Take part of a string delimited between characters
I have a string like the one in the example below:
$string = 'Lorem ipsum dolor sit amet, consectetur /adipiscing elit/.';
My question is, how can I take only the part of the text that is between the bars /, and at the same time take that part out of the main string?
Would have to be like:
$string = 'Lorem ipsum dolor sit amet, consectetur.';
$retirado = 'adipiscing elit';
I used this text as an example, but I can have this markup with // on more than one part of my string, and I would need to take all those parts separately and pull out of string main;
Example:
$string = 'Lorem ipsum /dolor sit amet/, consectetur /adipiscing elit/.';
Expected output:
$string = 'Lorem ipsum, consectetur.'
$retirado = 'dolor sit amet adipiscing elit';

You should use preg_match_all when there are multiple values, see their documentation here!
To "paste":
This is to only get the data between "/", in this way you will be able to get "what you have" between the "/". You will also get to use them to replace. Since your post says you need "$string "and also the "retir removed", this would be a better solution.
// Sua string:
$string = 'Lorem ipsum /dolor sit amet/, consectetur /adipiscing elit/';
// Regex (leia o final para entender!):
$regrex = '/\/(.*?)\//';
// Usa o REGEX:
preg_match_all($regrex, $string, $resultado);
You will get exactly, in the variable resultado result:
array(2) {
[0]=>
array(2) {
[0]=>
string(16) "/dolor sit amet/"
[1]=>
string(17) "/adipiscing elit/"
}
[1]=>
array(2) {
[0]=>
string(14) "dolor sit amet"
[1]=>
string(15) "adipiscing elit"
}
}
So you can do one:
foreach($resultado[1] as $texto){
echo $texto;
}
Will get:
dolor sit amet
adipiscing elit
To remove:
Using the data already obtained with preg_match_all:
This is useful if you need to get the data using
preg_match_all, in this way it will only replace what you already have!
$string = 'Lorem ipsum /dolor sit amet/, consectetur /adipiscing elit/.';
$resultado = str_replace($resultado[0], "", $string);
echo $resultado;
// Retorna:
Lorem ipsum , consectetur .
Using preg_replace:
This solution does not fully answer the question, as the author demands the " withdrawn$"! For other cases, when there is only a need to replace, without obtaining any data, you can use such a method.
$string = 'Lorem ipsum /dolor sit amet/, consectetur /adipiscing elit/.';
$resultado = preg_replace('/\/(.*?)\//', "" , $string);
echo $resultado;
// retorna:
Lorem ipsum , consectetur .
About REGEX:
Regex is the main one of this function, so I must at least explain minimally.
/ Inicio do Regex!
\/ Escapa o "/" ("encontre a "/")
(.*?) Obtenha qualquer caractere
\/ Escapa o "/" ("encontre a "/")
/ Fim do Regex (como estamos com o preg_match_all seria o mesmo de /g)
This way the REGEX executes something like:
Find the"/", get anything until you find the next"/", thus getting everything between the"/".
In this case you can use one of the functions split of PHP
One of the simplest ways would be by using explode() which would look like this:
$string = 'Lorem ipsum dolor sit amet, consectetur /adipiscing elit/.';
$pices = explode("/", $string);
//Array ( [0] => Lorem ipsum dolor sit amet, consectetur [1] => adipiscing elit [2] => . )
In this case the function explode() generates an array with the string.
In addition you can use the functions:
preg_split
or
preg_replace
In this case you would use regular expressions
I hope I helped.
Update
For present separately you can do like this:
foreach ($pices as $key => $value) {
echo "<p><strong>Pedaço $key: </strong>$value</p>";
}
You can use preg_replace, as shown below:
preg_replace("/\/(.*\//", "", $string);
Function split_me ($string, start start, {end) {
STR str2 = substr (substr ($string, stripos (str string, start start)), strlen (STR start)); $b = stripos (STR str2 ,end end); return trim (substr (STR str2, 0 ,b b)); }
$string = ' Lorem ipsum dolor sit amet, consectetur / adipiscing elit/.'; Echo split_me($string,'/','/');
Try doing like this:
$string = 'Lorem ipsum /dolor sit amet/, consectetur /adipiscing elit/.';
function removeParseContentBar($string)
{
$arr = str_split($string);
$i = 0;
foreach ($arr as $k => $char) {
if ($char == '/') {
/* abre a tag na primeira barra e
fecha o elemento em tag quando
achar a segunda barra */
$arr[$k] = ($i % 2 == 0) ? '<' : '/>';
} else {
$arr[$k] = $char;
$i++;
}
$i++;
}
$content = implode('', $arr);
//remove a tag
return strip_tags($content);
}
echo removeParseContentBar($string);
