Hi,
The simplest way (actually the single way I know :) ) would be to
capture the output using output buffering functions, something like this:
// start output buffering
ob_start();
// include the file that generates the HTML (or whatever content)
include "....";
// get output buffer content
$output=ob_get_contents();
// clean output buffer and stop buffering
ob_end_clean();
// the content generated in the included file is now in $output variable
// use it as you consider fit
.........

Output buffering will do it.
Also I am not sure but did you try retrieving content with fopen() ?
Something like
$file = 'invoicetable_bottom.php';
fopen("http://yoursite.com/folder/$file","r";);
http://tr.php.net/function.fopen
worth trying. Easier than output buffering

This would not work. fopen would open the file for read. What you would be
reading is the actual source of the document. Not the data the script would
output when ran.
The ob_* functions are the only way that I know of to do what you are asking

That's just crazy talk. If you use fopen on a web URL, then it will
always return the output the script generates. That's how http works!

Morning!
Just a quick question.
Say I have a column in my database that could contain NULLS, empty spaces,
or an actual value.
If I do:
$my_query = "SELECT my_column FROM my_database WHERE 1 = 1";
$my_result = ifx_query($my_query, $connect_id);
while($row = ifx_fetch_row($my_result)) {
$my_column = trim($row['my_column']);
if ($my_column != "") {
echo "Test";
}
}
The way PHP assigns the query results to the $my_column variable, wouldn't;
if ($my_column != "") not do anything for the rows that contained NULLS or
empty spaces?

using empty() is ´the right way to check a var for NULL or ""
however, it also depends what MySQL has got as setuo definition for empty
fields. on textfields u can define an epmty string as default.

As long as I trim() the result, if (!empty()) would skip any results where
the column contains " " OR "NULL", correct?

Empty will also match a string containing 0. And, to me, that doesn't at
all seem empty :)

if it can take only numeric values u can use is_numeric()
also i suggest that you not to use nulls in dbs. instead, use "not null" and
"default value" property. Its more simple and more effective for both managing
your database and coding your program.

Or you could leave the database with the nulls in, and cast the value
explicitly as an integer with intval() or floatval() which will always
give you a numeric value.

It's a CHAR (60) field.
This database has been around for close to a decade and I'm not the DBA for
it. And with several billion records and 1000's of tables I don't see them
getting updated/changed. (The gov't doesn't like change)

If this is correct, why not do it in the SELECT statement to begin with?
$my_query = "SELECT my_column FROM my_database WHERE my_column IS NOT NULL";
That should do it.

I don't think you're using mysql, but your selected db may have a
similar option. I would do the work in the sql.
<?php
$sql = "SELECT * FROM `table` WHERE TRIM(`column`) <> '' AND `column`
IS NOT NULL";
$result = query($sql);
while ($row = fetch_row ($result)) {
echo "Not empty, multiple spaces or NULL!";
}
?>
So, if you have any extraneous spaces, they will be removed. It also
accounts for nulls. No work is required by PHP to determine the values
you need. Just use what it returns. This should work.
Hope this helps.

This might help some people struggling with memory leak problems in
DOMPDF. I haven't fixed it but it seems to have reduced the memory leak
considerably.
I have done 2 things:
1.
Added a detruct function to the DOMPDF file in dompdf.cls.php where I
unset everything. I call this each time in my loop when I'm using DOMPDF
mulitple times:
function __destruct()
{
unset($this->_messages);
unset($this->_xml);
unset($this->_tree);
unset($this->_css);
unset($this->_pdf);
unset($this->_paper_size);
unset($this->_paper_orientation);
unset($this->_base_host);
unset($this->_base_path);
unset($this->_cache_id);
}
2.
I now added within the render function of DOMPDF a call to the function
dispose to clean up anything left from before:
// This is where the magic happens:
$root->reflow();
// Memory leak fix
$root->dispose(true);
// Clean up cached images
Image_Cache::clear();
Also worth mentioning that I increased my memory allocation in my
php.ini to about 256MB, and the max execution time to about 120 seconds.
As mentioned this won't fix the problem but it does reduce the memory
used.

Good morning Everyone,
I'm have trouble with a simple HTML Checkbox list. I keep getting *Parse
error*: syntax error, unexpected '>'. I'm sure I'm doing something really
simple and basic wrong I just cannot seem to see what it is, any assistance
is appreciated.
Script:
<form method="post" action="http://bw.org/misc/cgi-test/test.cgi";>
<?php
$sql = "SELECT * FROM melstatus WHERE custID=$custID ORDER BY
aircraftRegistration";
$q = mysql_query($q)
or die ("could not execute query.");
echo " <fieldset>
<ul style='list-style: none'>\n;
while($row = mysql_fetch_array($q))
{
echo " <li>".$row['melID']."<input type="checkbox"
name="\".$row['melID].\""/input> ";
</li>\n";
}
echo "</ul></fieldset>
?>
</form>
Many Thanks

You're escaping in the wrong places. The \ escapes the character
following it, so what you are doing here, in line 2, is breaking out of
the string with a regular " and then printing a " (escaped \") Also, I
think you need to brush up on your HTML a bit, as
<input type="checkbox" name="name"/input>
is not valid HTML.
Thanks,
Ash

Reading again, it's not just one miss. You have to close some strings, escape
some quotes, etc
I think this can be right:
$sql = "SELECT * FROM melstatus WHERE custID=$custID ORDER BY
aircraftRegistration";
$q = mysql_query($q)
or die ("could not execute query.");
echo " <fieldset>
<ul style='list-style: none'>\n";
while($row = mysql_fetch_array($q))
{
echo " <li>".$row['melID']."<input type=\"checkbox\"
name=\"".$row['melID']."\"/> ";
echo "</li>\n";
}
echo "</ul></fieldset>";
I'd recomend you to get a good text editor with sintax highlighting if you
haven't one. It would warn you from most of these mistakes.
And an xhtml issue: to use an empty tag, you use <tag/> and not <tag/tag>

You missed a double quote here:
echo " <fieldset>
<ul style='list-style: none'>\n";

Asunto: [PHP] Parse error: syntax error, unexpected '>'
Good morning Everyone,
I'm have trouble with a simple HTML Checkbox list. I keep getting *Parse
error*: syntax error, unexpected '>'. I'm sure I'm doing something really
simple and basic wrong I just cannot seem to see what it is, any assistance
is appreciated.
Script:
<form method="post" action="http://bw.org/misc/cgi-test/test.cgi";>
<?php
$sql = "SELECT * FROM melstatus WHERE custID=$custID ORDER BY
aircraftRegistration";
$q = mysql_query($q)
or die ("could not execute query.");
echo " <fieldset>
<ul style='list-style: none'>\n;
while($row = mysql_fetch_array($q))
{
echo " <li>".$row['melID']."<input type="checkbox"
name="\".$row['melID].\""/input> ";
</li>\n";
}
echo "</ul></fieldset>
?>
</form>
Many Thanks
Haig

Hi there, i've the following strings:
$string1 = 'Lorem ipsum dolor http://site.com sit amet';
$string2 = 'Lorem ipsum dolor http://www.site.com/ sit amet';
$string3 = 'Lorem ipsum dolor http://www.site.net sit amet';
How can I extract the URL from these strings?
They can be [http:// + url] or [www. + url].

Something like this should work for you.
<plaintext><?php
$urls[] = 'Lorem ipsum dolor http://site.com sit amet';
$urls[] = 'Lorem ipsum dolor https://www.site.com/ sit amet';
$urls[] = 'Lorem ipsum dolor www.site1.net sit amet';
$urls[] = 'Lorem ipsum dolor www site2.net sit amet';
foreach ( $urls AS $url ) {
if ( preg_match('%((https?://|www\.)[^\s]+)%', $url, $m) ) {
print_r($m);
}
}
?>
Actually, try this. It seems to work a little better.
<plaintext><?php
$urls[] = 'Lorem ipsum dolor http://site.com sit amet';
$urls[] = 'Lorem ipsum dolor https://www.site.com/ or http://www.site2.com/'
;
$urls[] = 'Lorem ipsum dolor www.site1.net sit amet';
$urls[] = 'Lorem ipsum dolor www site2.net sit amet';
foreach ( $urls AS $url ) {
if ( preg_match_all( '%(https?://[^\s]+|www\.[^\s]+)%',
$url,
$m,
(PREG_SET_ORDER ^ PREG_OFFSET_CAPTURE)
) ) {
print_r($m);
}
}
?>
What if the sub domain was not 'www'?
http://no-www.org/
Cheers,
~Philip
