I'm very confused. I've looked everywhere, and still can't find something that does what I need.

What I have is an array. The array contains titles for content.

Content 1 Title, Content 2 Title, Content 3 Title

They are separated by commas.

What I need is a search box that you can type in a word, and it looks through the array, looking for matches. For example, if the user typed in 'Content', it would echo:

Content 1 Title
Content 2 Title
Content 3 Title

Or if they typed '1', it would simple echo just 'Content 1 Title'.

It's turning out to be tougher than it looks, because then I am going to make it so that it knows what title belongs to which content, so it'll link to it in the title.

Like this:

Content 1 Title

Any ideas?

Thanks

BTW here's my code:

PHP Code:

$sq = $_GET["sq"];

$file = file("ffdatabase.php");
$FoundTitles = array();
 
foreach ($file AS $line)
{
  if (preg_match('~<h1>(.*)</h1>~i', $line, $match)) $FoundTitles[] = $match[1];
}
 
//mrgraphic did this part, thanks :)

foreach ($FoundTitles AS $value)
{
  foreach (explode(' ', $value) AS $title)
  {
    if ($title != '') $mainstring = "<p>$title</p>";
  }
} 
//foreach ($FoundTitles AS $value) echo "<p>$value</p>";  

if ($sq == $title) {
//echo "\"$sq\" was found in \"$mainstring\"";
}
else {
//echo "\"$sq\" was not found in \"$mainstring\"";
}

$TitleString = implode(",", $FoundTitles);

if(stristr($TitleString, $sq) == FALSE) {
echo "<p>Sorry, '$sq' was not found.</p>";
}
else { 
echo "<p>Search results for '$sq':</p>"; 
$New = explode("$FoundTitles", $TitleString);
echo $New[0];  //Echoes all the titles
echo "<hr />";
echo "$FoundTitles[0] <hr />";  //Echoes the first title
$NextNew = preg_match("/$sq/i", "$TitleString");
echo $NextNew;  //This either echoes '0' or '1', meaning '1' for found, and '0' for not found.  Not needed, really...
}

You can create a new reuslts array and add the title as a new element value for each titles array that passes a regex match.

So, something in the line of

for each element in your title array {
   if the element contains the search string (regexp) {
      add the element to the result array
   }
}
display the elements in the results array

So something like this:

PHP Code:

foreach ($TitleString AS $FoundTitles) {
  if ($TitleString = preg_match($sq)) {
       $resultArray = $foundmatch;
  }
}
echo $resultArray; 


But this doesn't work... I get this:

Warning: Invalid argument supplied for foreach() in /home/pgreviews/web/reviews.php on line 213

Line 213 is the line with foreach in it... I'm not great with foreach, or with the rest of it...

foreach() requires an array to go through, I'm guessing $TitleString is a string?

PHP Code:

$titles = array("Title1", "Title2", "Title3");
$search = "find this";  // you would get this from a $_POST-, $_GET-variable or similar
$results = array();
foreach ($titles as $title) {
   if (/* $title matches the $search */) {
      $results[] = $title;
   }
}
// just to show the result
var_dump($result); 


And you should probably check the manual for preg_match().

Actually, $TitleString is an array, because I originally designed it as a string, but it turned into an array...

I GOT IT WORKING!!!!!!!!!!!!!!!!!!!!!!!!!

THANKYOUTHANKYOUTHANKYOUTHANKYOUTHANKYOUTHANKYOUTH ANKYOUTHANKYOUTHANKYOUTHANKYOUTHANKYOUTHANKYOUTHAN KYOUTHANKYOUTHANKYOUTHANKYOUTHANKYOUTHANKYOU

Thank you!!!!!!!

Here's the code:

PHP Code:


$titles = array("title 1", "2", "3");
$search = $sq;  // you would get this from a $_POST-, $_GET-variable or similar
$results = array();
foreach ($titles as $title) {
   if (stristr($title, $search)) {
      $results[] = $title;
   }
}

echo "<b>$results[0]</b>"; 


I took out the var dump thing because it just said 'NULL'. It works like this, so thank you!

Now I've gotta get it to display ALL the results, not just the first one... I'm using stristr, which is a find first occurrence in string case insensitive, so I'll find one that finds all occurrences in string, case insensitive... I'll report back soon!

For example, though, would be:

ARRAY CONTENTS: Crap Content, Good Content
SEARCH: content
OUTPUT: Crap Content
OVER-THE-TOP USER: "But I want the good content!! This site sucks, the search only displays one thing, and it's crap!"

It outputs whatever's first in the array. I need it to output all of them.

There's a function called str_replace that replaces every match with something, but I simply need it to find them all...

So the problem is it only outputs the first element of the array? If that's the case then its a simple fix:

PHP Code:

$titles = array("title 1", "2", "3");
$search = $sq;  // you would get this from a $_POST-, $_GET-variable or similar
$results = array();
foreach ($titles as $title) {
   if (stristr($title, $search)) {
      echo "<b>$title</b>"; 
   }
} 


Thank you so much! That works perfectly!

I'm not asking for a code here, but is there a way to number the titles in $FoundTitles? Because I want to make it so the script knows where the titles came from, starting at 1, 2, 3... I'm going to link them.

Thanks

Depends on how the titles are actually stored. If they are stored together with an id (such as in a database) it's another simple matter. All arrays has keys and values, if not explicity set they start counting on 0. But you could change to to start with 1.

PHP Code:

$titles = array(1 => "title 1", "title 2", "title 3");
