sqlite_error_string
@minots: simplify what you are doing:
<?php
function sqlite_escape_array( &$arr ) {
$invalid = array( 'argv', 'argc' );
foreach ( $arr as $key => $val )
if ( ( strtoupper( $key ) != $key ) && !is_numeric( $key ) && !in_array( $key, $invalid ) ) {
if ( is_string( $val ) )
$arr[$key] = sqlite_escape_string( $val );
else if ( is_array( $val ) )
sqlite_escape_array( $arr[$key] );
}
return $arr;
}
?>
I'm not sure if the condition is equivalent to yours, but this excludes any numeric key, any completely uppercase'd keys and some selected (argc and argv) special keys. In case of never passing $GLOBALS or $_SERVER as argument one might shorten everything to this as a "pipelined" version:
<?php
function sqlite_escape_array( $arr ) {
foreach ( $arr as $key => $val )
if ( is_string( $val ) )
$arr[$key] = sqlite_escape_string( $val );
else if ( is_array( $val ) )
$arr[$key] = sqlite_escape_array( $val );
return $arr;
}
?>
PHP's syntax is more powerful than those of many other languages, even when it's supporting their one's as well.
sqlite_escape_string
(PHP 5, PECL sqlite >= 1.0.0)
sqlite_escape_string — Escapes a string for use as a query parameter
Opis
string sqlite_escape_string
( string $item
)
sqlite_escape_string() will correctly quote the string specified by item for use in an SQLite SQL statement. This includes doubling up single-quote characters (') and checking for binary-unsafe characters in the query string.
Although the encoding makes it safe to insert the data, it will render simple text comparisons and LIKE clauses in your queries unusable for the columns that contain the binary data. In practice, this shouldn't be a problem, as your schema should be such that you don't use such things on binary columns (in fact, it might be better to store binary data using other means, such as in files).
Parametry
- item
-
The string being quoted.
If the item contains a NUL character, or if it begins with a character whose ordinal value is 0x01, PHP will apply a binary encoding scheme so that you can safely store and retrieve binary data.
Zwracane wartości
Returns an escaped string for use in an SQLite SQL statement.
Notatki
Informacja: Do not use this function to encode the return values from UDF's created using sqlite_create_function() or sqlite_create_aggregate() - use sqlite_udf_encode_binary() instead.
Ostrzeżenie
addslashes() should NOT be used to quote your strings for SQLite queries; it will lead to strange results when retrieving your data.

sometimes i you have to escape an array instead of a string.
my function to do it works like:
array sqlite_escape_array ( &array string)
<?php
function sqlite_escape_array(&$arr)
{
while ( list($key, $val) = each($arr) ):
if ( (strtoupper($key)!=$key OR "".intval($key) == "$key") && $key!="argc" and $key!="argv"):
if (is_string($val)):
$arr[$key]=sqlite_escape_string($val);
endif;
if (is_array($val)):
$arr[$key]=sqlite_escape_array($val);
endif;
endif;
endwhile;
return $arr;
}
?>
