php - get value of variables defined in shell script -


how can value of variable defined in shell script? (the script configuration file, contains variable-definitions) cannot use "source" command in exec:

echo exec('var=2; echo $var'); //writes "2" echo exec('source config.sh; echo $var'); //writes ""

how can value of variables defined in shell script?

userthis worked me on terminal:

echo var=2 > shellscript echo "<?php echo exec('source /home/user/shellscript; echo $var'); ?>" > phpscript.php ls | grep script phpscript.php shellscript php phpscript.php  2

so wrote shellscript, php read shell script , ran php script. did wanted.

maybe can add other exec components clue?

<?php  echo exec('source /home/user/shellscript; echo $var',$out,$ret);  echo "\nout0: ". $out[0]. "\nret: $ret\n"; ?>

this shows me:

~]$ php phpscript.php  2 out0: 2 ret: 0
