exec("echo ... issuse

Hello! I want to write a line into a file (called $script) wich goes like that: echo "date 192.168.10.123 is down, lets call the admin. I was sleeping for 10 Minutes | smbclient -M Computer This is what i have tried: exec("echo " echo "date ===> $ip is down, lets call the admin. I was sleeping for $var_timer_rechner1 Minutes" | smbclient -M $popup_1" >> $script"); The problem is that after exec("echo " its command ends due to that ". I tried \" to let php ignore this " but then it doesn´t write my " anymore: exec("echo \" echo \"date ===> $ip is down, lets call the admin. I was sleeping for $var_timer_rechner1\" | smbclient -M $popup_1\" >> $script"); this is the result: echo Wed Sep 25 12:29:17 CEST 2002 ===> 192.168.10.1 is down, lets call the admin. I was sleeping for | smbclient -M Server but i want: echo "Wed Sep 25 12:29:17 CEST 2002 ===> 192.168.10.1 is down, lets call the admin. I was sleeping for" | smbclient -M Server ^^ ^^ missing missing Can anyone tell me where the my mistake is? Cheers, Mario
