thank's
cannot see the wood for the trees

know it works but with 

buf = php_str_to_str(value, value_len, "'", 1, "\\x27", 4);
i get a segfault

buf = php_str_to_str(value, value_len, "'", 1, "\\x2", 3);
works but not as i like

i want to build a js escape function 
<script type='javascript'></script> should become 
<script type=\x27javascript\x27></script>

an so on
