I am having trouble working out how to do this, I have a string looks something like this...
$text = "<p>This is some example text This is some example text This is some example text</p> <p><em>This is some example text This is some example text This is some example text</em></p> <p>This is some example text This is some example text This is some example text</p>";I basically want to use something like preg_repalce and regex to remove
<em>This is some example text This is some example text This is some example text</em>So I need to write some PHP code that will search for the opening <em> and closing </em> and delete all text in-between
hope someone can help, Thanks.

$text = preg_replace('/([\s\S]*)(<em>)([\s\S]*)(</em>)([\s\S]*)/', '$1$5', $text);

In case if you are interested in a non-regex solution following would aswell:
<?php $text = "<p>This is some example text This is some example text This is some example text</p> <p><em>This is some example text This is some example text This is some example text</em></p> <p>This is some example text This is some example text This is some example text</p>"; $emStartPos = strpos($text,"<em>"); $emEndPos = strpos($text,"</em>"); if ($emStartPos && $emEndPos) { $emEndPos += 5; //remove <em> tag aswell $len = $emEndPos - $emStartPos; $text = substr_replace($text, '', $emStartPos, $len); } ?>This will remove all the content in between tags.

$text = '<p>This is some example text This is some example text This is some example text</p> <p><em>This is the em text</em></p> <p>This is some example text This is some example text This is some example text</p>'; preg_match("#<em>(.+?)</em>#", $text, $output); echo $output[0]; // This will output it with em style echo '<br /><br />'; echo $output[1]; // This will output only the text between the em

For this example to work, I changed the <em></em> contents a little, otherwise all your text is the same and you cannot really understand if the script works.
However, if you want to get rid of the <em> and not to get the contents:
$text = '<p>This is some example text This is some example text This is some example text</p> <p><em>This is the em text</em></p> <p>This is some example text This is some example text This is some example text</p>'; echo preg_replace("/<em>(.+)<\/em>/", "", $text);[ View output ]

Use strrpos to find the first element and then the last element. Use substr to get the part of string. And then replace the substring with empty string from original string.

format: $text = str_replace('<em>','',$text); $text = str_replace('</em>','',$text);
