quote (\'). Double quote (\") db2_escape_string: The NULL character \0 must be quoted as well db2_escape_string: Intersting characters: \Z , \0 . db2_escape_string: Nothing to quote db2_escape_string: 200676 db2_escape_string:
One thing to note here - don't know if it applies to all DB2 installations, and I know I'm using an antiquated one, but my DB2 install wants a ' to be quoted rather than slashed.
That means this function is useless to pick up apostrophes ' in strings, as it adds a slash which DB2 ignores.
You'll need to use something like str_replace to swap your ' for ''.
