Solution 2: create an element with 'falsy' value ( 0, null, false, ''. Solution 1: jump over an ignorable element, using the method next() $a=array(0,1,2,3,4,5,6) //or $a=range(0,6) You can test it online on or on answer is the right way to go, but it won't be obvious for the untrained eye.ĭue to the iteration, the number 1 won't be echoed the 2nd time around. Unset($i) //delete the iterator, to free memory Ask Question Asked 9 years, 3 months ago. $a=array(1,2,3,4,5,6) //or $a=range(1,6) PHP How to count same words in foreach loop. It has the method rewind() which is the same as the reset() function. If you are a fan of OOP, you can use the ArrayIterator class. Don't rely on the array pointer during or after the foreach without resetting it.' That allows you to simply loop over the posts array and echo the value of the commentcount field or use the value to check for comments then embed an element etc. foreach has some side effects on the array pointer. Unless the array is referenced, foreach operates on a copy of the specified array and not the array itself.

However, thanks to a commenter, I found the text that used to be in the foreach: For example, in the code above, the first items value was indeed 10 and thats the value that first got enumerated in the foreach loop. Using 24 hour time, I tried to find last event of the day within the foreach loop and then when the endtime of last event of the day is less than now, show text, 'All scheduled events have concluded for today.

I thought I had seen before that you couldn't rely on the internal pointer in the foreach.but couldn't find it in the documentation this time.only 'unexpected results'. Remember that when using foreach, iteration happens over the given array in the exact same order in which items were originally added. Im trying to be able to count total events for a given day (today) for a specific venue. Not sure what 'unexpected behavior' is, as I've never tried this.but maybe safer to manually use each().also more clear in your code. This means that you do not need to call reset() before a foreach loop.Īs foreach relies on the internal array pointer, changing it within the loop may lead to unexpected behavior. Note: When foreach first starts executing, the internal array pointer is automatically reset to the first element of the array. How can I update code that uses the deprecated each() function? Original Answer for version < 7.2

list() = each() will not work for any PHP version >= 7.2. NOTE: Answer uses function deprecated as of PHP 7.2Īs pointed out in the comments. (php 5 > 5.5.0, php 7, php 8) It is possible to iterate over an array of arrays and unpack the nested array into loop variables by providing a list() as the value.
