I have the following String:
$link = '13542345/essa_e_minhastring';
How do I get only the value up to the "/" bar and ignore the rest?
I'd like to assign this value to a variable.
I'm using the following code, but it just breaks the string ... and does not separate into a variable as I need:
$cod = str_replace("/","<br>",$link);
echo $cod;
The result is:
13542345
esse_e_minhastring
I need it to be just:
13542345
You can break the string by / using explode() and then use only the first part like this:
$partes = explode("/", $link);
echo $partes[0]; // dá 13542345
Example: link
Another alternative is to use regex like this:
$link = '13542345/essa_e_minhastring';
$pattern = '/[^\/]+/';
preg_match($pattern, $link, $partes, PREG_OFFSET_CAPTURE);
echo $partes[0][0]; // dá 13542345
Example: link
I did a test between explode , preg_match , strtok and substr . The test certainly sins because it is so simple and isolated, and therefore not real. But it's interesting. The result between the 4 methods is:
7.9003810882568E-8 sec / por explode
2.0149707794189E-7 sec / por preg_match // <- mais rápida
4.8128128051758E-8 sec / por strtok
5.2464962005615E-8 sec / por substr
The function strstr() , breaks a string by a delimiter and returns the right part by default, passing the third argument to true return is the left part.
$link = '13542345/essa_e_minhastring';
echo strstr($link, '/', true);
Another option is explode() , it transforms the string into an array, just grab the first one element (zero index).
This syntax works from 5.4
$link = '13542345/essa_e_minhastring';
$numero = explode('/', $link)[0];
echo $numero;
for lower versions do:
$link = '13542345/essa_e_minhastring';
$numero = explode('/', $link);
echo $numero[0];
Use the substr () function;
It takes the contents to the bar and continues as a string;
$text = "123456/efineinfe";
$text = substr($text, 0, strpos($text, "/"));
