Why am I getting three arrays ?
--- code ---
<?php
$string[] = "Hello hello server site search me and highlight my words in
search array words";
$string[] = "Hello hello this is the second array elemaent to test server";
$string[] = "this IS the third element of an array for words testing";
$string2 = "Hello hello server site search me and highlight my words in
search array words";
$search = "hello search";
//$string = trim($string);
$search = trim($search);
function searchlines(){
global $search;
global $string;
$words = explode(' ',$search);
$words = array_unique($words);
for($i=0; $i<=count($string); $i++){
$word = preg_replace("/#/","\#",$words[$i]);
$pregmatch = "#($word)(?![^<]*>)#i";
$pregreplace = "<b>$1</b>";
$h_string = preg_replace($pregmatch,$pregreplace,$string);
$string = $h_string;
}
echo $string;
}
array_walk($string, 'searchlines');
//echo "Clean: $string2<br />";
//echo "Criteria: $search<br />";
//echo "HighLighted: $h_string<br />";
?>
My output is 3 x the expected output. Why ?
Any help is appreciated
