limiting field view to X words - problem with loop

[phpnewbie]

Hi there,

I have function which takes text from mysql and displays limited number of words with [more]. It also search for nearest space to avoid breaking the word in a middle.
It was compiled from 2 other func. so I have a little problem with infinite loop in while statement..

function is:

function Cut($article_desc,$url) {
return CutConvert($article_desc).'...' . '[<a href="'.$url.'">more</a>]';
}

function CutConvert($str, $index=30, $char=" ") {
while (substr($str, $index, 1)!=$char) $index++;
return substr($str, 0, $index);
}



How to fix potential infinite loop in 'while'?
In the code above if the last character in the $str is
not blank, it will loop forever because the substr() will return an empty string "" and "" <> " ", so it loops forever...


pls help

You can actually do this in your query:

SELECT SUBSTRING_INDEX(field, ' ', 30) as shortext from table;

..becouse query is generated by CodeCharge software, and code I need have to be included manually as 'global' funcion, then recalled in specific page.

So I can put parameter (number of chars) in 2 places only:
- at function definition
- at recall function (with specific db field) on php page.

Why can't you just edit the code created by CodeCharge, or possibly code it yourself?
