[php-src] Issue #10620: php 8 - exit() takes a very long time to send response

Issue: https://github.com/php/php-src/issues/10620 Author: fred-gregorio ### Description <?php $stid= []; $cnt= 0; set_time_limit(600); $epg= simplexml_load_file("epg.xml", "SimpleXMLElement", LIBXML_NOCDATA); if ($epg === FALSE) exit ( "Malformed XML" ); foreach ($epg->programme as $p) { /* just do something.... */ $ev= json_decode(json_encode($p), true); $pieces= explode(" ", $ev['@attributes']['start']); $st= $pieces[0]; $start= strtotime(substr($st, 0, 4)."-".substr($st, 4, 2)."-".substr($st, 6, 2)." ".substr($st, 8, 2).":".substr($st, 10, 2).":".substr($st, 12, 2)); $cnt++; } exit ( "Done, $cnt programs loaded" ) ?> This snipet of code takes around 15 seconds to execute and get to the exit() line. Existing, however, takes 10minutes, until the response is sent. The input file (epg.xml) has around 330,000 nodes. The actual code inside the foreach() loop doesn't realy matters much. Tested with 8.1.14 and 8.2.3 - Same result on both. Executing the same code with php 7.4.28 works fine, taking around 15 seconds to execute and spit out the response. Relevant php configs : max_memory= 256M Test environment: laptop HP, i7 8th Gen, 32GB RAM, 2TB nVme, Windows 11 PRO - 64 bits The input file (epg.xml) is provided gz compressed. [epg.xml.gz](https://github.com/php/php-src/files/10775562/epg.xml.gz) ### PHP Version 8.2.3 ### Operating System Windos 11 64bits
