[PHP] regex help needed
Sorry,
Here is the code I am using to match the h* tags:
h([1-9]){1}.*/h([1-9]){1}
I have removed all the NL and CR chars from the string
I am matching to make things easier. Also, I have run
tidy on the code so the tags are all uniform.
The above string seems to match the tag well now, but
I still need to remove the br tags from the tag
contents (.*).
The strings I will be matching are html formatted
text. Sample h* tags with content are below:
h4Ex-Secretary Mickey Mouse br /Loses Mass.
Primary/h4
h4Ex-Secretary Mickey Mouse br /Loses Mass.
Primary br / Wins New Jersey/h4
h4Ex-Secretary Reich Loses Mass. Primary/h4
Again, any help is appreciated.

Simple:
while (preg_match(/(h\d)(.*)(br \/)(.*)(\/h\d)/is, $str)) {
$str = preg_replace(/(h\d)(.*)(br \/)(.*)(\/h\d)/is,
$1$2$4$5, $str);
}
$str = preg_replace(/(h\d)(.*)(\/h\d)/is, $2, $str);
Recommended:
$str = preg_replace(/(h\d)([^]*)()(.*)(\/h\d)/eis, remove_br('$4'), $str);
function remove_br($str){
return preg_replace(/(br)([^]*)()/i, , $str);
}

[PHP] Regex help needed
Hello, Well I am doing by first reg ex operations and I am having problems which I just cannot figure out. For example I tried echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font size=\2\\s*purchasing power parity, '%POWER%', 'tdtrsdsdsstr bgcolor=#f8f8f1tdfont size=2Purchasing power parity'); and this worked perfectly, but when I chnaged that to echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font size=\2\\s*purchasing\s+power\s+parity, '%POWER%', 'tdtrsdsdsstr bgcolor=#f8f8f1tdfont size=2Purchasing power parity'); It does not detect the string. Srange. According to what I know, \s+ will detect a single space also. I tried chnaging the last 2 \s+ to \s* but this did not work also. Any ideas on this one? As I proceed I would like the expression to detect the optional face attribute also, so I tried echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font size=\2\(\s+face=\Verdana, Arial, Helvetica, sans-serif\|)\s*purchasing power parity, '%POWER%', 'tdtrsdsdsstr bgcolor=#f8f8f1 face=Verdana, Arial, Helvetica, sans-seriftdfont size=2Purchasing power parity'); ... and this gave me an error like Warning: eregi_replace(): REG_EMPTY:çempty (sub)expression in D:\sid\dg\test.php on line 2 Any ideas? BTW any place where I can get started on regex? I got a perl book that explains regex, but I have got to learn perl first (I dont know any perl) Thanks in advance. - Sid

try ereg_replace("^[ ]+(.)[ ]+$", '_\\1_', $here)
I haven't tested it, but if it won't work, then do this:
$here = ereg_replace("^[ ]+", '_', $here)
$here = ereg_replace("[ ]$", '_', $here)
this should work...

Thank you for your suggest, but I don't want to just trim them, I need to
display them as underscores (_).

This should be a quick one, but I can't seem to wrap my brain around it.
All I need to do is replace leading or trailing spaces with underscores.
If
there is spaces in between words, leave them alone.
Suggestions?

This is very close. If the string, " Testing ", had multiple spaces, but
I wanted to convert each space to a "_", then what? I tried:
$fix = ereg_replace("(^ +)|( +$)", "_", $checkme);
and
$fix = ereg_replace("(^[ ]+)|([ ]+$)", "_", $checkme);
with no success.
Thanks for your help...

There may be a better way, but here is a lengthy one that works.
$checkme = " this is it ";
if(ereg("^( )+", $checkme, $match)) {
for($i = 0; $i strlen($match[0]); $i++) {
$start .= "_";
}
}
if(ereg("( )+$", $checkme, $match)) {
for($i = 0; $i strlen($match[0]); $i++) {
$end .= "_";
}
}
$fix = ereg_replace("^( )+", $start, $checkme);
$fix = ereg_replace("( )+$", $end, $fix);
echo "$fix";

$NewString = str_repeat ('_', strlen ($matches [1])).
$matches [2] .
str_repeat ('_', strlen ($matches [3]));
not tested, but should work fine.
That worked. Thank you very much.
