In Linux bash shell, semicolons in statements are generally used as code block identifiers.
1. A single-line statement generally uses semicolons to distinguish code blocks. For example:
Weblogic @ pmtest:/$ if ["$ PS1"]; then echo test is OK; fiTest is OK
In this script or command line, two semicolons are required for the correct statement. The first Semicolon is the semicolon before then, used to identify the end Of the condition block, and the second semicolon before fi, identifies the end

Static private int getpowersum (powersum PS){Return PS (10 );}
Call using delegated InferenceCodeAs follows:
Int P2 = getpowersum (squaresum );Int P3 = getpowersum (cubesum );
The code for creating a delegate object is as follows:
Powersum PS2 = new powersum (squaresum );Powersum PS3 = new powersum (cubesum );P2 = PS2 (10 );P3 = PS3 (10 ); 1.6. Net delegate Example 2: function callback

interface, it is likely that the power supply is insufficient. Therefore, almost all mobile hard disks are attached with a separate external power supply or a PS2 conversion interface powered by the keyboard. In this case, you only need to connect the external power supply in advance or connect the keyboard through The PS2 adapter, make sure that you have enough power for the mobile hard disk and try again
the hardware is too cheap.
There is also a variety of game hosts, such as PS2/PS2/gamecube/Wii, which are all variants of the standard ibm pc, designed for better computing and graphics capabilities. However, these buddies are not mixed up recently, because the iPhone has come out, and the computing and graphics capabilities of ordinary PCs are getting stronger and stronger. programmers who write games c

remove an incorrect match.In addition, when the matching points are used to calculate the base matrix, the feature points are first aligned and the feature points are converted to 2D points, which are implemented as follows: //Align All PointsVectorAlignedKps1, ALIGNEDKPS2; for(size_t i =0; I ) {alignedkps1.push_back (Leftpattern-Keypoints[matches[i].queryidx]); Alignedkps2.push_back (Rightpattern-Keypoints[matches[i].trainidx]); } //keypoints to pointsVectorPS1,

The backend is the PHP $_files variable to get the submitted file.
The normal form submission is this way.

My situation here is that the uploaded file is a string of base64 from outside, how to change this, in order to achieve the simulation form submission, the background does not need to change the code.
Ps:I try to put Base64 in the Formdata object, but the $_files variable in the background is still not recognized

Just as using modules, the authors of different modules do not have to worry about conflicting global variable names, using the module name with dots can enable the authors of multi-module packages, such as NumPy and PIL, not to worry about conflicting modules.
For example, the Python module can only be provided in systems that provide the amoeba underlying commands. One module deserves

Dynamic binding can inherit parameter values from base class. Note that I don't emphasize the concept of dynamic binding and static binding here, but th
