Extracting data from a sring.

[bourbon]

$string = '<object width="425" height="350">';

How do I search the above string to find out what the value of width is and also the value of height.

Thanks in advance

One way of extracting substrings is using one of the regex family functions.
The example below may not be the best implementation, but it should give you an idea...

$string = '<object width="425" height="350">';
$expr=" width=\"([0-9]+)\" +height=\"([0-9]+)";
 
# case insensitive match is good when dealing with HTML tags
if (eregi($expr, $string, $regs)) {
     echo 'width=' . $regs[1] . ' height=' . $regs[2];
} else {
     echo "failed to find a match";
}
 
 

You may want to look at other regex functions (preg_match, etc)
