Remove Duplicate Text

[glenelkins]

Hi

Is there a function out there to search through a string and remove duplicates?

for example, if i had a string say "Hello World,Hello World,Hello World"

I only want it to contain 1 "Hello World"...how do you remove the rest?

Or say I had: "Hello World,I Hate The World,Hello World"  i only want 1 of each phrase

[code]Using your examples I am assuming that each phrase is separated by a comma. in that case this should work:

[code}<?php
<?
$str = " Hello World,I Hate The World,Hello World";
$strAry = split(",",$str);

foreach ($strAry as $strSearch) {
    $newStr .= (stripos($newStr, $strSearch)) ? "" : (($newStr)?",":"") . $strSearch;
}

echo $newStr; //Hello World,I Hate The World
?>

?>[/code]
