text replacer

[raisinlove]

Hi, I'm not quite sure how else to call this but here is the situation:

I currently use a template file made up of html and a PHP include expression to generate the content. So far, no problem.

Now I would like to add another function that will detect a specific string of text in the content and replace it with another text. In other words, I would like for my script to detect a certain word in included content and replace it with another word (in my case a URL.)

So is there some kind of search and replace function I could use for this? If this isn't clear, feel free to email me directly and I'll supply more info.

Thank you!

ereg_replace -- Replace regular expression

str_replace -- Replace all occurrences of the search string with the replacement string (easiest way)

Hope this helps!!

I knocked this function up which would search through a string and replace words found in the string which exist in a MySQL table.

<?php

function ConvertToGlossaryText($ConvertThis) {

// Get all the glossary terms from the glossary table an store them
// in an array

$GlossaryTerms = array();

$SQLQuery = "SELECT glossary_term_id, term FROM glossary_term_tbl ORDER BY glossary_term_id ASC;";
$Result = mysql_query($SQLQuery);

while ($GlossaryTerms[] = mysql_fetch_array($Result)) {

}
mysql_free_result($Result);

// Replace any word found in the article which exists in the glossary
// array with a reference to the glossary php page

for ($intWords=0; $intWords < count($GlossaryTerms) -1; $intWords++){
    $GlossaryID = $GlossaryTerms[$intWords] [0];
    $FindThis = $GlossaryTerms[$intWords] [1];

    $ReplaceWith = "<A HREF=\"glossary.php?id=$GlossaryID\">$FindThis</A>";
    $ConvertThis = eregi_replace ($FindThis, $ReplaceWith, $ConvertThis);
}

return $ConvertThis;

}

Good Luck
