Hi,

ok im having some real trouble here..
im trying to load acronyms and thier definitions from a string like this:

$string = 'HTML[+]HyperText Markup Language[-]  

                PHP[+]PHP hypertext preprocessor[-]  

                XML[+]Extensible Markup language[-]  

                CSS[+]Cascading Sylesheets[-] ';

then i want to put them into an associative array and then use str_replace();
to search a string like this:

$string_read = 'this a string it may contain acronyms such as PHP, HTML,XML or even CSS... ';

for acronyms (ie: CSS) and replace them with the correct acronym tag (ie: <acronym title="Cascading Stylesheets">CSS</acronym>

this is the way im tryin to do this...

<?
$string = 'this is a string that contains acronyms like PHP, HTML and CSS';
$nice_string = 'HTML[+]HyperText Markup Language[-]  

                PHP[+]PHP hypertext preprocessor[-]  

                CSS[+]Cascading Sylesheets[-] ';  

$str_buff = explode('[-]',trim($nice_string)); 

$acronyms = array();   

foreach ($str_buff as $buff) {
  list($temp1, $temp2) = explode('[+]', $buff);
  $acronyms[$temp1]= '<acronym title="'.$temp2.'">'.$temp1.'</acronym>';
}

echo str_replace(array_keys($acronyms), $acronyms, $string);
?> 

but it only seems to do it to 1 of the acronyms this is the output..

this is a string that contains accronyms like PHP, <acronym title="HyperText Markup Language">HTML</acronym> and CSS

can sum1 please help me?

You're not splitting up your string in a way that matches the way it's been built.

What comes after the first "[-]" is not PHP, it's more like "space, space, space, carriage return, linefeed, space, space, space, PHP". That sequence doesn't appear in your string so it's never substituted.

You could do two things:

1. tie down the string definition, so that you remove the whitespaces:

 $string = 'HTML[+]HyperText Markup Language[-]PHP[+]PHP hypertext preprocessor[-]XML[+]Extensible Markup language[-]CSS[+]Cascading Sylesheets[-]';  

2. leave the string definition alone and trim the whitespace from each substring:

list($temp1, $temp2) = explode('[+]', trim($buff));
