php - Search a string replace a word with array's value -


the idea search string words , change them else according specific array. let me show mean.

$string = "hello buddy, i'm friend or maybe fellow";

let's friends swear word. want change word want. made this:

$swears = array( "friend" => "fri**d", "buddy"  => "bu**y", "fellow" => "fe**ow" );

i want search string according array's key , replace it's value. did search web replace value in array according array key. after trying came this:

$string = "hello buddy, i'm friend or maybe fellow";    $swears = array( "friend" => "fri**d", "buddy"  => "bu**y", "fellow" => "fe**ow" );  $foreach  = $string;  foreach($swears $bad => $good){ $foreach       = str_replace($bad,$good,$foreach); $filtered =  $foreach;  } echo $filtered;

i know works, there easy way feel complicated whole thing. if i'm good, possible may cause problem, if had large string, or take time process it.

str_replace might supplied array of search-words , array of replacers:

<?php $string = "hello buddy, i'm friend or maybe fellow";  $swears = array(     "friend" => "fri**d",     "buddy"  => "bu**y",     "fellow" => "fe**ow" );  echo str_replace(array_keys($swears), array_values($swears), $string); ?>

shows:

hello bu**y, i'm fri**d or maybe fe**ow
