PHP preg_replace替代方案

Question

We're currently getting a preg_replace error message on our site due to deprecation.

Our code is as follows:

$out = preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $data);

Any suggestions on how this can be replaced with non-deprecated code?

Answer 1

preg_ is not deprecated. It is just /e (as of PHP 5.5):

The /e modifier is deprecated. Use preg_replace_callback() instead. See the PREG_REPLACE_EVAL documentation for additional information about security risks.

and as preg_replace_callback() is almost identical to preg_replace() with exception that it uses callback instead of replacement, update of your code should be quick homework.
