Top Forums Shell Programming and Scripting Use of expr to calc differenc ein to epoch values Post 303016665 by Don Cragun on Tuesday 1st of May 2018 10:12:22 PM

At the time that you define DATE_DIFF, INSERT_TIME has not yet been set. So DATE_DIFF, if your script were run now would provide an assignment similar to:
Code:
DATE_DIFF=`expr 1525226185 - `

which gets a syntax error when running expr because - is a binary operator and there is no second operand.

Maybe you meant to create a function named DATE_DIFF instead of a variable named DATE_DIFF?

svn_checkout - Checks out a working copy from the repository

SYNOPSIS
bool svn_checkout (string $repos, string $targetpath, [int $revision], [int $flags]) DESCRIPTION
Checks out a working copy from the repository at $repos to $targetpath at revision $revision. PARAMETERS
o $repos - String URL path to directory in repository to check out. o $targetpath - String local path to directory to check out in to Note Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the calling script's working directory, use realpath(3) or dirname(__FILE__). o $revision - Integer revision number of repository to check out. Default is HEAD, the most recent revision. o $flags - Any combination of SVN_NON_RECURSIVE and SVN_IGNORE_EXTERNALS. RETURN VALUES
Returns TRUE on success or FALSE on failure. NOTES
Warning This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk. EXAMPLES
Example #1 Basic example This example demonstrates how to check out a directory from a repository to a directory named calc: <?php svn_checkout('http://www.example.com/svnroot/calc/trunk', dirname(__FILE__) . '/calc'); ?> The dirname(__FILE__) call is necessary in order to convert the calc relative path into an absolute one. If calc exists, you can also use realpath(3) to retrieve an absolute path.
