[RESOLVED] Basic Loop with [ str_replace]

[Hello-World]

I have a problem with replacing and looping.I need your help please to change
This line

The quick brown {fox} jumps over the lazy {dog}

To this

The quick brown cat jumps over the lazy mouse.

$string = 'The quick brown {fox} jumps over the lazy {dog}';
$arr = array("fox" =>"Cat","dog"=>"mouse");
preg_match_all("/{.*?}/",$testing,$matches);

By the way how to practice looping in php ?
Is there any good exercise for it ?

You are using a preg_match_all when you need to use preg_replace.

Here is one way to do it:

$string = 'The quick brown {fox} jumps over the lazy {dog}';
$arrFrom = array('/{fox}/', '/{dog}/');
$arrTo = array('cat', 'mouse');
$string = preg_replace($arrFrom, $arrTo, $string);
echo $string;

Alternatively, you can group the arrays inside the pattern like so:

$string = 'The quick brown {fox} jumps over the lazy {dog}';
$string = preg_replace(array('/{fox}/', '/{dog}/'), array('cat', 'mouse'), $string);
echo $string;

If you really wanted the loop, you could do it more succinctly as:

<?php
$string = 'The quick brown {fox} jumps over the lazy {dog}';
$arr = array("fox" =>"Cat","dog"=>"mouse"); 

foreach($arr as $find => $replace)
{
    $string = str_replace('{'.$find.'}', $replace, $string);
}

echo $string;
