I have string like this 1-male,2-female
I want to make this as array like following
array(
1 => male,
2 => female
);
i can make this by using foreach Ex:
$str1 = '1-male,2-female';
$outPutArr = array();
$arr1 = explode(',' $str1);
foreach($arr1 as $str2){
$arr2 = explode('-', $str2);
$outPutArr[$arr2[0]] = $arr2[1];
}
Is there any other short cut to do this?
You can use a simple regex and preg_match_all to simplify it down to:
preg_match_all('/(\d+)-([^,]+)/', $input, $matches);
$array = array_combine($matches[1], $matches[2]);
array_combine mixes it back to:
Array
(
[1] => male
[2] => female
)
Another common approach is utilizing parse_str() after strtr() to replace whatever delimiters your string has into = and &.
$input is your $str1, while $matches is a result variable and by-product that you don't have to provide.This should probably work, although I didn't test it. It's just another way of doing it to give you more options:
$String = "1-male,2-female";
$Array = array();
foreach (array_chunk(explode(array('-', ','), $String), 2) as $Ar)
$Array[$Ar[0]] = $Ar[1];
How it works:
It splits the data into an array of this form:
array('1', 'male', '2', 'female')
That's what the explode is for. Then it rearranges it into chunks of 2 like this:
array(array('1', 'male'), array('2', 'female'))
Last, in a foreach, it merges each array into it's first element (key) and second element (value).
array('1' => 'male', '2' => 'female')
Note that, if an array key is repeated, the value is overwritten.
