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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
