Several ways to improve the efficiency of PHP programs_PHP Tutorial

1. Replace i=i+1 with i+=1. It conforms to the habits of c/c++ and is highly efficient.
2. Use PHP internal functions as much as possible. Before writing a function yourself, you should check the manual in detail to see if there are any related functions, otherwise it will be a thankless task.
3. If you can use single-quoted strings, try to use single-quoted strings. Single quoted strings are more efficient than double quoted strings.
4. Use foreach instead of while to traverse the array. When traversing the array, the efficiency of foreach is significantly higher than that of the while loop, and there is no need to call the reset function. The two traversal methods are as follows:
reset ($arr);
while (list($key, $value) = each ($arr)) {
echo "Key: $key; Value: $value< ;br>n";
}
foreach ($arr as $key => $value) {
echo "Key: $key; Value: $value
n";
}
The above points have been tested by the author. Please correct me if there are any deficiencies.
