I have problem with that code so please send me answer as soon as possible.
echo "<pre >";print_r($q) echo"</pre>";

Correct format to print reocrds is
echo "<pre>";
print_r($q);
echo"</pre>";

You are missing the delimiter ';' after print_r
echo "<pre >"; print_r($q); echo "</pre>";

plase add semi column (';') after print_r statement
echo "<pre >";print_r($q); echo"</pre>";

I'm trying to figure out how to grab the string inside H1 without actually H1 inside the string.
$html = "<div id="test"><h1>hello world</h1></div>"
foreach($html->find('div[id=test] h1') as $test1){
echo '<div>';
echo $test1;
echo '</div>';
}
$test1 returns "<h1>hello world</h1>"
I'd like for $test1 to be just "hello world" and without the h1 tags. Thank you in advance
You can use regex for this:
$str = '<div id="test"><h1>hello world</h1></div>';
$matches = array();
preg_match('/<h1>(.*)<\/h1>/', $str, $matches);
echo $matches[1];
Outputs: hello world

Follow this LINK
You can also make use of htmlentities()

I need to echo a paging function twice,
echo blaetterfunktion($seite, $wieviele_seiten);
content
echo blaetterfunktion($seite, $wieviele_seiten);
I guess that would burden the server twice?
What can I do to have the server burdened just once and still echo it twice?
Place the result of the function in a variable:
<?php
$result = blaetterfunktion($seite, $wieviele_seiten);
echo $result;
?>
content
<?php
echo $result;
?>
Save it to a variable:
<?php
$variable = blaetterfunktion($seite, $wieviele_seiten);
echo $variable;
?>
content
<?php
echo $variable;
?>

foreach(glob($select)) as $filename){
echo $filename;
echo "<a class='vlightbox1' href='$filename' title='$filename'><img src='$filename' style='height:120px; width:160px; alt='$filename'></a>";
echo "<a href='ap_deleteimages.php?id=$filename'>Delete</a>";
}
It is not working Properly. I Have Added $select Value as under
$select=document.write(document.getElementById('flist').value)
and 'flist' is a option tag id in html and glob function do not work with it
foreach(glob($select) as $filename){
echo $filename;
echo "<a class='vlightbox1' href='$filename' title='$filename'><img src='$filename' style='height:120px; width:160px; alt='$filename'></a>";
echo "<a href='ap_deleteimages.php?id=$filename'>Delete</a>";
}
You have the syntax error at glob function in your code. The right syntax is in above code.
Second thing is that glob() is used to find all the search pathname matching a pattern. So you need to check that the value of $select is correct or not.
Read more above glob() function.
How about putting in the parentheses?
foreach ( glob($select) as $filename)

The simple program is not returning the string,Please help.
<?php
function returnStr() {
return "fooBar";
}
$str=returnStr();
echo $str;
}
?>
It's a parse error:
$str=returnStr();
echo $str;
} // WHAT IS THIS BRACKET DOING HERE?
There's a fatal error tokenizing the code due the trailing/unmatched '}' remove that and the code will work. Then spend some time thinking about why you didn't know this already
There's an error in your code. The last } is useless.
