String replace

[dodg]

Now Im sure this is really easy, but for some reason its testing me and then moved onto the annoying stage, so in comes help from the forums 🙂

All I want to do is go through a string a replace all oocurences of (y) with (n)

The data im getting is from a db. Heres my snippet of code ..

for($i=0; $i<mysql_num_rows($result); $i++)
{
$row = mysql_fetch_row($result);
$rowtext = $row[1];
ereg_replace("(y)", "(n)", $rowtext);

           //then replace in db

}

But its not replacing the (y) with a (n). I think its somethign to do with the use of brackets. But anyway any help appreciated 🙂

Thanks
Nick

Hi Nick,

In regular expressions, parenthesis is used to group parts of the expression together. If you want to search on '(' or ')' (and other characters) you need to escape them ...

ereg_replace("(y)", "(n)", $rowtext);

... don't need to do it in the replacement expression.

Simpler to use str_replace ...

str_replace("(y)", "(n)", $rowtext);

Paul. 🙂

Yeah thanks

Oh and also I might want to actually assign the function to something 🙂

i.e I didnt say $rowtext = ....

I just did the function for no reason 🙂
