![]() ![]() ![]() In both cases, an eventual backtracking is unnecessary. I got a string: this,is,a','b,test I want to explode it on commas except for commas that are wrapped in double quotes, these should be left unharmed. The first two because the character class doesn't contain the next character, and the last because it is at the end of the pattern. Note that the quantifiers in +', in +\) but also in + are all automatically optimized to possessive quantifiers at compile time due to "auto-possessification". I am grabbing GET variables that will look like typeX, optionX, groupX, etc. + Any characters except commas one or more times explode() function takes the delimiter/separator string, and the original string as arguments, and returns an array of strings obtained after splitting the. This seems like it must be so simple, but regular expressions are extremely confusing to me. The trick is to match parenthesis before the, ~ Pattern delimiter These functions create an array by dividing. Preg_match_all("~'+'|\(+\)|+~", $string, $result) Three built-in functions of PHP that can be used to split string data are explode(), strsplit(), and pregsplit(). You can do the job using preg_match_all $string="a,b,c,(d,e,f),g,'h, i j.',k" Then I can explode it by commas and the replace the $separator with the original comma. This, will replace all the commas between the parenthesis. These functions perform a similar task to the explode( ). $String=ereg_replace($Pattern,"(\\1$separator\\2)",$String) They split the source string into an array, breaking the string where the matching pattern is found. This is what I have done so far, which is very slow for the strings having a long part between parenthesis: $separator="*" // whatever which is not used in the string I think using regular expressions will be a fast as well as clean solution. But if you're not using 5. The third parameter however should be set to true. On the last segment, func will be called with just one argument. When func is called, the first argument is the segment and the remaining arguments are the captures from sep, if any. This splits a string using the pattern sep. How can I explode that to get the following result? Array(=>"a",=>"b",=>"c",=>"(d,e,f)",=>"g",=>"'h,i j'",=>"k") The function strstr() in PHP 5.3 should do this job. Method: Split a string with a pattern, Take One. Possible values: Greater than 0 - Returns an array with a maximum of limit element (s) Less than 0 - Returns an array except for the last -limit elements () 0 - Returns an array with one element. If a value is a sentence, it should be between single quotations): $string="a,b,c,(d,e,f),g,'h, i j.',k" Specifies the number of array elements to return. I have a string as below (the letters in the example could be numbers or texts and could be either uppercase or lowercase or both. ![]()
