[SOLVED] PHP Search Text Function

[ipwnzphp]

I need a function in php where i can search the text then do if statements based off the keywords. The code below states that if it finds joomla then its correct. but lets say i need to find web design also. if both are there it needs to say we fount both if only 1 is there it needs to say we fount only 1

 

$search_for = "joomla";
$the_items_description = "i need some joomla and web design work done";

function textsearch($the_items_description) {
global $search_for;
$pos = strpos($the_items_description, $search_for);
if ($pos === false) {
return false;
} else {
return true;
}
}


if (textsearch($the_items_description) == true) {
echo "correct";
} else {
echo "incorrect";
}

<?php
$searchWords=array("joomla", "web design");
$string="i need some joomla and web design work done";
$wordResults=0;
$totalWords=count($searchWords);

function searchForWord($string, $search)
  {
$search="/{$search}/i";
  if (preg_match($search, $string))
   {
   return 1;
   }
  return 0;
  }

foreach ($searchWords as $search)
  {
  $wordResults+=searchForWord($string, $search);
  }
echo "Found {$wordResults} of {$totalWords}";
?>

Thanks works prefect!

That's a little much. Also, preg_match is not very efficient for this:

 

<?php

function textsearch($desriptionStr, $searchAry)
{
    $matchCount = 0;
    foreach ($searchAry as $searchStr)
    {
        $matchCount += (strpos($desriptionStr, $searchStr)!=false);
    }
    return $matchCount;
}

$search_for = array('joomla', 'web design');
$the_items_description = "i need some joomla and web design work done";

echo "There are " . textsearch($the_items_description, $search_for) . " matches";

?>

Next question what if i wanted to add if statements to it like

 

if ($searchStr == "joomla") {
$site = f_open("http://www.google.com");
}

That depends. Without knowing how this is to be implemented I don't know how best to build a solution. It could be included in the function or not. here is one solution:

 

<?php

function textsearch($desriptionStr, $searchAry)
{
    $matchAry = array();
    foreach ($searchAry as $searchStr)
    {
        $matchAry[] = $searchStr;
    }
    return $matchCount;
}

$search_strings = array('joomla', 'web design');
$description = "i need some joomla and web design work done";
$matches = textsearch($description, $search_strings);

echo "There are " . count($matches) . " matches";

if (in_array('joomla', $matches)) {
    $site = f_open("http://www.google.com");
}

if (in_array('web design', $matches)) {
    //Do something else
}

?>

There are 0 matches

the code below is showing fount asp even though asp is not in the $description var. How do i fix this?

 

function textsearch($desriptionStr, $searchAry) {
$matchAry = array();
foreach ($searchAry as $searchStr) {
$matchAry[] = $searchStr;
}
return $matchAry;
}

$search_strings = array('joomla', 'web design', 'asp');
$description = "i need some joomla and web design work done";
$matches = textsearch($description, $search_strings);

echo "There are " . count($matches) . " matches";

if (in_array('joomla', $matches)) {
echo "<br><br>Fount Joomla<br><br>";
}

if (in_array('web design', $matches)) {
echo "Fount Web Design<br><br>";
}

if (in_array('asp', $matches)) {
echo "Fount ASP";
}

I beg to differ the fault of using preg_match. Using preg_match will allow for wild cards and advanced searching.

I got it fixed now i think and here was what i came up with to use.

 

<?

$Desc = "$_POST[desc]";

// Joomla
function find_joomla($Desc) {
$keyword = "joomla";
$find = strpos($Desc, $keyword);
if ($find == true) {
echo $keyword . "Found";
}
}

echo find_joomla($Desc);

// ASP
function find_asp($Desc) {
$keyword = "asp";
$find = strstr($Desc, $keyword);
if ($find == true) {
echo $keyword . "Found";
}
}

echo find_asp($Desc);
?>

If the OP stated he needed to search using wilecards or regular expressions then, by all means, preg_match() woud be the way to go. But his request didn't mention any such thing and the manual for preg_match() clearly states:

 

Do not use preg_match() if you only want to check if one string is contained in another string. Use strpos() or strstr() instead as they will be faster.
