str_replace match only first instance
- by kylex
A followup question to http://stackoverflow.com/questions/3063704/
Given the following POST data:
2010-June-3
<remove>2010-June-3</remove>
2010-June-15
2010-June-16
2010-June-17
2010-June-3
2010-June-1
I'm wanting to remove ONLY the first instance of 2010-June-3, but the following code removes all the data.
$i = 1;
$pattern = "/<remove>(.*?)<\/remove>/";
preg_match_all($pattern, $_POST['exclude'], $matches, PREG_SET_ORDER);
if (!empty($matches)) {
foreach ($matches as $match) {
// replace first instance of excluded data
$_POST['exclude'] = str_replace($match[1], "", $_POST['exclude'], $i);
}
}
echo "<br /><br />".$_POST['exclude'];
This echos:
<remove></remove>
2010-June-15
2010-June-16
2010-June-17
2010-June-1
It should echo:
<remove>2010-June-3</remove>
2010-June-15
2010-June-16
2010-June-17
2010-June-3
2010-June-1
