you need to escape your characters:

$pattern = '/([{|}|\[|\]|\'|\"])/gi';
$replacement = '\${1}';
echo preg_replace($pattern, $replacement, $string);

This didn't work for me. The 'g' at the end of the pattern causes preg_replace to return nothing, and it's not actually needed because preg_replace already replaces all occurrences of the pattern. Also, the replacement should be '\\\\${1}', which inserts a single backslash in front of the character found in the pattern.
