Multiple foreach statements in PHP script

Question

Here is my current code:

foreach ($swears as $bad_word)
$body = str_ireplace($bad_word, "", $body);

It's filtering bad words, but I'd like to also filter a ":" to a "-" in the body. How can I have multiple foreach statements in my script?

Answer 1

Put them right after each other?

Eg:

foreach($swears as $bad_word)
    $body = str_ireplace($bad_word, '', $body);

$replace_chars = array(
    ':' => '-',
    '?' => '!');
foreach($replace_chars as $char => $rep)
    $body = str_replace($char, $rep, $body);

If you only have one additional character you want to replace, just use str_replace() again, by itself, outside of the foreach(), instead of using the $replace_chars array and the second foreach().

Answer 2

You should just try using http://php.net/manual/en/function.preg-replace.php

Answer 3

Use curly brackets?

foreach( $swears as $bad_word )
{
  $body = str_ireplace($bad_word, "", $body);
  $body = str_ireplace(":", "-", $body);
}

or arrays in str_ireplace:

foreach( $swears as $bad_word )
  $body = str_ireplace(array(":", $bad_word), array("-", ""), $body);

Answer 4

I don't see why you'd need another foreach for that.

foreach ($swears as $bad_word)
    $body = str_ireplace($bad_word, "", $body);

$body = str_replace(":", "-", $body);

But if you did there's nothing stopping you from having another one.

Answer 5

You can use arrays in stri_replace

$body = str_ireplace($bad_words, '', $body);
$body = str_replace(':', '-', $body);

Another way to do it with a single replace, which works well if you have more filter arrays (you could use array_merge to add more replacements)

$filters = $bad_words;
$replacements = array_fill(0, count($bad_words), '');

$filters[] = ':';
$replacements[] = '-';

$body = str_ireplace($filters, $replacements, $body);

Answer 6

All the responses are terrible. You don't need a foreach loop. Here's how it should be done:

 $filter = array(
    ':'      => '-',
    'badword'    => '',
    'anotherbad' => ''
);
$body = str_ireplace(array_keys($filter), $filter, $body);
