![]() print command & escape character for string outputs.echo command & escape character for string outputs.Introduction to PHP: How scripting languages work.← Introduction to PHP Sample codes in PHP →Ĭheck the string or number is Palindrome or not in PHP → Let us try with some simple PHP examples. Now script execution will stop after 2 seconds Set_time_limit ( 2 ) // Max execution time is set to 2 seconds ![]() This value of 30 seconds is set at php.ini file, we can change this upper limit of execution time by using ini_set() function.Įrror_reporting(E_ALL) // Display all types of error Server stops the execution of the script after 30 seconds. Inside the loop each time we are resetting the value of $i to 5, so it can never reach value of 10 to exit the loop.įatal error: Maximum execution time of 30 seconds exceeded in H:\php_files\plus2net\z\for.php on line 18 What happens when we keep a condition which the loop can never meets? While loops are used for conditional looping. Here we have printed from 1 to 10 numbers, by changing the values inside the for loop you can print numbers starting from any value to ending at any value.įor loop is used when we know exactly how many times the looping is required. This way all numbers will be printed in one new line. In the next line we have used the same echo command to print one html line break. The echo command will print the value of $i to the screen. You can easily extend this program to print any numbers from starting from any value and ending on any value. ![]() We can print numbers from 1 to 10 by using for loop. So I wrote the function getrange($min,$max) that exactly does this.For and foreach loop in PHP with break statement and creating patterns using nested for loops This could be used for example to get the excel column indexes.Į.g. ![]() The function "range" is very useful to get an array of characters as range('C','R') does.Īt work, I had to extend the function range($a,$b) to work in this special case: with two uppercase strings $a and $b, it should return all the possible strings between $a and $b.
