The maximum level of nesting of the function "100" is reached, interrupted

Question

I want to create a crawler that receives information about all pages one by one from number 0 to 10,000,000. It doesn't matter how long it takes. I just want it to work. Here is the error I get

  Fatal error: Maximum function nesting level of '100' reached, aborting!  in D: \ wamp \ www \ crawler \ index.php on line 25 

Line 25 is equal

$htmlstr = (string)$this->curlGet($url); 

And there is my full script.

Thank you for your help!

Answer 1

Assuming you are using xdebug, you can set your limit with

 ini_set('xdebug.max_nesting_level', $limit) 

Answer 2

changes the file / etc / mysql / my.cnf parameter to something like max_allowed_packet = 512M

Make sure you have xdebug installed (use phpinfo ()), and then modify the / etc / php 5 / fpm / php.ini file by adding or editing the line: xdebug.max_nesting_level = 1000

Restart both services sudo service mysql restart sudo service php5-fpm restart

If it does not work, you can still set these two parameters to false on / etc / php 5 / fpm / php.ini xdebug.remote_autostart = 0 xdebug.remote_enable = 0

Answer 3

In my case, it was connected with the composer. Some sellers were updated in the composer.json file, but I forgot to run the composer update and installation linker commands. The system generated a cascade of errors that caused this "maximum nested level."

After executing these commands, the problem has been fixed.

Answer 4

Assuming you didn't make a dead stop error, just change the xdebug limit.

I migrated this problem by modifying the xdebug.ini file. (In my mac, the path is / usr / local / php5-5.6.17-20160108-103504 / php.d / 50-extension-xdebug.ini, maybe yours will be slightly different.)

Add a new line at the bottom of the xdebug.ini file:

xdebug.max_nesting_level = 500

Remember: you must change xdebug.ini to match the php you are using. For example, if you installed php5 and xampp on your computer, you need to find out which php you are using.
