The user receives a truncated message (max. 19109 characters) from a PHP script when mysqli_real_connect is called

I have a problem with 1 of our PHP scripts, it once returns a truncated message.

Flow:

• Custom call in search.php

• The script processes the request:

  • a DB connection
  • b XML assembly using the SimpleXML class
  • c type Paste SimpleXML into a string.
  • d print this line to the client.
• The user receives (output to the browser) only part of the message in some cases

after studying this problem, these are the facts that I found:

• The maximum length is 19109 characters → moreover, that it is truncated.
• I registered the XML string 2.c typeCast and found out that the log contains full XML (not truncated!).
• , / , .

• - :

  • , SimpleXML - XML-String, ( ) diff-hardcoded-XML # 2.d → .

  • , ( diff-hardcoded-XML ), script, "die;". Iv'e , mysqli_real_connect mysql_real_connect , .

, / ?
