Without the aid of the escape mechanism, how to put a raw string into a variable?
Hi guys and gals...
I have been racking my brains with this one and I can't find anything about it...
Consider the code and the results below:
Results on OSX 10.14.x:
As you can see saving a rawstring to disk and retrieving it again works but trying to force a rawstring without the escape mechanism fails catastrophically.
This is one of the USEFUL uses of 'cat' as it works admirably in this case but it requires I/O to do so...
I need to avoid the use of the escape mechanism inside the failing condition in case I want to __edit__ said rawstring inside any code.
I would like to know what is different about putting a rawstring into a variable using 'cat' and attempting to do so using hard coding.

CUBRID_REAL_ESCAPE_STRING(3) 1 CUBRID_REAL_ESCAPE_STRING(3)cubrid_real_escape_string - Escape special characters in a string for use in an SQL statementSYNOPSIS
string cubrid_real_escape_string (string $unescaped_string, [resource $conn_identifier])
DESCRIPTION
This function returns the escaped string version of the given string. It will escape the following characters: '. In general, single quo-
tations are used to enclose character string. Double quotations may be used as well depending on the value of ansi_quotes, which is a
parameter related to SQL statement. If the ansi_quotes value is set to no, character string enclosed by double quotations is handled as
character string, not as an identifier. The default value is yes. If you want to include a single quote as part of a character string,
enter two single quotes in a row.
PARAMETERS
o $unescaped_string
-The string that is to be escaped.
o $conn_identifier
- The CUBRID connection. If the connection identifier is not specified, the last connection opened by cubrid_connect(3) is
assumed.
RETURN VALUES
Escaped string version of the given string, on success.
FALSE on failure.
EXAMPLES
Example #1
cubrid_real_escape_string(3) example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$unescaped_str = ' !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^_`abcdefghijklmnopqrstuvwxyz{|}~';
$escaped_str = cubrid_real_escape_string($unescaped_str);
$len = strlen($unescaped_str);
@cubrid_execute($conn, "DROP TABLE cubrid_test");
cubrid_execute($conn, "CREATE TABLE cubrid_test (t char($len))");
cubrid_execute($conn, "INSERT INTO cubrid_test (t) VALUES('$escaped_str')");
$req = cubrid_execute($conn, "SELECT * FROM cubrid_test");
$row = cubrid_fetch_assoc($req);
var_dump($row);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>
The above example will output:
array(1) {
["t"]=>
string(95) " !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^_`abcdefghijklmnopqrstuvwxyz{|}~"
