How to unescape string in php?

Question

Given a string like this

$str = '\007\t\007\006\006\t\n\026\r\\\045';

format and output unescaped string so that \t - tabulation and so on.

I could solve this by using replacements, but maybe there is a better solution?

I may be wrong but I don't think $str has valid characters that can be decoded. What do you expect to get as decoded string ? — Pedro Lobito

The best I can think of is:

eval('$str_unescaped = "' . str_replace('"', '\"', $str) . '";');

str_replace is needed in case the string contains any embedded double quotes. But it still gets an error if it contains an embedded \" sequence.

it works! my string also contains '$', added str_replace(['"','$'], ['\"','\$'], $str)
