preg-match

If my string is : aud\ios , how do i check it out for the presence of \ in it? I tried using preg_match('\\' , $string) but it does not work. What's the correct way to achieve this? Amal Murali For something simple as this, you don't need a regular expression. A string function like strpos() should be enough: if (strpos('aud\ios', '\\') !== FALSE) { // String contains '\' } Note that you need to escape the backslash here. If you simply write \ , then PHP considers it as an escape sequence and tries to escape the character that follows. To avoid this, you need to escape the escape using another

I assume I need to use preg_match , but I am not really sure and like to know how to code it or if there are any other ways or function I can use. You can use: if(preg_match('#".*?\/(.*?)"#',$str,$matches)) { $filename = $matches[1]; } Alternatively you can extract the entire path between the double quotes using preg_match and then extract the filename from

Im working on some function to grab few data from url with simple html dom. But one of the data is an image and image have question mark and some more info behind it. So example of url would be something like this. http://somesite.com/uploaded/images/8.jpg?m=eSuQKgaaaa&mh=t0i7nVhjZleTJ5Ih So this content behind question mark is some sort of the code that makes images resized to small size. If i would just take this http://somesite.com/uploaded/images/8.jpg Images would be in bigger resolution and that's what i need. I know there is a function like preg_match but i never understood expressions

I'm looking for a pattern that accept only hebrew or english letters from 2 letters to 15, and can accept 1 space. I have tried following code but it does not matching my string: <?php $subject = "שלום לך"; $regexp="#^\p[{Hebrew}| ][a-zA-Z]{2,15}? \+$#u"; print_r(preg_match($regexp, $subject)); ?> There are multiple errors in your code. First, your regex $regexp="#^\p[{Hebrew}| ][a-zA-Z]{2,15}? \+$#u"; Here is what it means: # : regex delimiter ^ : begining of string \p : character p [{Hebrew}| ] : character class, one of the char : {, H, e, b, r, w, }, |, space [a-zA-Z]{2,15}? : from 2 to 15

I'm attempting to make something like shortcodes in WordPress, and I'm looking for a regex that will take something like [title:This is a title] and turn it to just This is a title . It would also be useful if someone could suggest a way to take something like [code:some code] and turn that into an array in the form of array( [0] => 'code' [1] => 'some code') or array( 'code' => 'some code' I've tried a few different regexes I've found here and there, but none of them seem to work. Thanks preg_replace('/\[.*?:(.*?)\]/', '$1', $str); CodePad . If you wanted to capture the text before the colon,

If I have a string "Hello I went to the store today" and I had an array of matches $perfectMatches = array("i went","store today"); It should match both of those. (the array can get quite large so i'd prefer to do it in 1 preg_match) Edit: Got this one working! thanks! preg_match_all("/\b(" . implode($perfectMatches,"|") . ")\b/i", $string, $match1) I also need a separate regular expression that is kind of hard to explain. Say I have an array $array = array("birthday party","ice cream");//this can be very long Is it possible to get a regular expression that will match a string if "birthday"

I have these strings. I want a regular expression to match them and return true when I pass them to preg_match function. do you want to eat katak at my hometown? do you want to eat teloq at my hometown? do you want to eat tempeyek at my hometown? do you want to eat karipap at my hometown?
