This code was written to present one-time headers at the top of blocks of data where this makes sense (a working example is at the top of the foreach and another farther down) but not at the bottom of the page for data that is above it as I am trying to make it do now. Since $PageNo will always be different than $last_pageno the first time around because $last_pageno as yet has no value until it is set on the next line by $last_pageno = $PageNo. Then, in the loop, a condition looks to see if it is different than $PageNo and this is the part that is broken in the function. The purpose of global $last_pageno is to initiate the variable and set it without any value. PHP then iterates over this new copy of the array rather than the original one. In foreach loop, the first thing php does is that it creates a copy of the array which is to be iterated over. How about something like this Read off the first key and value using key() and current(), then arrayshift() to dequeue the front element from the array (EDIT: Don't use arrayshift(), it renumbers any numerical indices in the array, which you don't always want). I did not show the database connections as there are no issues with them. PHP foreach loop can be used with Indexed arrays, Associative arrays and Object public variables. If the condition is true the statement is repeated as long as the specified condition is true. dowhile the block of code executed once and then condition is evaluated. while loops through a block of code as long as the condition specified evaluates to true. To loop through a list of key-value pairs. PHP supports four different types of loops. It loops over the array, and each value for the. Make sure your rewind() implementation tries to grab the first result so that the subsequent call to valid() will know whether or not the result set is empty. In PHP, the foreach loop can be used to loop over an array of elements. The foreach loop is mainly used for looping through the values of an array. $PageNo is a value from a field in the database and the foreach loop is below with the function being called toward the end of it. Otherwise your code will break if the same iterator is used in two consecutive foreach loops when the first loop terminates with a break statement before all the results are iterated over. I have tried to use How to determine the first and last iteration in a foreach loop and PHP - Grab the first element using a foreach somehow it is not wroking out. I don't know in advance how many rows there will be on any given page and used 41 only as an example of one of the data sets. I want to add a different styling to my first item in the loop.
