Hi!
I was wondering if it is possible to use the preg_replace match return value ($1-9) as the key of the array containing the replacement string.
Let me know if anyone knows a solution.
Best Regards,
Snt
preg_replace('REGEX',$arr[$1],$str); using matchvalue as array key

I had some text with numbers that I wanted to use as array references in the replacement text- here's how it worked for me:
$string="My name is [0]";
$names=array("Bill","Bob","Joe");
$string = preg_replace("/[(\d+)]/",$names[(int) ${1}],$string);
echo $string;
output should be "My name is Bill"...
Took me just a bit of playing around to figure this out (newbie), so I thought I would post it here.
it still doesn't work.. this is my code:
$search = array ( '/\{OPTIONS_OBJ_(\d*)\}/Ui',
'/\{OPTIONS_TEXT_(\d*)\}/Ui',
'/\{OPTIONS_POINTS_(\d*)\}/Ui',
'/\{MENU_OBJ\}/Ui',
'/\{MENU\}/Ui',
'/\{QUESTION_NO\}/Ui',
'/\{QUESTION_TEXT\}/Ui',
'/\{TEST_ID\}/Ui',
'/\{TEST_NAME\}/Ui',
'/\{TEST_DESCRIPTION\}/Ui',
'/\{TEST_STATUS\}/Ui',
'/\{TEST_FILENAME\}/Ui'
);
$replace = array ( $options["obj"][(int) ${1}],
$options["text"][(int) ${1}],
$options["points"][(int) ${1}],
$options["menu_objname"],
$options["menu"],
$qn,
$question["title"],
$test_data["id"],
$test_data["title"],
$test_data["description"],
$test_data["status"],
$test_data["filename"]
);
$question_html .= preg_replace($search,$replace,$question["design"]);It seems the (int) ${1} reference doesn't work in search/replace arrays.
Found it:
function option_data($matches) {
global $options;
$arr_data = split("_",$matches[1]);
foreach ($arr_data as $key => $key_data) {
$eval_data .='["'.strtolower($key_data).'"]';
}
eval('$return_value = $options'.$eval_data.';');
if ($return_value) {
return $return_value;
} else {
return $matches[0];
}
}preg_replace_callback('/{(.*)}/Ui',"option_data",$question["design"]);
