Hello, I need to assign multiple array to a single variable, the value of all of them will be in sequence in that variable. Ex.:
$variavel = $array[0] . $array[1] . $array[2] . $array[3] . $array[4];
echo $variavel
This variable then uses it in an IF to make multiple comparisons, how can I do this without having to write infinite array assignments?
Use implode to join / concatenate array values
echo implode(array);
See the result: link
On if , if comparisons are made, it is better to treat the array directly.
You can use the following functions:
in_array - search if a value exists in the array; array_filter - filter the array and return the values that passed through the filter; array_reduce - applies a function and reduces an array to a single value. The two previous functions are the most recommended, however, if you need to, you can apply a function and return true / false. Comparing the string directly may not yield consistent results. I will not go into performance issues as there is no need.
change:
echo $variavel;
To:
echo serealize($varialvel);
or
echo json_encode($variavel);
