pcre.backtrack_limit sets the maximum bind length PREG calls (e.g. preg_replace_callback) can make. However the actual maximum seems to be approximately half the value set here, possibly due to the character encoding that PCRE runs with internally.pcre.backtrack_limit can be set to -1;
ini_set("pcre.backtrack_limit", "-1");
after i put the above code in my code, it works;
so i guess -1 means infinite(i am not very sure ,but it works);
so when you have not idea how much it should be set in your program, you can try this.
