String find values?

[Anon]

Hi, I would like to know if there is a function in php where it returns the value of a character in a string, i.e in c/c++ has
string.find() and it returns the value.. any ideas?

Thanks,
Zak Thompson

If you want the ascii value of a single character then you can use the ord/chr string function pair to go back and forth from ascii (EBCIDIC maybe? ??) values to characters and back.

print ord("a");

will print the number 97, while

print chr(97);

will print an a.

since you can use array syntax to grab a piece of a string, you can get the ascii value of a char in a particular position by doing this:

$a="abcdef";
print ord($a[2]);

will print 99, the ascii value of "c".
print ord($string[5]);

i need something like.. if

$temp = "abcd";

and i want to get a int value for d, and in c/c++ i could do $dvalue = temp.find("d"); and $dtemp == 4 and then i could just use substr and do how ever i please. it can be done using ereg() but there has to be a simpler way.

thanks
