New Comment:
I wish to change this bug report to a feature request. I frequently
need to check if a string begins or ends with another string. To check
if a string begins with another string, I often use strncmp():
ket% php -r 'var_dump(strncmp("HTTP_ACCEPT", "HTTP_", 5));'
int(0)
ket%
- but strncmp() is currently not able to check if a string ends with
another string:
ket% php -r 'var_dump(strncmp("foo_wrapper", "_wrapper", -8));'
Warning: Length must be greater than or equal to 0 in Command line code
on line 1
Call Stack:
0.0002 62840 1. {main}() Command line code:0
0.0002 62952 2. strncmp() Command line code:1
bool(false)
ket%
I wish strncmp() were able to check if a string ends with another
string.

This bug has been fixed in CVS.
Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.
Negative string length is not allowed in this function.
I just committed the patch, from now you'll get an error and FALSE in
this case.
