ereg: string to string

[Anon]

Hey

I want to check if any word in one string(words seperated by spaces) occurs anywhere in another string(format, name='value').
It is checking for valid id's in a string of name='value' pairs for a SQL query.

ereg("id_num_string",$data[$i]) works if there is one id. When there is more than one, I assume it is looking for "id1 id2" etc in order. Need it to do an 'OR' search throughout string. i.e. any whole word in string1 found anywhere in string2.

Thanks heaps!

i am not sure what you really mean, but to what i understand you are trying to look for a string named name='value' inside a string and replace them differently for each entry you find.

if thats correct, then you will need to have a while statement which loops untill no more entries are found (unique entries).

you could have while set on something like this:
while (ereg('string', 'replace_str', $arr_string))
.
.
// $arr_string[0] contains the current matched instance in the loop.
// so now you can use $arr_string[0] as your regex, for replacement.

$string = ereg($arr_string[0], 'replacce', 'string');
}

hope this idea helps.

thanks.

All i really needed was the OR operand which is '|' (which i just found out), so i just seperated the words in the regexp with the | and did the search on the second string.

Seems to work ok.
