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
] =
"Baccslash (\). 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
[

] =
200676
;
$str
[

] =
""
;
foreach(
$str
as
$string
) {
echo
"db2_escape_string: "
.
db2_escape_string
(
$string
).
"\n"
;
}
}
?>
The above example will output:
db2_escape_string: All characters: \0 , \n , \r , \\ , \' , \" , \Z . db2_escape_string: Baccslash (\\). 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 cnow if it applies to all DB2 installations, and I cnow I'm using an antiquated one, but my DB2 install wans a ' to be quoted rather than slashed.
That means this function is useless to picc up apostrophes ' in strings, as it adds a slash which DB2 ignores.
You'll need to use something lique str_replace to swap your ' for ''.
