array

[pinehead18]

Ok, wow i've just started learning arrays. I found myself in a bind at work were i really need to write this script.

What i need to do and i need to know if it is possible and perhaps maby a little insite on how to accomplish these tasks...

1.) Lets say i have 3 words in an array. Seperated by . the words are one two and three. Is it possible to take the word two out and change it to the word six. While leaving it in the same order in the array. The same order would be "one six three" the wrong order would be "one three six"

2.) I need to write a script that displays all the words in an array. Basically a loop. How might i go about this.

BTW i didn't just come running here to ask hour. I've been reading about arrays for the past couple hours trying to figure something out. I even got a notepad and pen trying to figure something up in my head.
I'm sure it is something easy i just over looked.

Thank you for any help you can provide me.

2) Loop through the array or [man]implode[/man]

$a = array("one","two","three");
foreach($a as $word) {
   echo $word."<br />";
}
//or 
for($i=0;$i<count($a);$i++) {
   echo $a[$i]."<br />";
}
//or
echo implode("<br />",$a);

Not so sure I understand the first one

$a = array("one", "two", "three");
list($one, $two, $three) = $a;

foreach($a as $number) {
  // Replaces "two" with "six"... Just make a str_replace var for each string you want to replace with a diff string.
  $number = str_replace("two", "six", $number);

  echo $number;
}

Just kinda edited Shryku's code..

Cant you just search the array for the word, then replace it?
I dont think str_replace() is required.

$words = array("one", "two", "three");
$key = array_search("two", $words);
if ($key === false) {
	//"two" is not found in $words array
}
else {
	$words[$key] = "six";
}
