preg-split

问题 preg_split has an optional PREG_SPLIT_DELIM_CAPTURE flag, which also returns all delimiters in the returned array. mb_split does not. Is there any way to split a multibyte string (not just UTF-8, but all kinds) and capture the delimiters? I'm trying to make a multibyte-safe linebreak splitter, keeping the linebreaks, but would prefer a more genericaly usable solution. Solution Thanks to user Casimir et Hippolyte, I built a solution and posted it on github (https://github.com/vanderlee/PHP

问题 I've searched for hours. How can I separate a string by a "\" I need to separate HORSE\COW into two words and lose the backslash. 回答1: $array = explode("\\",$string); This will give you an array, for "HORSE\COW" it will give $array[0] = "HORSE" and $array[1] = "COW" .

问题 How can i get rid of trailing spaces in preg_split result without using preg_replace to first remove all spaces from $test string? $test = 'One , Two, Thee '; $test = preg_replace('/\s+/', ' ', $test); $pieces = preg_split("/[,]/", $test); 回答1: If it must be preg_split() (you actually required that in the question) then this might help: $test = 'One , Two, Thee '; $pieces = preg_split("/\s*,\s*/", trim($test), -1, PREG_SPLIT_NO_EMPTY); trim() is used to remove space before the first and

问题 I have a string that looks like this: aaaaa: lorem ipsum bb: dolor sit amet ccc: no pro movet What would be the best way to split the string into an array and get the following result in PHP? array[0]='aaaaa: lorem ipsum'; array[1]='bb: dolor sit amet'; array[2]='ccc: no pro movet'; I can write a function that finds the position of each ":", finds the length of the word before it, and splits the string.

问题 I've some text that i wish to parse $str = "text1<br/>text2<br/>text3 I've tried using print_r( preg_split("<br/>", $str)); but it is not giving me the desired output 回答1: Try the following: $str = "text1<br/>text2<br/>text3"; print_r(preg_split("/<br\/>/", $str)); I'm assuming missing the closing quote " at the end of the $str = "text1<br/>text2<br/>text3" is just a typo.

问题 I managed to implement a function that converts camel case to words, by using the solution suggested by @ridgerunner in this question: Split camelCase word into words with php preg_match (Regular Expression) However, I want to also handle embedded abreviations like this: 'hasABREVIATIONEmbedded' translates to 'Has ABREVIATION Embedded' I came up with this solution: <?php function camelCaseToWords($camelCaseStr) { // Convert: "TestASAPTestMore" to "TestASAP TestMore" $abreviationsPattern = '/'
