Summary: zend_parse_parameters: error when signature is
s|ssbs
Status: Not a bug
Type: Bug
Package: Unknown/Other Function
Operating System: Ubuntu 12.04 LTS 32 bits
PHP Version: 5.3.10
Block user comment: N
Private report: N
New Comment:
s|ssbs means the functions takes a string as the required first argument and
string string bool string as optional arguments. The | just delimits required
arguments from optional arguments. zend_parse_parameters does not specify the
return value type (actually the return value type isn't specified anywhere, you
just return it.)

sorry, I checked many times that I was not missing something and I don't
understand your statement. can you please clarify? I am passing ssbs. my
understanding is that s|ssbs means the function takes ssbs as arguments and
returs
s.

You are specifying "s|ssbs", but it's passing args for "s|sbs".

Description:
------------
zend_parse_parameters is having trouble parsing this signature: s|ssbs; the
error happens with the last "bs" arguments. the signature "ssbs" works well.

Test script:
---------------
PHP_FUNCTION(test_parse_parameters) {
char *p_str1 = "";
int p_str1_len;
char *p_str2 = "";
int p_str2_len;
char *p_str3 = "";
int p_str3_len;
zend_bool b = 0;
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s|ssbs", &p_str1,
&p_str1_len, &p_str2,
&p_str2_len, &b, &p_str3, &p_str3_len) == FAILURE) {
return;
}
zend_error(E_WARNING, "First parameter: len[%d] value[%s]", p_str1_len,

char returnValue[256];
char* result;
sprintf(returnValue, "%d#%s", 0, "houston, we have a problem!");
result = estrdup(returnValue);
