preg-match-all

问题 Why does the following evaluate to true ? if(preg_match_all('%<tr.*?>.*?<b>.*?</b>.*?</tr>%ims', $contents, $x)===FALSE) {...} $contents , is retrieved using file_get_contents() from this source. The regex was simplified to troublshoot the problem. The code I was actually using was: if(preg_match( '%Areas of Study: </P>.*?<TABLE BORDER="0">(.*?)<TBODY>.*?</TBODY>.*? </TABLE>%ims', $contents, $course_list) ) { if(preg_match_all('%<TR>.*?<TD.*?>.*?<B>(.*?)</B>.*?</TD>.*?<TD.*?>.*?</TD>.*?<TD.*?

问题 I am using PHP on shared server to access external site via API that is returning JSON containing 2 levels of data (Level 1: Performer & Level 2: Category array inside performer).

Example of JSON data: [ { "performerId": 99999, "name": " Any performer name", "category": { "categoryId": 99, "name": "Some category name", "eventType": "Category Event" },

问题 I want to find (if they exist) any hash tags and get the first co-occurrence of each tag plus the text after it but before the next tag if another exists. *Not all message strings carry a hash tag!

问题 I was wondering how can I create preg_match for catching: id=4 4 being any number and how can I search for the above example in a string? If this is could be correct /^id=[0-9]/ , the reason why I'm asking is because I'm not really good with preg_match . 回答1: for 4 being any number, we must set the range for it: /^id\=[0-9]+/ \ escape the equal-sign, plus after the number means 1 or even more. 回答2: You should go with the the following: /id=(\d+)/g Explanations: id= - Literal id= (\d+) -

问题 I am trying to make a small program that searches within a timer (with this format 00d 00h 00m 00s) and returns the days into one variable, the hours into another, etc. This is some of my code: $time1 = "Left: 11d 21h 50m 06s <\/div>" preg_match_all("/ .*d/i", $time1, $timematch); // Day $time1day = $timematch[1]; // Saves to variable preg_match_all("/ .*h/i", $time1, $timematch); // Hour $time1hour = $timematch[1]; // Saves to variable preg_match_all("/ .*m/i", $time1, $timematch); // Minute

问题 My task is to find all consecutive number in a string of only numbers. However I am not searching for a better regex to do this, but for a correct regex of matching substrings. This is how I build my regex: $regex = ""; for($i=0;$i<10;$i++) { $str = ""; for($a=0;$a<10;$a++) { if($a > $i) { $str .= $a; if(strlen($str)>1) { $regex .= "|".$str.""; } } } } $myregex = "/".ltrim($regex,"|")."/"; echo $myregex; Result: /12|123|1234|12345|123456|1234567|12345678|123456789|23|234|2345|23456|234567
