[SOLVED] match words wont match why.

[redarrow]

 

match words wont match why?

<?php

$x="see you soon redarrow";

$word=array("a","see","c");

foreach($word as $bad_word){

if($bad_word==$x){

echo"You entred a bad word!";
exit;	

}else{

echo "Word is good!";	
exit;
}
}
?>

??? wouldn't you have to check the $x string using some strstr or similar function?

[pocobueno1388]

<?php

$x="see you soon redarrow";
$words=array("a","see","c");
$word = explode(" ", $x);

   for($i = 0; $i < count($word); $i++){

      if (in_array($word[$i], $words)){
         echo "$word[$i] - Bad word!<br>";
      } else {
         echo "$word[$i] - Good Word!<br>";
      }

   }
?>

 

EDIT:

It was because you were trying to match words to your whole string of words. You had to split up your string then check against every individual word...

can u kindly post a proper example to cheek if a word exist in a

message please the below last posted example driven me mad cheers.

 

there must ba a simple way to see if a bad word exists in a set condition.

<?php


$message="your all  s and all have  you ";

$bad_words=array("c","b","s");

$x=explode(" ",$message);

for($i=0; $i<count($x); $i++){

$t=in_array($x[$i], $bad_words);

if($t==true){
	echo "bad word";
	}else{
	echo "good word";


}
}

?>

[redarrow]

example the loop wont work

 

<?php

$x="you soon  see redarrow";

$word=array("a","see","c");

$message=explode(" ",$x);

for($i=0; $i < count ($message); $i++){

if(in_array($message[$i], $word)){

echo"You entred a bad word!";
exit;	

}else{

echo "Word is good!";	
exit;
}
}
?>

[suma237]

<?

$x=" you soon redarrow";

$word=array("a","see","c");

 

$message=explode(" ",$x);

 

for($i=0; $i < count ($message); $i++){

 

if(in_array($message[$i], $word)){

 

echo"You entred a bad word!";

exit;

 

}else{

 

echo "Word is good!";

echo"You entred a bad word!";


}else{

echo "Word is good!";	

}

try

<?php
function bad_word($string, $array_of_bad_words, $bad_words_find = array()) {
$out = true;
$bad_words_find = array();
$bad_words_find = array_intersect(explode(' ',$string),$array_of_bad_words);
if (count($bad_words_find)) return true; else return false;
}

$x="you soon see redarrow c c";

$word=array("a","see","c");

if (bad_word($x,$word)) echo "You entred a bad word!"; else echo "Word is good!";	
// or
echo '<hr />';
$a = array();
bad_word($x, $word, &$a);
echo 'Bad words is: ',implode(', ', $a);
?>

No need to change your code completely. The code snippet you provided in your first post is nearly there. try this:

<?php

$str = "see you soon redarrow";

$words = explode(' ', $str);

$bad_words = array("a", "see", "c");

foreach($words as $word)
{
    if(in_array($word, $bad_words))
    {
        echo "'$word' - is a bad word!<br />";
    }
    else
    {
        echo "'$word' - is a good word!<br />";
    }
}

?>

[redarrow]

wont work like this why please

 

<?php

$str = "you see redarrow";

$words = explode(' ', $str);

$bad_words = array("a", "see", "c");

foreach($words as $word)
{
   if(in_array($word, $bad_words))
   {
       echo "bad word";
       exit;
   }
   else
   {
       echo "good word";
       exit;
   }
}

?>

[wildteen88]

becuase you are using the exit keyword in your if/else statement

 

Once a match or non maych has been found you are telling PHP to stop and so nothing else happens. and thus you get Good word.

[redarrow]

so if it a good word then update database else dont so i need the exit but how and thank u mate.

[wildteen88]

Is this what you mean:

<?php

$str = "see you soon redarrow";

$words = explode(' ', $str);

$bad_words = array("a", "see", "c");

$bad_words_used = 0;

foreach($words as $word)
{
    // check whether bad words have been used in string
    // if they are we increment the 'bad_words_used' variable by one each time a bad word is used
    if(in_array($word, $bad_words))
    {
        $bad_words_used++;
    }
}

// check to see if 'bad_words_used' variable is greater than 0
// if its greater than 0 we kill script display an error
// if its not greater than 0 we add to database
if($bad_words_used > 0)
{
    die('Bad words have been used');
}
// else badwords have not been used.
else
{
    echo 'No bad words have been used we add to database now';
}

?>
