How can I extract certain elements from a chain? example:
$cadena="11d08mo2016y";
from which I need to extract only the given numbers of x string separately, thus remaining!
$cadena[0]=11
$cadena[1]=08
$cadena[2]=2016
I was trying the explode function, but apparently it does not destroy the chain in parts, thank you in advance!
$day= explode("d",$cadena);
explode separates by the delimiter that you give it, in this case "d" , so it will bring 2 chains the result [11, 08mo2016y] to the second result you would have to do another explode with the second element and so on, you can do it by recursion or iteration
function explodeFecha($dato) {
$delimitadores = ['d', 'mo', 'y'];
$arreglo = [];
foreach($delimitadores as $delimiter) {
$explodeDato = explode($delimiter, $dato);
$arreglo[] = $explodeDato[0];
$dato = isset($explodeDato[1])? $explodeDato[1] : NULL;
//si usas php 7 o sueperior puedes usar para simplificar
//$dato = $explodeDato[1] ?? NULL;
}
return $arreglo;
}
print_r(explodeFecha('11d08mo2016y'));
It would also be advisable to validate that the format is the desired one so that errors do not appear
The first thing is to eliminate the letters while converting the string at the same time into a array , that you do it by means of the following function:
$cadena="11d08mo2016y";
$array = preg_split('/[^0-9]+/i', $cadena);
Then to make sure there are no blank spaces we filter to array forming a new one without those spaces:
$array_sin_espacios = array_filter($array, function($dato){
if($dato == ''){
return false;
}else{
return true;
}
});
var_dump($array_sin_espacios);
You can use the function preg_split and apply a regular expression, something like this:
$cadena="11d08mo2016y";
$r = preg_split("/[A-Za-z]+/", $cadena);
print_r($r);
