Good morning. Thank you very much in advance.. How can I get the content inside the brackets?
lang[en-US].php
lang[pt-BR].php
In fact it is a list of files that are inside a folder:
$atual = $ap . $dir . '/' . $file;
if(is_file($atual)) {
echo '<li>'.$file.'</li>';
}
But I want $file , which corresponds to ex: lang[pt-BR].php , print only what is between the brackets. EX: pt-BR
There are several ways.
What I would prefer, for being more practical (= P):
Use explode , which breaks the string where it determines.
<?php
$texto = 'lang[en-US].php';
// Seu $texto
$texto = explode('[', $texto);
// $texto agora possui: [0] => 'lang', [1] => en-US].php
$texto = explode(']', $texto[1]);
// $texto agora possui [0] => en-US, [1] => .php
echo $texto[0];
// Resultado: en-US
STRISTR: I want something with fewer rows!
You can use stristr , which has a function similar to explode , together with str_replace .
$texto = 'lang[en-US].php';
$cortado = stristr(stristr($texto, '['), ']', true);
// Escolha um para remover os [:
$texto = str_replace('[', '', $cortado);
// OU
$texto = substr($cortado, 1);
REGEX: I want to use REGEX
Because REGEX is the three rule of programming.
$texto = 'lang[en-US].php';
preg_match('/\[(.*?)\]/', $texto, $cortado);
// Escolha um para remover os []:
$texto = str_replace('[', '', str_replace(']', '', $cortado[0]));
// OU
$texto = substr($cortado[0], 1, -1);
//OU
$texto = $cortado[1];
Note:
The
str_replacecan be changed bysubstr.
You can use preg_match () :
PHP
$atual = $ap . $dir . '/' . $file;
preg_match('/\[(.*)\]/', $file, $matches);
if(is_file($atual)) {
echo '<li>' . $matches[1] . '</li>';
}
Explanation of regular expression
\[ encontra o caracter [ literalmente
Primeiro grupo a ser capturado (.*)
.* encontra qualquer caracter (exceto quebra de linha)
Quantificador: * Entre zero à ilimitadas vezes
\] encontra o caracter [ literalmente

As @Inkeliz pointed out, there are several ways to get the solution. Personally, I would also use the @Inkeliz solution:)
I'll leave my answer just to have another solution to the problem.
