After many tests, i have found the right code that did not crash the script.
Issue was in php code not in squid.
while (!feof(STDIN)) {
$url = trim(fgets(STDIN));
if($url<>null){
WLOG($url." str:".strlen($url));
fwrite(STDOUT, "OK\n");
}
}
Thanks

Subject: external_acl_type script crash always after 1mn
Dear i'm trying to build my own external_helper using php.
I have some troubles and i did not see why...
It seems that after 1mn squid claim that helper are crashed.
I did not know why in my code.
i did not see where and how it crash...
You will see that the php code is very simple and do nothing.
So, each minutes or sometimes each 2mn, squid claim :

FATAL: The MyExternACL helpers are crashing too rapidly, need help!
Squid Cache (Version 3.2.1-20120928-r11668): Terminated abnormally.
in squid.conf, i have set this acl:
external_acl_type MyExternACL %SRC %{X-Forwarded-For}>h %SRCEUI48 %URI %DST
%PATH /var/lib/squid3/external_acl_squid.php
My code write the start/stop and process TTL.
You can see that each 60s Squid stop the process or something wrong....

Perhaps my code is wrong ???
here it is the php code
---------------------------------------------------------------------------------------------------------
#!/usr/bin/php -q
<?php
$GLOBALS["F"] = @fopen("/var/log/squid/external-acl.log", 'a');
$GLOBALS["PID"]=getmypid();
$GLOBALS["STARTIME"]=time();
WLOG("starting...");
set_time_limit(0);
while ( $input = @fgets(STDIN) ) {
$Source = trim($input);
if($Source==null){continue;}
if (feof(STDIN)) {
WLOG("break loop");
break;
}
$Source=trim($input);
if($Source==null){continue;}
WLOG($Source." str:".strlen($Source));
echo "OK\n";
}
$distanceInSeconds = round(abs(time() - $GLOBALS["STARTIME"]));
$distanceInMinutes = round($distanceInSeconds / 60);
WLOG("v1.0: die after ({$distanceInSeconds}s/about
{$distanceInMinutes}mn)");
@fclose($GLOBALS["F"]);
function WLOG($text=null){
$date=@date("Y-m-d H:i:s");
if (is_file("/var/log/squid/external-acl.log")) {
$size=@filesize("/var/log/squid/external-acl.log");

unlink("/var/log/squid/external-acl.log");
$GLOBALS["F"] = @fopen("/var/log/squid/external-acl.log",
'a');
}
}
@fwrite($GLOBALS["F"], "$date [{$GLOBALS["PID"]}]: $text\n");
}
