[SOLVED] Finding keywords from text

[chantown]

Hi,

 

Let's say I have an array of words

 

0=>"hello"

1=>"php"

2=>"bad"

3=>"programming"

 

 

And then I have a string of text (from a textarea or something)

 

------hello, Programming is very fun i love c++ and it's great language.------

 

Is there any special function I can use to "scan" this text and see if there are the keywords in this array, and if so, store them in an array?

 

For example, in this case, "hello" and "programming" would be the result after the "scan"

Assuming you have a textarea named texts you can try like this

<?php

if (isset($_POST['submit'])) // when user press submit btn
{

$arr = array(0 => "hello", 1 => "php", 2 => "bad" , 3 => "programming"); //your array of texts 

$string = $_POST['texts']; // get value from text box 
$string = split (" ", $string);

foreach ($string as $v) 
{
   	//echo "Current value of \$string: $v.\n";
   
   	if (in_array($v, $arr)) 
{
    echo "Got $v <br />";
}
   
}

}

?>
