Delete Before and after a string in PHP

I cannot find any info on deleting before and after a string.

example :

$string = 'Experts are ready to help solve your<a class ='problem' href='bla.php'>go there</a>. The quality of your question will directly ';

lets say i want the name of the href, how would i go about this?

Finished string

"bla.php"

According to HTML 4.01, <a hrefs do not have names.  Named anchors are for locating place within the current page.

In PHP, you can locate items in a string with strpos() or one of the other string position funtions found on this page: http://us.php.net/manual/en/function.strpos.php .  There are notes there about the "=== operator" for checking the results.

I am using the href as a example.

can you find me with a php script everything after
href='
and before
'>
and put that into a string.

or everything after '> and before </
the string should be "go there"

I just want find out how to do this.


I thank you in advance.

There are a lot of examples on the php.net pages.  Usually you use strpos() to find the start of what you want and then substr() to extract it.  You actual method will depend on the data you're working with.

Your string example above will fail because you have 6 single quotes and no way for php to know what you mean.  Normally, you would either use double quotes on the ends or escape (\') the single quotes in the middle so php know where the correct start and end of the string is.

preg_match_all("/href=?[^<]+/i",$str,$lnk);// get link and text

foreach($lnk[0] as $linkdata)
{
	preg_match("/href=?[^>]+/i",$linkdata,$single_link);
	$link = substr($single_link[0],5);//remove href=
	$link = trim($link,"'\"");//remove double or single quote

	preg_match("/[>]+[a-z,A-Z, ,0-9]+/i",$linkdata,$link_text);
