Let's say we have an array of marks and want to modify values less than 40 by doubling them, while keeping other values unchanged ? Original marks: Array ( [0] => 45 [1] => 67 [2] => 89 [3] => 34 [4] ...
Read MorePHP fetch a specific value that begins with a given number from a string with letters and numbers?
In PHP, you can extract a specific value that begins with a given number from a string containing letters and numbers using substr() combined with strpos(). Syntax substr(string, start_position, length) strpos(string, search_value) Example Let's extract a value beginning with "989" from a mixed string − The actual value is: 1045632245555fghjklm67535454663443gfdjkbvc9890000006777743 The filtered value is: 9890000006777743 How It Works The solution works in two steps − strpos($value, "989") − Finds the position where "989" first occurs in the string substr($value, position, 16) − Extracts ...

Read MoreHow do I use the ternary operator ( ? : ) in PHP as a shorthand for "if / else"?
The ternary operator (? :) in PHP provides a compact way to write simple if-else statements in a single line. It evaluates a condition and returns one of two values based on whether the condition is true or false. Syntax The basic syntax of the ternary operator is − $variable = condition ? value_if_true : value_if_false; Basic Example Here's how to use the ternary operator to check if a value meets a condition ? Greater Than or Equal to 100 Comparison with If-Else The ...
Read MorePHP How to add backslash inside array of strings?
To add backslashes inside an array of strings, you can use json_encode() function twice. This technique is useful when you need to escape quotes within JSON strings for JavaScript or database storage. Let's say the following is our array − $value = [ "ADD", "REMOVE", "SELECT", "MODIFY" ]; We want the output with backslashes inside array of strings i.e − "["ADD", "REMOVE", "SELECT", "MODIFY"]" Using Double json_encode() The PHP code is as follows − This will produce the following output − ...
Read MoreIf elseif else or ternary operator to compare numbers PHP?
In PHP, you can compare numbers using if-elseif-else statements or the ternary operator (?:). Both have identical performance, but the ternary operator provides a more concise syntax for simple comparisons. Using if-elseif-else Statement The traditional approach uses conditional statements to compare numbers ? Value1 (10) is less than Value2 (20) Using Ternary Operator The ternary operator provides a compact way to write simple conditional statements ? 15 is greater Nested Ternary for Multiple Comparisons You can chain ternary operators for ...
Read MoreHow can I count true and false values in my PHP array?
In PHP, you can count true and false values in an array using array_filter() combined with count(). The array_filter() function removes falsy values by default, making it perfect for counting true values. Syntax $trueCount = count(array_filter($array)); $falseCount = count($array) - $trueCount; Example Let's count true and false values from a boolean array − Number of false values: 5 Number of true values: 4 How It Works The array_filter() function removes all falsy values (false, 0, null, empty string) from the array. When we count the ...
Read MoreReturn an array with numeric keys PHP?
In PHP, you can convert an associative array to an array with numeric keys using the array_values() function. This function returns all the values from an array with numeric indexing, starting from 0. Syntax array_values(array $array) Parameters $array − The input array from which to extract values. Return Value Returns an indexed array containing all the values from the input array with numeric keys starting from 0. Example Here's how to transform an associative array into a numerically indexed array ? The output of the ...
Read MorePHP array_push() to create an associative array?
In PHP, array_push() is designed for indexed arrays and automatically assigns numeric keys. To create associative arrays with custom key-value pairs, use square bracket notation [] or direct assignment instead. Why array_push() Doesn't Work for Associative Arrays The array_push() function appends values to the end of an array with numeric indexes, which destroys associative keys ? Array ( [name] => John [age] => 25 [0] => Developer ) Creating Associative Arrays with Square Brackets Use square bracket ...
