str_replace clarification!!!!!

[mikefrederick]

why does this not work? it replaces each $x in the array with the actual word array rather than the original word.

 

$bar = $_GET['letters'];
$x=explode(" ",$bar);
$a=str_replace($x,"<span style='color: #000066; font-weight: 600'>" . $x . "</span>",$t);

because you need to use str_replace on a string variable  in your case $x is an arrary

[mikefrederick]

how do I do this then? I mean you can use an array for the value you want to replace, why not for the value you are replacing it with

[rhodesa]

because $x is an array

 

try this:

$a=preg_replace("/\$x/,"<span style='color: #000066; font-weight: 600'>$1</span>",$t);

 

Update: scratch the above...posting another one is sec

[cooldude832]

PHP replacement type functions or search functions work on a principle of needle in a haystack

meaning your needle (must be integers or string mostly) is searched for in a haystack (most var types integers, string, arrays) 

 

You must do a foreach and replace each node of $x individually or some alternative method

 

Edit:

if that isn't clear

your needle is your original string, and the haystack is your query pool what is to be found.  I think I stated it backwards:)

<?php

  foreach(explode(" ",$bar) as $x)

    $t = str_replace($x,"<span style='color: #000066; font-weight: 600'>{$x}</span>",$t);

?>
