Parse string containing dots in php

Question

I would parse the following string:

$str = 'ProceduresCustomer.tipi_id=10&ProceduresCustomer.id=1';                 
parse_str($str,$f);

I wish that $f be parsed into:

array(
    'ProceduresCustomer.tipi_id' => '10',
    'ProceduresCustomer.id' => '1'
)

Actually, the parse_str returns

array(
        'ProceduresCustomer_tipi_id' => '10',
        'ProceduresCustomer_id' => '1'
    )

Beside writing my own function, does anybody know if there is a php function for that?

Answer 1

From the PHP Manual:

Dots and spaces in variable names are converted to underscores. For example <input name="a.b" /> becomes $_REQUEST["a_b"].

So, it is not possible. parse_str() will convert all periods to underscores. If you really can't avoid using periods in your query variable names, you will have to write custom function to achieve this.

The following function (taken from this answer) converts the names of each key-value pair in the query string to their corresponding hexadecimal form and then does a parse_str() on it. Then, they're reverted back to their original form. This way, the periods aren't touched:

function parse_qs($data)
{
    $data = preg_replace_callback('/(?:^|(?<=&))[^=[]+/', function($match) {
        return bin2hex(urldecode($match[0]));
    }, $data);

    parse_str($data, $values);

    return array_combine(array_map('hex2bin', array_keys($values)), $values);
}

Example usage:

$data = parse_qs($_SERVER['QUERY_STRING']);

Quick 'n' dirty.

$str = "ProceduresCustomer.tipi_id=10&ProceduresCustomer.id=1";    

function my_func($str){
    $expl = explode("&", $str);
    foreach($expl as $r){
        $tmp = explode("=", $r);
        $out[$tmp[0]] = $tmp[1];
    }
    return $out;
}

var_dump(my_func($str));

array(2) {
    ["ProceduresCustomer.tipi_id"]=> string(2) "10"
    ["ProceduresCustomer.id"]=>string(1) "1"
}
