I need to separate the string, remove the blank spaces and the arrow, I just want to keep the tags, each one in a different variable. The first one if it comes out but the second one no longer.
$str = 'PD/R --> PPA';
$parte_1 = substr($str,0,strrpos($str, "-")-2).'<br>';
$parte_2 = substr($str, -2);
These labels may vary, for example: 'F --> A' ó 'F --> FJ' . I reiterate, I just want to keep the two labels.
Thank you.
You can use the explode feature to divide your string with reference space. Once this is done, take the first and third positions of the generated array:
$str = 'PD/R --> PPA';
$partes = explode(" ",$str);
$parte1 = $partes[0]; //PD/R
$parte2 = $partes[2]; //PPA
One more example, but this time with preg_split :
$string = 'PD/R --> PPA';
$arrayString = preg_split('/-->\s/', $string); // "\s" elimina los espacios
$parte_1 = $arrayString[0];
$parte_2 = $arrayString[1];
echo $parte_1; //=> PD/R
echo $parte_2; //=> PPA
