Question

Okay, Here's a breakdown of what's up:

1. <? $foo = new Imagick(); ?> works without error when ran from the command-line (e.g., sudo php myscript.php
2. However, when run via the web browswer I get Fatal error: Class 'Imagick' not found in /var/www/lhackwith_www/test_html/magic.php on line 1.
3. magickwand is not installed
4. extension=imagick.so is in imagick.ini which is successfully being read according to phpInfo();
5. However, imagick is NOT showing up in PHP info.

Any advice would be appreciated.

Answer 1

I take it you're absolutely sure you've edited the right php.ini...
Did you check the webserver's error.log for hints? You might want to increase the LogLevel for that test. If it's an apache see http://httpd.apache.org/docs/2.2/mod/core.html#loglevel and http://httpd.apache.org/docs/2.2/logs.html#errorlog

or maybe ldd - print shared library dependencies can shed some light on the issue:

<?php
$p = get_cfg_var('extension_dir');
$modpath = $p.DIRECTORY_SEPARATOR.'imagick.so';
echo $modpath, is_readable($modpath) ? ' readable':' not readable', "<br />
";
echo '<pre>';
passthru('ldd '.$modpath.' 2>&1'); // in case of spaces et al in the path-argument use escapeshellcmd()
echo '</pre>';

please run this script both on the command line and through the webserver. Does it complain about a missing dependency?


edit2: So the script running "within" the webserver isn't even able to see the extension .so... Let's test at which point of the path the trouble starts

<?php
function foo($path) {
  if ( $path==($dir=dirname($path)) ) {
    return;
  }
  foo($dir);

echo
    is_dir($path) ? ' d':' -',
    is_readable($path) ? 'r':'-',
    is_writable($path) ? 'w':'-',
    is_executable($path) ? 'x ':'- ',
    $path, "<br />
";
}

$modpath = get_cfg_var('extension_dir').DIRECTORY_SEPARATOR.'imagick.so';
foo($modpath);
