Rewriting anonymous PHP functions
In newer versions of PHP, create_function is an deprecated function. An example will be given of rewriting such a function.
create_function the function is unsafe due to the fact that it calls the function inside eval ().
We will change it using the example of one of the plugins in WordPress
We look at the site, we see there create_function:
if (!empty($ tags)) {
$ post_tags = ''['[‘ . implode(',', array_map(
create_function('$ v', 'return "'". urlencode (substr ($ v, strpos ($ v, '_ ') + 1)). " '";'), $ tags)) . ']'';
} else {
$ post_tags = ''[]'';
}
$ post_tags = ''['[‘ . implode(',', array_map(
create_function('$ v', 'return "'". urlencode (substr ($ v, strpos ($ v, '_ ') + 1)). " '";'), $ tags)) . ']'';
} else {
$ post_tags = ''[]'';
}
This:
create_function('$ v', 'return "'". urlencode (substr ($ v, strpos ($ v, '_ ') + 1)). " '";')
Rewrite it
$ ploshadka = function($ v) {
$ strop = strpos($ v, '_');
$ substr = substr($ v, $ strop + one);
return urlencode($ substr);
};
$ strop = strpos($ v, '_');
$ substr = substr($ v, $ strop + one);
return urlencode($ substr);
};
