Hello all,

I need to find position of the last "/" in a string. strpos is not accepting "/" as an input. Kindly guide me how am i gona do this.

Thanks

also, i need to escape special characters. i am using strpos and want to match the pattern ?q=, but it wont accept the ? character. I think it's a special character so kindly tell me how can i escape it.

 

Thanks

There must be something wrong with your script, strpos() certainly accepts / as a needle.

 

if ($pos = strpos('path/to/directory', '/')) {
    print 'at: '. $pos;
} else {
    print 'no pos';
}

 

prints "at: 4"

strpos() has no special characters:

if ($pos = strpos('path/to/directory?q=hello+world', '?')) {
    print 'at: '. $pos;
} else {
    print 'no pos';
}

 

prints "at: 17"

sounds more like you are using a preg_xxx or ereg_xxx function and are using / as the delimiter for the pattern (and not escaping the / in your pattern) which also explains that whole business with the question mark. 

 

In general, you would escape something by putting a \ before it.  But if you want specific help, post some code.
