Localize markers in PHP Array - php

Question

This is quite basic, but I am missing a puzzle piece.
I have a multidimensional PHP array that - among other things - contains some strings. I would like to translate special strings in this array based on a translation table or array in PHP.
$r = array(
0 => 'something',
1 => array(
'othertext' => '1000 {{animals}} and {{cars}}',
'anytext' => '400 {{cars}}',
)
);
In $r, now I would like to replace {{animals}} with another string that is stored in a separate array.
Here it is:
$translations = array(
'animals' => array('Tiere','animaux','bestie'),
'cars' => array('Autos','voitures','macchine'),
);
Now let's set the language / column we want to look up
$langId = 0;
And now, take $r, look for all key that are wrapped in {{}}, look them up in $translations and replace them with key[$langId], so in return we get:
$r = array(
0 => 'something',
1 => array(
'othertext' => '1000 Tiere',
'anytext' => '400 Autos',
)
);
ehm... how's that done?
PS: the marker {{}} is random, could be anything robust

I was able to get the output you expected using the following code. Try it and tell me if it worked for you or not:
<?php
$r = array(
0 => 'something',
1 => array(
'othertext' => '1000 {{animals}} and {{cars}}',
'anytext' => '400 {{cars}}',
)
);
$translations = array(
'animals' => array('Tiere','animaux','bestie'),
'cars' => array('Autos','voitures','macchine'),
);
$langId = 0;
$pattern = "/\{\{[a-zA-Z]+\}\}/";
for($t=0; $t<count($r); $t++) {
$row = $r[$t];
if(!is_array($row))
continue;
foreach($row as $key=>$value) {
if(preg_match_all($pattern, $value, $match, PREG_SET_ORDER)) {
for($i = 0; $i < count($match); $i++) {
//remove {{ & }} to get key
$k = substr($match[$i][0], 2, strlen($match[$i][0])-4);
$replacer = $translations[$k][$langId];
$value = str_replace($match[$i][0], $replacer, $value);
$r[$t][$key] = $value;
}
}
}
}
?>
