11.12. Removing HTML and PHP Tags
11.12.2. Solution
Use strip_tags( ) to remove HTML and PHP tags from a string:
$html = '<a outsideurl=">I <b>love computer books.</b></a>'; print strip_tags($html); I love computer books.
Use fgetss( ) to remove them from a file as you read in lines:
$fh = fopen('test.html','r') or die($php_errormsg);
while ($s = fgetss($fh,1024)) {
print $s;
}
fclose($fh) or die($php_errormsg);11.12.3. Discussion
While fgetss( ) is convenient if you need to strip tags from a file as you read it in, it may get confused if tags span lines or if they span the buffer that fgetss( ) reads from the file. At the price of increased memory usage, reading the entire file into a string provides better results:
$no_tags = strip_tags(join('',file('test.html')));Both strip_tags( ) and fgetss( ) can be told not to remove certain tags by specifying those tags as a last argument. The tag specification is case-insensitive, and for pairs of tags, you only have to specify the opening tag. For example, this removes all but <b></b> tags from $html:
$html = '<a outsideurl=">I <b>love</b> computer books.</a>'; print strip_tags($html,'<b>'); I <b>love</b> computer books.
