Explode over every other word

由 大兔子大兔子 提交于 2020-01-10 05:16:04
问题 Lets say I have a string: $string = "This is my test case for an example." If I do explode based on ' ' I get an Array('This','is','my','test','case','for','an','example.'); What I want is an explode for every other space: Array('This is','my test','case for','an example.'). The string may have an odd # of words, so the last item in the array may not contain two words. Anyone know how to do this? 回答1: I would look through the results, and concatenate the strings after the fact. 回答2: $matches

Explode datalist into array

由 懵懂的女人 提交于 2020-01-06 01:47:46
