Convert array of delimited strings to variables - php

Question

I need to convert all items in array to variables like:
$item[0] = "apple=5";
$item[1] = "banana=7";
$item[2] = "orange=8";
And I want to convert it to this:
$apple = 5;
$banana = 7;
$orange = 8;
Like normal variables. Is it possible?

Answer 1

Seems like a silly thing to do, why not convert it into an associative array? But if you must:
foreach($item as $x) {
list($name, $val) = explode('=', $x, 2);
$$name = $val;
}

Answer 2

You can try to join the array and parse the string into variables
parse_str(implode('&',$item));

Answer 3

You can do it like this
$item[0] = "apple=5";
$item[1] = "banana=7";
$item[2] = "orange=8";
foreach($item as $row)
{
$new = explode('=',$row);
$array[$new[0]] = $new[1];
}
extract($array);
echo $apple;
echo $banana;
echo $orange;

Answer 4

Your array looks like someone exploded an ini file on its newlines.
Implode with newlines, then parse, then call extract() to generate the variables. (Demo)
extract(
parse_ini_string(
implode(PHP_EOL, $item)
)
);
echo "$apple $banana $orange";
Using explode() or parse_ini_string() or preg_ functions (etc.) will render the numeric values as string-type.
If you'd like the numeric values to be integer-typed, then using %d in the "format" parameter of sscanf() will be most direct. (Demo1)
foreach ($item as $string) {
[$key, $$key] = sscanf($string, '%[^=]=%d');
}
Generally speaking, I do not advise the generation of individual variable (I more strenuously advise against variable variables). Perhaps an associative array would be suitable. (Demo)
$result = [];
foreach ($item as $string) {
[$key, $result[$key]] = sscanf($string, '%[^=]=%d');
}
var_dump($result);
