Escape translated strings

gistfile1.txt

/**
 * Escape translated strings with:
 */

__( ‘Hello world’, ‘text-domain’ ); _e( ‘Hello world’, ‘text-domain’ );.

/**
 * If there is no HTML use:
 */
esc_html__( ‘Hello world’, ‘text-domain’ ); esc_html_e( ‘Hello world’, ‘text-domain’ );

/**
 * When there's some HTML use:
 */
wp_kses( __( ‘Hello world’, ‘text-domain’ ), $allowed_html_array );

An alternative (often better) pattern for translatable strings which would contain HTML is this:

/**
 * When there's some HTML use:
 */
printf(
    /* translators: 1: link open tag, 2: link close tag */
    esc_html__( 'Hello world %1$slink text%2$s', 'text-domain' ),
    '<a href="' . esc_url( $url ) . '">',
   '</a>'
);

Is there a better way to do this type of output which includes screen reader text (that I assume should not have the user HTML)?

edit_post_link(
	sprintf(
		wp_kses(
			/* translators: %s: Name of current post. Only visible to screen readers */
			__( 'Edit <span class="screen-reader-text">%s</span>', 'text-domain' ),
			array( 'span' => array( 'class' => array() ) )
		),
		get_the_title()
	),
	' <span class="edit-link">',
	'</span>'
);

@joyously, I would suggest the following as an alternative way of writing that code:

$post_link_template = sprintf(
	/* translators: 1: Screen reader span open tag; 2: Name of current post, Only visible to screen readers; 3: Span close tag */
	esc_html__( 'Edit %1$s%2$s%3$s', 'text-domain' ),
	'<span class="screen-reader-text">',
	esc_html( get_the_title() ), // If you want to allow for some HTML in post titles, you could use `wp_kses_post()` as an alternative here.
	'</span'
);

edit_post_link(
	$post_link_template, // WPCS: XSS ok - text escaped properly just above.
	' <span class="edit-link">',
	'</span>'
);

@joyously, I am currently doing this:

<?php
	edit_post_link(
		sprintf(
			'%1$s <span class="screen-reader-text">%2$s</span>',
			esc_html__( 'Edit', 'text-domain' ),
			get_the_title()
		),
		'<span class="edit-link">',
		'</span>'
	);
?>

@joyously - Here's an option if you're not wanting any tags from the title to appear:

<?php

edit_post_link(
	sprintf(
		// Translators: %s is the post title shown to screen readers.
		esc_html__( 'Edit%s' ),
		' <span class="screen-reader-text">' . wp_strip_all_tags( get_the_title() ) . '</span>'
	)
);

Thanks, I think @justintadlock has the best version since the HTML is of no use to screen readers.
But I've been thinking lately that the screen reader user might be better off with "Edit current post", rather than "Edit Hello World!".

i am currently working with codeigniter can i use html_escape?
