String Replacement Question

[wiseguy]

I know very little about php and I'm limited to the basic altering of scripts. I have a script that replaces characters in urls. It stores information in a php file as opposed to a database. Basically it takes a url like http://www.somesite.com and creates a link from it using the url as the link text. What I would like to do is change the function as to where I can create the links with my own link text. Below are the functions used by the script.

$str = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',    '<a href="\\1" target="_blank">\\1</a>', $str);
$str = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)',    '\\1<a href="http://\\2" target="_blank">\\2</a>', $str);

I assume your source file only has the url? Where will the text come from?

Thanks for the response.

This is a Q&A script. The source file contains everything including the question text, answer text, and urls. When reading a url from the source the script writes out the link (taken from an entered url) in the form of:
[code]<a href="http://www.somesite.com">http://www.somesite.com</a>[/code]

I want to be able to specify my own link text as in:
[code]<a href="http://www.somesite.com">My Text Here</a>[/code]

Change the \\1 at the end: [tt]<a href="\\1" target="_blank">[b]\\1[/b][/tt]

That will remove the url as the link text but does not allow me to add my own link text.

And the text you want to specify, is in the source too? give us a sample of your code so we can help you build a matching pattern.

The data is stored in a text file. The script takes whatever you enter as a url and automatically makes that url the link text so you end up with a link like below on a dynamically created page:
[code]<a href="http://www.somesite.com">http://www.somesite.com</a>[/code]

This is the scripts link function:
[code]function convertLinks($str) {
$str = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',    '<a href="\\1" target="_blank">\\1</a>', $str);
$str = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)',    '\\1<a href="http://\\2" target="_blank">\\2</a>', $str);
$str = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})',    '<a href="mailto:\\1">\\1</a>', $str);
return $str;[/code]

This is an example block from the text file database.
[code]7\¦I have MP3 files of songs I have written, and I would like to convert them to MP3+G format.  How do I create the .CDG file to go with the .MP3 file?  Is there free software to do this?\¦There are several software applications that will allow you to do this. I do not know of any free ones. To find find some of these programs go to http://www.karaoke-software.net/cdg-authoring.html\¦205.167.198.122\¦1155245666\¦1157770737[/code]

I would just like to be able to code a link in my responses without the script rewriting my input.
