Some common methods to ease the life of anonymous PHP developers

String

• startsWith Tests if a string starts with the specified prefix.
• endsWith Tests if a string ends with the specified suffix
• camelize Uppercases the first character of each word in a string
• excerpt Creates an excerpt from a text based on a phrase
• truncate Truncates a given string after a given length (if necessary)
• highlight Highlights (i.e. adds html-tags arround the keyword) a given keyword in a string
• hashCode Get the integer based hash code of a given string

Array

• insertElement Adds an element into a array on the given position without replacing the old entry
• removeElementByValue Removes the given element from the array
• mergeArrayValues Creates an array of arrays from the two given arrays.
• getPrevKey Returns the previous key from an array
• getNextKey Returns the next key from an array
• applyCallbackByPath Applies a callback on a part of a multidimensional array defined by its path (i.e. keys)

Integer

• intcmp Compares two integers (similarly to strcmp) and returns whether the first argument is smaller, less or equal to the second argument.
• isInteger Checks if a given value can be interpreted as a "real" integer without commas or exponent parts (i.e. 1e10 is not treated as an integer).

Formatter

Byte

• prettyPrintSize Pretty prints a given memory/file size (e.g. 1024 -> 1kB)

Time

• prettyPrintMicroTimeInterval Pretty prints an interval specfied by two timestamps.
• getRelativeTimeDifference Get the relative difference between a given start time and end time.

HashCodeBuilder

Allows building a hash code by chaining different values defining an individual hash.

$hashBuilder = new HashBuilder();
$hashCode = $hashBuilder
    ->append($item->getId())
    ->append($item->isEnabled())
    ->append($item->getName())
    ->toHashCode();
