PHP Regression Tests
====================

To run the tests, go to the top-level directory and
run "./php -q run-tests.php".

Without parameters, "run-tests.php" will recursively scan through the
file tree looking for directories called "tests", and run all the
tests (.phpt files) within (recursively).

To run tests in a single directory, pass the directory as a parameter:
"./php -q run-tests.php tests/lang".

To run one or more single tests, pass them as parameters:
"./php -q run-tests.php tests/lang/015.phpt".

The format of the .phpt files is quite simple.  There are 6 possible
sections.  Test, Skipif, Post, Get, File and Expect.  The Test section
contains the description of the test.  The Skipif section contains
code that should print "skip" if this test should be skipped for some
reason (such as an extension that is not compiled in).  The Post
section contains any post data that the script might need.  The Get
section contains any Get data.  Note that both the Post and the Get
sections need to have this data in url-encoded format.  The File
section contains the actual script and the Expect section is the
expected output, sans headers.  Blank lines are ignored in the
expected output.

A simple example which takes one argument through the POST method
and one through the GET and displays these would be:

--TEST--
Simple GET and POST test
--SKIPIF--
--POST--
a=Hello
--GET--
b=There
--FILE--
<?php echo "$a $b">
--EXPECT--
Hello There

Another simple example that only runs if the PCRE extension is loaded:

--TEST--
Simple Perl regexp test
--SKIPIF--
<?php if (!extension_loaded("pcre")) print "skip"; ?>
--POST--
--GET--
--FILE--
<?php
$str="Hello 42 World";
if (pcre_match('/^([a-z]+)\s+(\d+)\s+([a-z]+)/i', $str, $matches)) {
    printf("%s %s: %d\n", $matches[1], $matches[3], $matches[2]);
}
?>
--EXPECT--
Hello World: 42
