Generally we iterate over a set of data, we need to create a data, if the array is large, it will consume a lot of performance, and even cause low memory throw error Like what: Fatal error:allowed memory size of 134217728 bytes exhausted (tried to allocate + bytes) in D:\php\test\index.php on L Ine 5range (1, 100000000); PHP5.5 introduces the concept of iterative generators, the concept of iteration is already in

You mentioned "Language builder", English is "language construct", is the meaning of language composition, translation into a language builder is inevitably a bit confusing. PHP has several special keywords, such as echo, print, die, require, and so on, although they work like functions, they are actually more like if, while such as control statements, rather tha

returning a value. Example Simple example of #1 output value The above routines will output: 123 Note: Internally, the serialized integer key will be paired with an output value, just like a non-associative array. Caution If you use yield in a context expression (for example, in an assignment statement to the right of the equals sign), be sure to enclose it in parentheses. For example, the following code is correct: $data = (yield $value); However, the following code will have a parse error: $

, 250, 250, 100); Pdf_stroke ($pdf); Pdf_end_page ($pdf); Pdf_close ($pdf); If you want to output directly to the client, add the following code $buf = Pdf_get_buffer ($p); $len = strlen ($BUF); Header ("Content-type:application/pdf"); Header ("Content-length: $len"); Header ("Content-disposition:inline; Filename=pie_php.pdf "); Print $buf; Pdf_delete ($p); ?> Run the above program and enter a different number, and you will get a different pie chart.

consumption: 386912 memory consumption after generating array: 387520 memory consumption after release: 386944The memory difference used before and after is: 387520-386912 = 608Obviously 608 is far greater than 32, not to say that it is to reduce memory utilization. Then adjust the value of the loop to try it. Change 100000 to 10000000Use the CLI mode again to find out that the yield will be an error.PHP Fatal Error: 134217728134217736 in/data/wwwroot/default7But yield is still 608, because it
