[RESOLVED] How many \n are there in the string?

[leetkrew]

hello there,

just a quick question. how to get the number of "\n" (end lines) ?
thanks =)

[man]substr_count/man, perhaps?

thanks...

This is my snippet for those people who needs it. This code will analyze the result if a CSS scroll bar is needed or not.

<div style="{U_IFRAME}"> // content </div>
//--------------------------------
$iframe_html = "overflow:auto;width: 500px;height: 120px;";

while ($row = $db->fetch_array($result) ) {
	// .. .. ..
	if ( substr_count ($text->br($row[content]), "<br>" ) < 5)
		$html_default = preg_replace ("{{U_IFRAME}}", "", $html_default);
	else
		$html_default = preg_replace ("{{U_IFRAME}}", $iframe_html, $html_default);
}

[man]str_replace[/man] would be better than [man]preg_replace[/man]. Does what you're wanting with simpler syntax and faster operation.

i'll consider that. thanks!
