When you create a new project, Bundle identifier=organization identifier+product Name. But their recognition of Chinese is unified into a dash-.So when you create multiple projects, you need to be aware of them. Try to use less Chinese, if you want to use Chinese, then the guarantee is not pure Chinese or Chinese readme is not the same.

sub-array there are several pairs of reverse pairs (currently there are two elements, reverse to add 2,2+2=4), 7>6, after comparing the P1 point to the value into the auxiliary array, The auxiliary array now has a number 7 and then moves the P1 forward one point to 56. Again determine the value that P1 and P2 point to, p1 is less than P2, because P1 points to the largest value in the first subarray, so there is no number in the sub-array that can be reversed against the 6 that the current P2 po

Some examples:
>>mpdf-can generate PDF documents via HTML
>>phpexcel-Read and write Excel
>>phpmailer-easy to handle sending messages containing nearby
>>pchart-use PHP to generate reports
use open source libraries to accomplish complex tasks, such as building PDFs, ms-excel files, reports, etc.
