PHP shell_exec,执行-rwxrwxrwx shell脚本的权限被拒绝

I am currently over ssh on a remote CentOS 5.6 system which runs an Apache webserver. I need to use the poppler pdftohtml binary which, unfortunately, is not currently installed on that machine. So I downloaded the poppler package and built it under my user folder. Since I I am not the system admin, I didn't do

make install

and I have all my compiled files under


The file that I need to execute through php shell_exec() is


If I execute it through my ssh bash, I get the correct output. If I, instead, put this line on a php script:

echo shell_exec("/users/myfolder/poppler-0.18.2/utils/pdftohtml");

I get the following output:

sh: /users/myfolder/poppler-0.18.2/utils/pdftohtml: Permission denied

I tried setting to 777 the file permissions, which currently are -rwxrwxrwx. I also noticed that using shell_exec("whoami"); results in "apache". Shouldn't apache be able to execute the script if the file permissions are -rwxrwxrwx?

I also know that installing poppler through make install would solve the problem but since this is for testing purpose, I would like to avoid "contaminating" the system outside my personal folder until the testing is complete.

Thanks to anyone who will help!
