<a param1="false" class="param2" id="id#12" href="#1">toto</a>
I have made a preg_replace in PHP to remove certain params in a html text:
$re = "/(param1=\"false\"|class=\"param2\"|id=\"id#([^\"]+)\")/";
$text = preg_replace($re, " ", $data->text->value);
I obtain this html link:
<a href="#1">toto</a>
I would like to leave only one space beetween the and the href, is it possible to do that directly in the regex ?
Change your regular regular in the following way,
$re = '/(param1="false"\s+|class="param2"\s+|id="id#([^\"]+)"\s+)/';
You need to pass \s+ in each of your component.
And change your preg_replace() function in the following way,
$text = preg_replace($re, "", $data->text->value);
Don't replace them with space, that's it.
Assuming you have to use all the backrefrences in your "preg_match". This is the only way you can accomplish
$re = "/<a.*(param1=\"false\"|class=\"param2\"|id=\"id#([^\"]+)\")/";
$text = preg_replace($re, "<a", $data->text->value);
You could try this:
$re = "/(param1=\"false\"|class=\"param2\"|id=\"id\#([^\"]+)\")([\ ]{1,}?)/";
$text = preg_replace($re, "", $data->text->value);
