Imagining that I have the following array:
$o_meu_array = array("123_rui", "125_joao", "287_manuel");
Now I want to find inside my array "123". When I find 123, I want to replace 123 with another value given by the user. For example, if the user enters "10", it will become "10_rui". You can do this?

To replace values in a array you can use the function preg_replace()
$meu_array = array("123_rui", "125_joao", "287_manuel");
$procurar = "/123/";
$substituir = "10";
$meu_array = preg_replace($procurar, $substituir, $meu_array);
That was it. Now just one question, is it possible to search for 123 and then replace the name? for example: find: 123 when find replaces the name with Joaquim result: $meu_array = array("123_joaquim", "125_joao", "287_manuel");
@pc_oc That would be https://ideone.com/vGCmko ?
yes, that’s right! Thank you very much!
if the regular expression were with numbers it would look something like this: $search = "/123_([0-9]|[1-9][0-9]|[1-9][0-9][0-9])*/"; right? thanks again
@pc_oc that you would do /123_([0-9])*/, or 123_qualquer_numero_qualquer_size, you can accept letters, numbers, characters, etc., for more information about regular expressions see this link http://www.ibm.com/developerworks/br/library/os-php-regex1/
thanks again!
