This example shows you how to use your PHP variables in Content Management Systems you may create
with MySQL, or Storing them as files. This makes it a little bit easier instead of adding the PHP
syntax everywhere, but it slows things down. This is going to be used on my Content Management
system in parts.
For example, I will take a string:
$s1='
My dogs name: $mydog
He ate at: $mytime
';
We use Hyphens to preserve the variables. You may want to include a Hyphen replacer to fix hyphens
added to the string. Most likely this block $s1 would come from a Web Form, so some tweaking would
be needed.
Now using my parsing engine, (this is the only way I know how to do it), you can parse the $mydog
and $mytime by calling a function. See below. I was hoping PHP had a built in function, but i spent
less time just making one, than looking for one. PLEASE NOTE I have not tested this with Sessions
yet. So feel free to tweak it up ;)
<?
$mytime=time();
$mydog="My Dog Ate My PHP!";
# Your Parsing String:
$s1 = 'Hyphen Variable Preserving: $mytime, and $mydog';
echo "Before: <br><br>$s1<br><br>";
# Remember, wherever you define this, it will not be defined GLOBAL into the function
# which is why we define it here. Defining it global could lead to security issues.
$vardata=get_defined_vars();
# Parse the string
$s1 = StrParse($s1,$vardata);
echo "After: <br><br>$s1";
function StrParse($str,$vardata) {
# Takes a string, or piece of data, that contains PHP Variables
# For example, unparsed variables like: Test using time: $mytime
# This example shows $mytime, and not the actual variable value.
# The end result shows the actual variable value of $mytime.
# This is useful for building a content management system,
# and directing your variables into your content data,
# where content is stored in a file or database, unparsed.
# Of course this could slow down page loads, but it's a good way
# to parse data from current variables into your loaded new data
# making it compatible.
# Then the variables are replaced with the actual variable..
$getvarkeys=array_keys($vardata);
$ret=$str;
for ($x=0; $x < count($getvarkeys); $x++) {
$myvar=$getvarkeys[$x];
#echo "Variable: " . $myvar . " [" . $vardata[$myvar] .
"]<br>";
$ret=str_replace('$' . $myvar, $vardata[$myvar], $ret);
}
return $ret;
}
?>
