将字符串内容放入数组php中

Question

I have this string

string(2091) "


"roots" => array(
    array(
        "driver"        => "LocalFileSystem",   // driver for accessing file system (REQUIRED)
        "path"          => "../files/",         // path to files (REQUIRED)
        //"URL"           => dirname($_SERVER["PHP_SELF"]) . "/../files/", // URL to files (REQUIRED)
        "accessControl" => "access" ,            // disable and hide dot starting files (OPTIONAL)
        "alias" => "Root",
        //"uploadDeny"    => array("all"),
        "attributes" => array(
    array(
        "pattern" => "/\manuali$/",  //You can also set permissions for file types by adding, for example, <b>.jpg</b> inside pattern.
       // "pattern" =>"/\PROVA$/",
        "read" => true,
        "write" => false,
        "locked" => true,
    ),
    array(
        "pattern" => "/rapporti$/",  //You can also set permissions for file types by adding, for example, <b>.jpg</b> inside pattern.
       // "pattern" =>"/\PROVA$/",
        "read" => true,
        "write" => true,
        "locked" => true,
    )
     [...]
     ";

i want to put into array the entire value of a string. Ex:

array(


"roots" => array(
    array(
        "driver"        => "LocalFileSystem",   // driver for accessing file system (REQUIRED)
        "path"          => "../files/",         // path to files (REQUIRED)
        //"URL"           => dirname($_SERVER["PHP_SELF"]) . "/../files/", // URL to files (REQUIRED)
        "accessControl" => "access" ,            // disable and hide dot starting files (OPTIONAL)
        "alias" => "Root",
        //"uploadDeny"    => array("all"),
        "attributes" => array(
    array(
        "pattern" => "/\manuali$/",  //You can also set permissions for file types by adding, for example, <b>.jpg</b> inside pattern.
       // "pattern" =>"/\PROVA$/",
        "read" => true,
        "write" => false,
        "locked" => true,
    ),
    array(
        "pattern" => "/rapporti$/",  //You can also set permissions for file types by adding, for example, <b>.jpg</b> inside pattern.
       // "pattern" =>"/\PROVA$/",
        "read" => true,
        "write" => true,
        "locked" => true,
    )
     [...]
     );

i have tried str_split() implode() array_push()... but every function put the string into array in this mode array(string(" "))i want to put in this mode array(" ").

Thanks

If your string is parseable and you don't mind about possible injections, you can simply eval your array representation.

For example, if your string is in $arrayStr and you want to create an array $myArray from that:

$arrayStr = '"roots" => array ( ... )';
eval('$myArray = array(' . $arrayStr . ');');

Note that if $arrayStr is not entirely controller by you from generation to conversion, it is highly risky since anything in it would be evaluated.

A better solution to exchange a whole array between parts of your application would be to serialize() it beforehand to create a string representation of your array/object which can be stored, and then unserialize it when you need it in its original form.
