there's no need to use regex, if you are not familiar. There are many string methods you can use in PHP, such as strpos $startpos = strpos($data,"<p>"); $endpos = strpos($data,"</p>"); echo substr($data,$startpos+strlen("<p>"),$endpos - $startpos);

no need regex if ( strpos($string,'\\') !==FALSE) { echo "found"; } check the online PHP manual for string functions.

echo substr($string,0,20) . "..";

specifying /images/userprofiles/ means your image file exists under the root directory's "image" directory. if you want to check whether your image file exists in the current directory, you might want to add a dot in front -> "./image/userprofiles" instead

he's initial question is why its starting at the third element. That's because the first few files are not what he wants AND the $i counter also increase. He need to somehow decrease(or remain?) the $i counter if a file is not what he wants.

google tells you what you can do

that's because of your if{} statement inside the for loop. You only check for jpg|jpeg|gif but what about the rest? If the file is not jpg or jpeg or gif, the counter $i will get incremented as well, that's why your array index doesn't start at 1( or 0) but at 2.

no need regex $string = "<p >Page: <div style='width:300px;'><div id=page-no><a href='/cat.php?cat_id=46&begin=0&num=1&numBegin=1'></a><font color='#ff3366'><b>1</b></font><a></a> </div><div style='float:left; clear:left;'><a href='/cat.php?cat_id=46&numBegin=1&num=2&begin=14'> Next Page >> </a></div></div>"; $startpos = strpos($string,"Page:"); $endpos = strpos($string,"Next Page"); echo substr($string,$startpos,$endpos-$startpos);

if you are not familiar with regex, then use PHP's string functions and break your data down into manageable chunks. for eg, if you want to check first 15 chars whether they are numbers if ( is_numeric( substr($message,0,15) ) ) { echo "yes, numbers\n"; } if you want to check date, you can use the checkdate() function $year = substr($message,15,4); $month = substr($message,19,2); $day = substr($message,21,2); if ( checkdate($month,$day,$year) ){ echo "Date ok\n"; } I leave it to you to do the rest. check the PHP manual for string function references. explode, implode can also be use to split,join your comma separated characters towards the end of the string.

echo preg_replace("/[^-a-zA-Z0-9]+/","",$s);

you should be using your own id , so you may want to specify your curl cookie options. eg cookiejar etc.. allow you may want to set followlocation to 1

how does your string looks like

use strip_tags eg $data = strip_tags($htmlpage,"<a>"); then you are left with all <a> tags. then you can split on "</a>" eg $splitted = split('</a>',$data); #not tested print_r($splitted); then you carry on your manipulation

take a look here

$str = '<a href="/sudden/businesses/display.cfm?recordid=2412">'; $domain = 'http://mydomain.com'; echo str_replace('<a href="','<a href="'.$domain,$str);

you can use a counter while () { $count++; if ( $count == 4 ){ echo "Next\n"; $count=0 } ..... .... }

my bad, misread the requirement. foreach ( split("\n",$data) as $k=>$v ){ $s = explode(". ",$v); echo end($s)."\n"; }

$line = 'my name is phpcodec and i like to code php and asp'; $letter="a"; echo substr_count($line,$letter); always check the PHP manual first for references on PHP functions.

if ( array_key_exists("4",range(0,7) )){ echo "yes"; }

don't have to be that complicated, here's one without the much regexp. split the file on closing braces. Check each value and display them if there is opening braces. $file="file"; $data = file_get_contents($file); $data = split("}",$data); foreach ($data as $k=>$v){ if( strpos($v,"{") !== FALSE){ echo "$v\n"; } } output: # ./test.php { Bracket line 1 { Bracket line 2 { Bracket line 3 tested only on your supplied data.

show your code, if possible

yes, i overlooked what he wants, my bad . Anyway, the difference is that even if i don't explain my code, OP should be able to understand what it's doing.

store each line as associative arrays, increasing the count as dups are found. At the end, check for count of more than 1. $contents=file("file"); foreach ($contents as $k=>$v){ $v=trim($v); $array[$v]++; } print_r($array);

$xmlfile = "file"; $fh=fopen($xmlfile,"r"); while( ( $line = fgets( $fh,4096) ) !==FALSE ){ if( strpos($line,'<day')!==FALSE ){ $day = split('"',$line); $date = $day[1]; continue; } if ( strpos($line,"<shift>")!==FALSE){ $sh = split("<endtime>",$line); $sh[1]=$date . $sh[1]; echo join("<endtime>",$sh); }elseif( strpos($line,"</day>") !==FALSE) { continue; }else{ echo $line; } } fclose($fh);

the way to work with strings is to think simple. break your work functions into simple steps. Here's a way without using complex regex. $file="file"; // since you said its recurring, we can split on <b> $data=split("<b>",file_get_contents($file)); foreach ($data as $k => $v){ if( !empty($v)) { // split on <br> $s = split("<br>",$v); print_r($s); //work on $s from here to get your items. } }
