How do I do the equiv of ./command<<EOF

Anon

In a UNIX shell script I can do

./command<<EOF
PARAM1=VALUE1
PARAM2=VALUE2
..
..
PARAMn=VALUEn

EOF

How do I do this in a PHP page so that the resulting output can be trapped (in an array)?

Thanks

Hi,

Read the manual, manual/function.exec.html
You can store the result of the command passed in argument into an array.

I've read the manual already. I can use the exec command and get the result in an array. But how do I embed input to the command inside the PHP code?

I'm not sure that will exactly answer your question. But, you could build the command string, then pass it to exec and retrieve the result in an array.

--- BEGIN CODE ---

$params = array();

$params["PARAM1"] = "VAL1";
$params["PARAM2"] = "VAL2";
$params["PARAM3"] = "VAL3";
$params["PARAM4"] = "VAL4";

$cmd = "command<<EOF\n";

while ( list($param, $val) = each($params)) {
$cmd .= "\n$param=$val";
}
$cmd .= "\nEOF";

exec( $cmd, $output );

--- END CODE ---

I have not tried this code and don't know if this may work this way.
If this is not what you need, can you give a little more explanation on your needs.

Thanks,

with a few minor changes that did the job. Here is my finished code

<?
$params=array();
$params[param1] = "value1";
$params[param2] = "value2";

$cmd = "/pathto/binary/binary<<EOF\n";

while ( list($param, $val) = each($params))
{
$cmd .= "$param=$val\n";
}
$cmd .= "\n\nEOF";

exec( $cmd, $output );
