Substring a string using regular expressions

[niroshan]

Hi everyone,
I need to split a string into an array according to a given conditon.Basically its like this,

If we consider the string variable as $str , it has a value as,

$str="<b>this is a test to fetch the data out of a <status>string</status> variable</b>";

the condition is that i want to break this string using <status> and </status> tags.
So when it splits the array element $arr[0] will have the string value bfore the <status> (<status> also included in that) and the $arr[1] wll have the value as "string" (According to my example) and the $arr[2] will have the rest(With </status>)

I can do this with the help of explode function.. but i wants to know is that is there any regular expression function to do this... i tryed eregi() function but didn`t got any results, the code is given below,

$content="<b>this is a test to fetch the data out of a <status>string</status> variable</b>";

eregi('<status>*</status>',$content,$newContent);


while(list($key,$value)=each($newContent))
{
	print $key." = ".$value."<br>";
}

anyone has any idea!!!

thanx in advance,

regards,

You'll need to use preg_match() rather than eregi().

$str = "<b>this is a test to fetch the data out of a <status>string</status> variable</b>";

preg_match("/([^<]*<status>)([^<]*)(<\/status>.*)/i", $str, $arr);

After this, arr[0] will contain the whole string (sorry); $arr[1] will contain the first part up to the contents of the <status> tag; $arr[2] will contain the contents of the status tag; and $arr[3] will contain the rest.

Sorry, pattern should be this:

"/(.<status>)([^<])(<\/status>.*)/i"

[saraadmin]

"/(.<status>)([^<])(<\/status>.*)/i"

It keeps inserting spaces between '<status>' and ')'; they're not supposed to be there!
